               AIRPORT SYSTEMS INTERNATIONAL, INC. AND SUBSIDIARY
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
                                JANUARY 31, 1997


1.       Basis of presentation

The accompanying unaudited condensed consolidated financial statements of
Airport Systems International, Inc. (the Company) include the accounts of the
Company and its wholly owned subsidiary, ASII International, Inc., a foreign
sales corporation incorporated in Barbados.  All intercompany balances and
transactions have been eliminated.  The condensed consolidated financial
statements have been prepared in accordance with generally accepted accounting
principles for interim financial information and with the instructions to Form
10-QSB.  Accordingly, they do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements.  In the opinion of management, all adjustments (consisting of
normal recurring accruals) considered necessary for a fair presentation have
been included.  Operating results for the three months and nine months ended
January 31, 1997, are not necessarily indicative of the results that may be
expected for the year ended April 30, 1997.  For further information, refer to
the consolidated financial statements and footnotes included in the Airport
Systems International Inc. and Subsidiary annual report on Form 10-KSB for the
year ended April 30, 1996.

2.       Notes Payable to Banks

During September, 1996, the Company amended its line of credit to provide for
maximum borrowings of $4,000,000, at an interest rate of prime (8.25% at
January 31, 1997), secured by accounts receivable, inventory, and equipment.
The agreement matures in September, 1997. There were no borrowings outstanding
at January 31, 1997.

The discussions set forth in this Form 10-QSB may contain forward-looking
comments based on current expectations that involve a number of risks and
uncertainties.  Actual results could differ materially from those projected or
suggested in the forward-looking comments.  The difference could be caused by a
number of factors, including, but not limited to the factors and conditions
which are described under the headings  "Results of Operations," and "Backlog,"
the timely completion of financing for the Indonesia project through the
Export/Import Bank of the United States, and competitive and pricing pressures
related to all contracts.  Further information on the factors that could affect
the Company's financial results are included in the Company's other SEC
filings, including the Form 10-QSB for the quarters ended July 31, 1996 and
October 31, 1996, and the Form 10-KSB for the year ended April 30, 1996.  The
reader is cautioned that the Company does not have a policy of updating or
revising forward-looking statements and thus he or she should not assume that
silence by management of the Company over time means that actual events are
bearing out as estimated in such forward-looking statements.


                ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

Sales for the third quarter of fiscal 1997 were $3.6 million compared to $3.7
million for the third quarter of fiscal 1996.  Sales for the first nine months
of fiscal 1997 increased 32.5%, to $12.8 million from $9.7 million for the same
period in fiscal 1996.  The increase in sales for the nine months is due to an
increase in units shipped as a result of a higher beginning backlog and
increased bookings compared to the same period of fiscal 1996.

Gross margin remained unchanged in the third quarter of fiscal 1997 compared to
the third quarter of fiscal 1996.  Gross margin for the first nine months of
fiscal 1997 increased to $3.9 million (or 30.3% of sales) compared to $2.7
million (or 28.0% of sales) for the first nine months of fiscal 1996.  Gross
margin as a percent of sales increased during both periods compared to the
comparative periods in fiscal 1996 due to the delivery of higher gross margin
products and services as well as reduced manufacturing costs.  In addition, the
Company's mix of international sales increased from 65% of total sales in the
fiscal 1996 nine month period to 88% of total sales in the fiscal 1997 nine
month period.  As international sales have historically generated a higher
gross margin, this change in mix also contributed to the increase in the gross
margin. The Company expects gross margins to continue to fluctuate due to the
timing and mix of contract awards and delivery of product and services.

Selling, general, and administrative expenses decreased during the third
quarter to $854,000 (23.5% of sales) from $914,000 (24.9% of sales) in the
third quarter of fiscal 1996.  The decrease in dollar terms reflects reduced
marketing travel expense as compared to the same period of the prior year.  For
the first nine months of fiscal 1997, selling, general, and administrative
expenses increased to $2.9 million (22.8% of sales) from $2.6 million (26.8% of
sales) in the same period





                                     Page 7
<PAGE>   8

of fiscal 1996.  The increased dollar amount is principally due to increased
marketing and selling costs resulting from the growth in sales, backlog, and
international marketing opportunities.  The decrease as a percent of sales is
primarily due to economies of scale associated with higher sales as certain
costs are fixed in nature.

Research and development expenses increased during the third quarter to
$265,000 from $245,000 in the third quarter of fiscal 1996.  The increase
reflects increased expenses related to the GPS navaids product site
installation and flight tests as well as the initiation of research and
development programs designed to enhance the current product line.  In the
first nine months, research and development expenses decreased to $712,000 from
$806,000 for the first nine months of fiscal 1996.  The decrease is a result of
decreased labor associated with the current integration and testing stage of
the Company's GPS navaids product during the first six months, partially offset
by the increased activity in the third quarter.  In the comparative period of
fiscal 1996, the Company was primarily involved in the more labor intensive
initial design stage of the project which resulted in higher levels of research
and development expenses.

Interest expense decreased $7,000 for the third quarter and $26,000 for the
first nine months compared to the respective periods in the prior year due to a
decrease in the average debt obligations outstanding compared to the prior year
period. During the quarter ended January 31, 1997, the Company settled a
lawsuit with a former sales representative resulting in a non-recurring charge
of $83,000 relating to this litigation settlement.

The Company's estimated provision (benefit) for income taxes amounted to
(36.4%) and 36.9% for the third quarter and first nine months, respectively,
resulting from the generation of pretax losses for the third quarter of fiscal
1997, but pretax income for the first nine months of fiscal 1997.  In the
prior year comparative periods, the Company recorded an effective income tax
benefit of approximately 38% due to the Company's loss position.

The net loss for the third quarter was $98,000, compared with a fiscal 1996
third quarter net loss of $74,000.  For the first nine months, net income was
$99,000, compared with a net loss of $441,000 for the first nine months of
fiscal 1996. The increase in net income is primarily due to increased sales and
gross margin, as previously mentioned.


BACKLOG

The Company's backlog was $7.4 million at January 31, 1997, compared to $6.5
million at January 31, 1996, and $6.5 million at April 30, 1996.  Approximately
59% of the backlog at January 31, 1997, was represented by three contracts.
The contracts call for providing navaid equipment to Taiwan (15% of backlog),
Canada (14% of backlog) and the Federal Aviation Administration (30% of
backlog). The Company expects to ship approximately $2.4 million of the total
backlog through the end of the fiscal year.





                                     Page 8
<PAGE>   9

The increase in backlog, as compared to April 30, 1996, is the result of
approximately $5.3 million in contract awards during the third quarter. These
contracts represented a mix of sales to new and existing customers in the
United States, Canada, the Middle East and the Pacific Rim. During the quarter,
the Company announced the signing of a $17.7 million contract with the Republic
of Indonesia.  Upon financing approval from the Export/Import Bank of the
United States, the contract will be recorded in backlog.  While the Company is
confident it can obtain approval of the financing over the next several months,
a delay could effect results during the Company's fourth quarter of fiscal
1997.  Other bids remained active at quarter end, but the Company is unable to
determine when or if the related contracts will be awarded.  The Company
expects backlog and bidding activities as well as contract awards to continue
to fluctuate due to the size and timing of contract programs.

LIQUIDITY AND CAPITAL RESOURCES

Net cash of $26,000 was used by operations for the first nine months of fiscal
1997 compared to $1,343,000 used in the first nine months of fiscal 1996.  The
decrease was the result of higher net income compared to the same period in
fiscal 1996 and cash provided by increased customer deposits reflected as
accrued expenses offset by increases in accounts receivable and inventory. The
increase in accounts receivable and inventory represents the granting of longer
credit terms on certain contracts and a build-up of inventories for upcoming
contracts, respectively.

Cash used in investing activities was $99,000 for the first nine months of
fiscal 1997 compared to cash provided of $1,315,000 in the first nine months of
fiscal 1996. The decrease in cash provided is primarily the result of the
liquidation of short-term investments in the prior year period of $1,939,000.

Cash used in financing activities was $10,000 in the first nine months of
fiscal 1997 compared to cash used of $9,000 in the first nine months of fiscal
1996 as a result of the normal paydown of the Company's debt obligations.

The Company expects that it will meet its ongoing requirements for working
capital and capital expenditures from a combination of cash expected to be
generated from operations, existing cash and cash equivalents, and available
borrowings under its existing revolving credit facility.

                      CHAPTER 4.  ON-AIRPORT VOR (NO FAF)

400.     GENERAL.

         This chapter is divided into two sections:  one for low altitude
procedures and one for high altitude teardrop penetration procedures.  These
criteria apply to procedures based on a VOR facility located on an airport in
which no final approach fix (FAF) is established.  These procedures must
incorporate a procedure or a penetration turn.  An ON-AIRPORT facility is one
which is located:

         a.      For Straight-In Approach.  Within one mile of the nearest
                 portion of the landing runway.

         b.      For Circling Approach.  Within one mile of the nearest portion
                 of the usable landing surface of the airport.

401.-409.        RESERVED.

                       SECTION 1. LOW ALTITUDE PROCEDURES

410.     FEEDER ROUTES.

         Criteria for feeder routes are contained in Para 220.

411.     INITIAL APPROACH SEGMENT.

         The initial approach fix is received by overheading the navigation
facility. The initial approach is a procedure turn. The criteria for the
procedure turn areas are contained in Paragraph 234.

412.     INTERMEDIATE APPROACH SEGMENT.

         This type of procedure has no intermediate segment. Upon completion of
the procedure turn, the aircraft is on final approach.

413.     FINAL APPROACH SEGMENT.

         The final approach begins where the procedure turn intersects the final
approach course inbound.

         a.      Alignment.  The alignment of the final approach course with
                 the runway centerline determines whether a straight-in or
                 circling approach may be established.

                 (1)      Straight-In.  The angle of convergence of the final
                          approach course and the extended runway centerline
                          shall not exceed 30 degrees.  The final approach
                          course should be aligned to intersect the extended
                          runway centerline 3000 feet outward from the runway
                          threshold.  When an
<PAGE>   81

                          operational advantage can be achieved this point of
                          intersection may be established at any point between
                          the runway threshold and a point 5200 feet outward
                          from the runway threshold.  Also, where an
                          operational advantage can be achieved, a final
                          approach course which does not intersect the runway
                          centerline, or intersects it at a distance greater
                          than 5200 feet from the threshold, may be established
                          provided such a course lies within 500 feet laterally
                          of the extended runway centerline at a point 3000
                          feet outward from the runway threshold.  See Figure
                          38.

                 (2)      Circling Approach.  When the final approach course
                          alignment does not meet the criteria for straight-in
                          landing, only a circling approach shall be
                          authorized, and the course alignment should be made
                          to the center of the landing area.  When an
                          operational advantage can be achieved, the final
                          approach course may be aligned to pass through any
                          portion of the usable landing surface.  See Figure 39.

         b.      Area.  Figure 40 illustrates the final approach primary and
                 secondary areas.  The primary area is longitudinally centered
                 on the final approach course, and is 10 miles long.  The
                 primary area is 2 miles wide at the facility and expands
                 uniformly to 6 miles at 10 mile from the facility.  A
                 secondary area is on each side of the primary area.  It is
                 zero miles wide at the facility and expands uniformly to 1.34
                 miles on each side of the primary area at 10 miles from the
                 facility.  When the 5 mile procedure turn is used, only the
                 inner 5 miles of the final approach area need be considered.

         c.      Obstacle Clearance.

                 (1)      Straight-In.  The minimum obstacle clearance in the
                          primary area is 300 feet.  In the secondary area, 300
                          feet of obstacle clearance shall be provided at the
                          inner edge, tapering uniformly to zero feet at the
                          outer edge.  The minimum required obstacle clearance
                          at any given point in the secondary area is found in
                          Annex C.  Figure 126.

         [Diagram - Figure 38.  Alignment Options for Final Approach Course.

         413.a.(1).]

                 (2)      Circling Approach.  In addition to the minimum
                          requirements specified in Para. 413.c.(1) obstacle
                          clearance in the circling area shall be as prescribed
                          in Chapter 2, Section 6.
<PAGE>   82

         d.      Procedure Turn Altitude (Descent Gradient).  The procedure
                 turn completion altitude shall be within 1500 feet of the MDA
                 (1000 feet with a 5 mile procedure turn), provided the
                 distance from the facility to the point where the final
                 approach course intersects the runway centerline (or the first
                 usable portion of the landing area for "circling only"
                 procedures) does not exceed 2 miles.  When this distance
                 exceeds 2 miles, the maximum difference between the procedure
                 turn completion altitude and the MDA shall be reduced at the
                 rate of 25 feet for each one tenth of a mile in excess of 2
                 miles.

NOTE:  For those procedures in which the final approach does NOT intersect the
extended runway centerline within 5200 feet of the runway threshold (see Para
413.a.(1)) the assumed point of intersection for computing the distance from
the facility shall be 3000 feet from the runway threshold.  See Figure 38.

         e.      Use of Step-down Fix.  Use of the step-down fix (para 288.c)
                 is permitted provided the distance from the facility to the
                 step-down fix does not exceed 4 miles.  Where the step-down
                 fix is used, the obstacle clearance (para 413.c.(1)) may be
                 reduced to 250 feet from the step-down fix to the MAP.  See
                 Figure 42 below.  See also Para 251.

421.     INITIAL APPROACH SEGMENT.

         The initial approach fix is received by overheading the navigation
facility.  The initial approach is a teardrop penetration turn.  The criteria
for the penetration turn are contained in Para 235.

422.     INTERMEDIATE APPROACH SEGMENT.

         This procedure has no intermediate segment. Upon completion of the
penetration turn, the aircraft is on final approach.

423.     FINAL APPROACH SEGMENT.

         An aircraft is considered to be on final approach upon completion of
the penetration turn. However, the final approach segment begins on the final
approach course 10 miles from the facility. That portion of the penetration
procedure prior to the 10-mile point is treated as the initial approach segment.
See Figure 43.

         a.      Alignment.  Same as low altitude (Para 413.a.).

         b.      Area.  Figure 43 illustrates the final approach primary and
                 secondary areas.  The primary area is longitudinally centered
                 on the final approach course, and is 10 miles long.  The
                 primary area is 2 miles wide at the facility, and expands
                 uniformly to 8 miles at a point 10 miles from the facility.  A
                 secondary area is on each side of the Primary area.  It is
                 zero miles wide at the facility, and expands uniformly to 2
                 miles each side of the primary area at a point 10 miles from
                 the facility.

         [Diagram - Figure 43. Penetration Turn On-Airport VOR. No. FAF. Para
         423.]

         c.      Obstacle Clearance.

                 (1)      Straight-In.  The minimum obstacle clearance in the
                          primary area is 500 feet.  In the secondary area, 500
                          feet of obstacle clearance shall be provided at the
                          inner edge, tapering uniformly to zero feet at the
                          outer edge.  The minimum required obstacle clearance
                          at any given point in the secondary area is shown in
                          Annex C, Figure 123.

                 (2)      Circling Approach.  In addition to the minimum
                          requirements specified in Para 423.c.(1), obstacle
                          clearance in the circling area shall be as prescribed
                          in Chapter 2, Section 6.

         d.      Penetration Turn Altitude (Descent Gradient).  The penetration
                 turn completion altitude shall be at least 1000 feet, but not
                 more than 4000 feet above the MDA on final approach.

         3.      Use of Step-down Fix.  The use of the step-down fix is
                 permitted provided the distance from the facility to the
                 step-down fix does not exceed 10 miles.  See Para 288.c.

         f.      Minimum Descent Altitude.  In addition to the normal obstacle
                 clearance requirement of the final approach segment (see Para
                 423.c.), the MDA specified shall provide at least 500 feet of
                 clearance over obstacles in the portion of the
<PAGE>   84

                 initial approach segment between the final approach segment
                 and the point where the assumed penetration turn tract
                 intercepts the inbound course.  See Figure 43.

424.     MISSED APPROACH SEGMENT.

         Criteria for the missed approach segment are contained in Chapter 2,
Section 7.  The missed approach point is the facility.  See Figure 43.  The
missed approach surface shall commence over the facility at the required
height.  See Para 274.

                   CHAPTER 5. TACAN, VOR/DME AND VOR WITH FAF

500.     GENERAL.

         This chapter applies to approach procedures based on the elements of
the VORTAC facility; i.e., VOR, VOR/DME, and TACAN, in which a final approach
fix (FAF) is established. The chapter is divided into two sections: Section 1
for VOR procedures which do not use DME as the primary method for establishing
fixes, and Section 2 for VOR/DME and TACAN procedures which use collocated,
frequency paired DME as the sole method of establishing fixes. When both the VOR
and TACAN azimuth elements of a VORTAC station will support it, a single
procedure, identified as a VOR/DME or TACAN shall be published. Such a procedure
may be flown using either a VOR/DME or TACAN airborne receiver and shall satisfy
TACAN terminal area fix requirements. See Para 286.d.

         Criteria for feeder routes are contained in Para 220.

511.     INITIAL APPROACH SEGMENT.

         Criteria for the initial approach segment are contained in Chapter 2,
Section 3.  See Figures 44 and 45.

512.     INTERMEDIATE APPROACH SEGMENT.

         Criteria for the intermediate approach segment are contained in
Chapter 2, Section 4.  See Figures 44 and 45.

513.     FINAL APPROACH SEGMENT.

         The final approach may be made either "FROM" or "TOWARD" the facility.
The final approach segment begins at the final approach fix and ends at the
runway or missed approach point, whichever is encountered last.

         a.      Alignment.  The alignment of the final approach course with
                 the runway centerline determines whether a straight-in or
                 circling-only approach may be established.  The alignment
                 criteria differs depending on whether the facility is OFF or
                 ON the airport.  See definitions in Para 400.

                 (1)      Off-Airport Facility.

                          (a)     Straight-In.  The angle of convergence of the
                                  final approach course and the extended runway
                                  centerline shall not exceed 30 degrees.  The
                                  final approach course should be aligned to
                                  intersect the runway centerline at the runway
                                  threshold.  However, when an operational
                                  advantage can be achieved, the point of
                                  intersection may be established as much as
                                  3000 feet outward from the runway threshold.
                                  See Figure 46.

                          (b)     Circling Approach.  When the final approach
                                  course alignment does not meet the criteria
                                  for a straight-in landing, only a circling
                                  approach shall be authorized, and the course
                                  alignment should be made to the center of the
                                  landing area.  When an operational advantage
                                  can be achieved, the final approach course
                                  may be aligned to any portion of the usable
                                  landing surface.  See Figure 47.

                 (2)      On-Airport Facility.

                          (a)     Straight-In.  The angle of convergence of the
                                  final approach course and the extended runway
                                  centerline shall not exceed 30 degrees.  The
                                  final approach course should be aligned to
                                  intersect the extended runway centerline 3000
                                  feet outward from the runway threshold.  When
                                  an operational advantage can be achieved,
                                  this point of intersection may be established
                                  at any point between the threshold and a
                                  point 5200 feet outward from the threshold.
                                  Also, where an operational advantage can be
                                  achieved a final approach course which does
                                  not intersect the runway centerline, or which
                                  intersects it at a distance greater than 5200
                                  feet from the threshold, may be established,
                                  provided that such a course lies within 500
                                  feet laterally of the extended runway
                                  centerline at a point 3000 feet outward from
                                  the runway threshold.  See Figure 48.

                          (b)     Circling Approach.  When the final approach
                                  course alignment does not meet the criteria
                                  for a straight-in landing, only a circling
                                  approach shall be authorized, and the course
                                  alignment should be made to the center of the
                                  landing area.  When an operational advantage
                                  can be achieved, the final approach course
                                  may be aligned to any portion of the usable
                                  landing surface.  See Figure 49.

                 b.       Area.  The area considered for obstacle clearance in
                          the final approach segment starts at the final
                          approach fix and ends at the runway or missed
                          approach point, whichever is encountered last.  It is
                          a portion of a 30-mile long trapezoid (see Figure 50)
                          which is made up of primary and secondary areas.  The
                          primary area is centered longitudinally on the final
                          approach course.  It is 2 miles wide at the facility,
                          and expands uniformly to 5
<PAGE>   87

                          miles wide at 30 miles from the facility.  A
                          secondary area is on each side of the primary area.
                          It is zero miles wide at the facility and expands
                          uniformly to 1 miles on each side of the primary area
                          at 30 miles from the facility.  Final approaches may
                          be made to airports which are a maximum of 30 miles
                          from the facility.  See Figure 51.  The OPTIMUM
                          length of the final approach segment is 5 miles.  The
                          MAXIMUM length is 10 miles.  The MINIMUM length of
                          the final approach segment shall provide adequate
                          distance for an aircraft to make the required
                          descent, and to regain course alignment when a turn
                          is required over the facility.  Table 14 shall be
                          used to determine the minimum length needed to regain
                          the course.

         c.      Obstacle Clearance.

                 (1)      Straight-In Landing.  The minimum obstacle clearance
                          in the primary area is 250 feet.  In the secondary
                          area 250 feet of obstacle clearance shall be provided
                          at the inner edge, tapering uniformly to zero feet at
                          the outer edge.  The minimum obstacle clearance at
                          any given point in the secondary area is shown in
                          Annex C, Figure 125
<PAGE>   88

                 (2)      Circling Approach.  In addition to the minimum
                          requires specified in Para 513.c(1) above, obstacle
                          clearance in the circling area shall be as prescribed
                          in Chapter 2, Section 6.

         d.      Descent Gradient.  The OPTIMUM descent gradient in the final
                 approach segment should not exceed 300 feet per mile.  Where a
                 higher descent gradient is necessary, the MAXIMUM permissible
                 gradient is 400 feet per mile.  (See also Para 288.a).

                 (1)      Straight-In Approach.  The descent gradient shall be
                          computed using the distance from the FAF to the
                          runway threshold and the difference in altitude
                          between the altitude over the FAF and the touchdown
                          zone elevation.

                          Note: This table may be interpolated.  If the
                          minimum lengths specified in the table are not
                          available, straight-in minimums are not authorized.
                          See Figure 51 for typical final approach areas.

                 (2)      Circling Approach.  The descent gradient shall be
                          computed using the distance from the FAF to the first
                          usable portion of the landing surface and the
                          difference in altitude between the altitude over the
                          FAF and the circling MDA.

         e.      Use of Fixes.  Criteria for the use of radio fixes are
                 contained in Chapter 2, Section 8.  Where a procedure is based
                 on a procedure turn and an on-airport facility is the
                 procedure turn fix, the distance from the facility to the FAF
                 shall not exceed 4 miles.

         f.      Minimum Descent Altitudes.  Criteria for determining the MDA
                 are contained in Chapter 3, Section 2.

514.     MISSED APPROACH SEGMENT.

         Criteria for the missed approach segment are contained in Chapter 2,
Section 7.  VOR procedures, the missed approach point and surface shall be
established as follows:

         a.      Off-Airport Facilities.

                 (1)      Straight-In.  The missed approach point is a point on
                          the final approach course which is NOT farther from
                          the final approach fix than the runway threshold.
                          See Figure 52.  The missed approach surface shall
                          commence over the missed approach point at the
                          required height.  (See Para 274).
<PAGE>   89

                 (2)      Circling Approach.  The missed approach point is a
                          point on the final approach course which is NOT
                          farther from the final approach fix than the first
                          usable portion of the landing area.  The missed
                          approach surface shall commence over the missed
                          approach point at the required height.  (See Para
                          274).

         b.      On-Airport Facilities.  The missed approach point is a point
                 on the final approach course which is NOT farther from the
                 final approach fix than the facility.  The missed approach
                 surface shall commence over the missed approach point at the
                 required height.  (See Paragraph 274).

                          SECTION 2. TACAN AND VOR/DME

520.     FEEDER ROUTES.

         Criteria for feeder routes are contained at Para 220.

521.     INITIAL APPROACH SEGMENT.

         Due to the fixing capability of TACAN and VOR/DME a procedure turn
initial approach may not be required. Criteria for initial approach segments are
contained in Chapter 2, Section 3.

522.     INTERMEDIATE APPROACH SEGMENT.

         Criteria for the intermediate segment are contained in Chapter 2,
Section 4.

523.     FINAL APPROACH SEGMENT.

         TACAN and VOR/DME final approaches may be based either on arcs or
radials. The final approach begins at a final approach fix and ends at the
missed approach point. The missed approach point is always marked with a fix.

         a.      Radial Final Approach.  Criteria for the radial final approach
                 are specified in Para 513.

         b.      Arc Final Approach.  The final approach arc shall be a
                 continuation of the intermediate arc.  It shall be specified
                 in nautical miles and tenths thereof.  Arcs closer than 7
                 miles (15 miles for high altitude procedures) and farther than
                 30 miles from the facility shall NOT be used for final
                 approach.  No turns are permitted over the final approach fix.

                 (1)      Alignment.  For Straight-In approaches, the final
                          approach arc shall pass through the runway threshold
                          when the angle of convergence of the runway
                          centerline and the tangent of the arc does not exceed
                          15 degrees.  When the angle exceeds 15 degrees the
                          final approach arc shall be aligned
<PAGE>   90

                          to pass through the center of the airport and only
                          circling minimums shall be authorized.  See Figure
                          53.

         Threshold. TACAN or VOR/DME. Para 523.b.(1).]

                 (2)      Area.  The area considered for obstacle clearance in
                          the arc final approach segments starts at the final
                          approach fix and ends at the runway or missed
                          approach point, whichever is encountered last.  It
                          should NOT be more than 5 miles long.  It shall be
                          divided into primary and secondary areas.  The
                          primary area is 8 miles wide, and extends 4 miles on
                          either side of the arc.  A secondary area is on each
                          side of the primary area.  The secondary areas are 2
                          miles wide on each side of the primary area.  See
                          Figure 54.

         [Diagram - Figure 54. ARC Final Approach Area. TACAN or VOR/DME. Para
         523.b.(2).]

                 (3)      Obstacle Clearance.  The minimum obstacle clearance
                          in the primary area is 500 feet.  In the secondary
                          area, 500 feet of obstacle clearance shall be
                          provided at the inner edge, tapering uniformly to
                          zero feet at the outer edge.  The minimum required
                          obstacle clearance at any point in the secondary area
                          is shown in Appendix 2, Figure 123.

                 (4)      Descent Gradient.  Criteria for descents are
                          specified in Para 513.d.

                 (5)      Use of Fixes.  Fixes along an arc are restricted to
                          those formed by radials from the VORTAC facility
                          which provides the DME signal.  Criteria for such
                          fixes are contained in Chapter 2, Section 8.

                 (6)      Minimum Descent Altitude.  Straight-In MDAs shall be
                          specified lower than circling for arc procedures.
                          Criteria for determining the circling MDA are
                          contained in Chapter 3, Section 2.

524.     MISSED APPROACH SEGMENT.

         Criteria for the missed approach segment are contained in Chapter 2,
Section 7.  The missed approach point shall be a radial/DME fix.  The missed
approach surface shall commence over the fix and at the required height.  (Also
See Para 514.)

NOTE:  The arc missed approach course may be a continuation of the final
approach arc.
