Avoid slow approaches.W ing drop and
increased sink rate may occur at 16.5 to
17.5 units AOA.
Auxiliary Flap Failure. A no-auxiliaryflaps
landing is basically the same as a normal landing
except that the approach speed is 6 knots faster than with
auxiliary flaps extcndcd, and the longitudinal stick position
during the approach is further aft. CV arrestments
are permitted; consult applicable recovery bulletin for
WOD requirements.

1. Wing sweep - Ensure at 20”.
2. AUX FLAP/FLAP CONTR cb - Pull (8G3).
3. Approach - 15 Units AOA.
Note
With AUX FLAP/FLAP CONTR cb pulled,
wings will not sweep aft.
15.7 WING-SWEEP EMERGENCIES
15.7.1 Aft Wing-Sweep Landings. CV arrestmerits
are permitted with up to 40” of wing sweep, and
emergency barricade engagements are permitted with
up to 35” of wing sweep. Shipboard aft wing-sweep
landings should be conducted at 15 units AOA. Field aft
wing-sweep landings may be conducted at AOAs up to
17 units when wings are stuck aft of 50” to minimize
approacha irspeedf or normal landings or remain within
published field arresting gear limitations for short-field
arrestedla ndings.M ain flaps and slatss hould beu tilized
to reduce approach speed with aft wing sweeps up to
50’. Maneuver flaps may be utilized if main flaps and
slats fail to extend.
If wings are determined to be stuck aft of 20” position:
1. Emergency WING SWEEP handle - Match
Captain Bars With Actual Wing Sweep Position
Tape.
Closely monitor wing-sweep movement
when attempting to match handle with wingsweep
position. Ifabnormal movement is noticed,
immediately return handle to previous
position.
2. Gross weight - Reduce as Required.
If wings < 50”:
3. Main flaps - FULL DN.
Note
Main flap/slat extension with the wings aft
of 20” will result in a large nosedown pitch
transient.
If main flaps are inoperative:
NAVAIR Ol-Fl4AAD-1
4. Maneuvering flaps - Extend.
pi&-(
If maneuvering flaps are used, ensure that
maneuver flap thumbwheel is not actuated
during the approach.
5. DLC and APC - Do Not Engage.
6. Slow-fly aircraft at a safe altitude to determine
approach airspeed (up to 17 units AOA for field
landings with wings aft of 50”) and to evaluate
handling/stall characteristics and waveoff performance.
Note
s Refer to emergency field arrestment guide
for maximum engagement speed if field
arrestmcnt is desired.
l Refert o Figure 1l -l for approacha irspeeds.
7. Fly straight-in approach at 15 units AOA (up to 17
units for field landings with wings aA of 50’).
Nozzle clearance is reduced at elevated approach
AOA. Ensure that a maximum of 17
units is maintained at touchdown.
Note
Maximum airspeed for wheelbrake application
is 165 knots at gross weight of 46,000
pounds and 145 knots at 51,000 pounds.
15.7.2 Asymmetric Wing Sweep. Refer to Chapter
11 for asymmetric wing-sweep design limitations
and flight characteristics.
With asymmetric wing-sweep emergency condition,
divert field landing is prcfcrable to CV landing attempt.
Aircrew must fully consider approach speed and aircrag
controllability characteristicsp rior to attempting CV arrestmcnt.
See Figure 15-2 for recommended approach
airspeed for 14 or 15 units AOA with asymmetric wing
configurations.
