LEF FAILURE
• LEF failures may be caused by an actuator failure (mechanical or two channel
failure) or by a switching valve failing to switch to the backup circuit following
a HYD circuit failure.
Speedbrake function and autopilot inoperative.
LEF actuators continue to operate following single channel failures. If a LEF
actuator is shutdown, the failed surface is mechanically locked in its current
position. The opposite LEF is held frozen by the FCCs except for differential
control in flaps AUTO. In most cases, the LEFs should be fairly symmetric;
however, multiple FCS reset attempts may aggravate the asymmetry.
Additionally, in flaps AUTO, aileron droop is set to zero, and TEFs are also held
fixed in their current position. However, in flaps HALF/FULL, TEFs and aileron
droop follow the normal schedules based on FLAP switch position. With a LEF
locked near 21° LED (±5°), flaps HALF/FULL handling qualities are essentially
normal. If locked above this position, stall margin is reduced. For LEFs locked

view over the nose is not degraded.
Slower engine response to throttle changes may result in excessive
sink rates under high WOD conditions. The recovery WOD should
be kept as close as possible to the Aircraft Recovery Bulletin
recommendations.
The aircraft response to power corrections is sluggish and small in magnitude.
Larger, longer, and more anticipatory power corrections are required to effect a
glideslope change. There is a tendency to over control the power due to the low
approach power setting and the longer time to effect a change. Power corrections
translate to an airspeed change first before a rate of descent change is noticed.
Aggressive, well-timed, and anticipatory throttle inputs are required for glideslope
control. The technique of applying power and waiting for a glideslope change will
lead to larger glideslope deviations. Waveoff performance is degraded. The
waveoff technique is the same as normal flap configurations. Time to achieve
positive rate of climb is slower than for normal TEF configurations. At the ship,
the waveoff window for a TEF failure condition should be moved farther out. The
LSOs should be aware of degraded waveoff and glideslope performance. Upon
bolter/waveoff, climb-out attitude will appear flatter than normal. The LSOs and
PRIFLY personnel should monitor rate of climb as the primary indication of
bolter/waveoff performance. It is recommended aircrew perform a familiarization
check of aircraft response to control and throttle inputs, including a waveoff
maneuver, prior to attempting a shipboard landing.

13.4 GROUND FIRE
Several fire conditions exist that may be detected and signalled by ground crew without correspond-
ing cockpit FIRE indications. These may include, for example, APU exhaust torching, ignition of fuel
or other flammable liquids exposed to hot surfaces, or brake assembly flash fires. Aircraft location and
the nature of the fire condition will determine the course of action. If a fire occurs during hot refueling,
the pilot must decide whether to taxi clear or shutdown immediately.
Brake flash fires can occur if excess grease or residual/leaking brake fluid have built up in the wheel
brake assembly or on the carbon discs. These materials may ignite at normal post landing brake
temperatures. Visible flames may extend from the wheel assembly while flammable material is being
consumed, and smoke may be visible for a short time after the fire goes out.
In most cases, if ground crew signal a fire condition, the aircraft should be stopped and shutdown
immediately. If the fire is related to the wheel brake system, consider chocking the nosewheel and
leaving the parking brake released to reduce the amount of heat transferred from the brakes to the
wheel assembly or to isolate a brake fluid leak which may feed a wheel brake fire.
13.5 EMERGENCY EGRESS

• The CANOPY switch should be used to raise the canopy unless there
are overriding circumstances. If weight is not on the left main gear
(e.g., gear up landing), the CANOPY switch must be held to raise the
canopy.
• If electrical power is not available, the canopy must be jettisoned or
raised with the handcrank.

CHAPTER 14
Takeoff Emergencies
14.1 EMERGENCY CATAPULT FLYAWAY
After catapult launch, several emergencies may cause the aircraft to settle, e.g., slow catapult, AB
blowout, degraded engine performance, single engine total loss of thrust, improper trim setting, etc. If
settling cannot be stopped immediately, it is necessary to eject without delay. Priorities during
emergency catapult flyaway are to establish control of the aircraft, arrest aircraft settle, and accelerate
for climbout.
If a settle is detected, the throttles should be advanced to MAX as soon as possible. If the thrust
output of one engine is degraded, some yaw and roll should be expected. If one engine is failed
completely, significant amounts of yaw and roll result with both throttles at MAX. In this worst case,
full rudder pedal and partial lateral stick may be required to oppose yaw/roll and maintain
lateral-directional control of the aircraft. Too much rudder pedal is not harmful, but too little rudder
pedal may cause controllability problems. Therefore, FULL rudder pedal to oppose yaw/roll is
prudent.
Proper AOA control is crucial to maintaining aircraft control and to arresting aircraft settle. AOA
must be high enough to minimize altitude loss yet low enough to maintain lateral-directional control.
During a nominal, two-engine catapult launch, the aircraft is trimmed to capture and maintain a
reference AOA of 12° (hands off). The FCS does allow small overshoots during initial flyaway, but peak
AOA should typically be below 13°. Catapult launch bulletins ensure an endspeed at least 15 knots
above minimum controllable airspeed (Vmc). Vmc numbers for the EA-18G launch bulletins are
defined at 14° AOA, which was selected as a compromise between arresting settle off the bow and
controllability. (Increased AOA helps arrest sink but also reduces lateral-directional controllability
resulting in higher minimum control speeds.) During single engine, MAX power catapult flyaway,
controllability should be sufficient if airspeed is above Vmc.
Under normal circumstances, proper AOA control should be provided by the FCS. However, certain
catapult failures (mis-trim, AOA probe splits or failures, FCS malfunctions) may require the pilot to
actively control flyaway pitch attitude/AOA. With an AOA malfunction, HUD displayed AOA may be
in error, so that pitch attitude becomes the only reliable source of AOA control. For this reason, the
recommended flyaway procedure is to maintain 10 to 12° pitch attitude with the waterline symbol
without exceeding 14° AOA (AOA tone). This should provide an AOA high enough to arrest the settle
yet low enough to retain lateral-directional control.
Depending on aircraft gross weight, stores jettison may be required to ensure a positive single engine
rate of climb (SEROC). Immediate jettison of excess weight minimizes altitude loss and, when
launching with a lateral weight asymmetry, returns the aircraft to a symmetric configuration,
potentially improving lateral-directional controllability.
It is also essential that the flaps remain in FULL until a positive rate of climb is established, as flap
retraction increases aircraft settle.
V-14-1
ORIGINAL
A1-E18GA-NFM-000
The first four steps in the procedure are the most important to arrest settle and maintain control of
the aircraft. Raising the LDG GEAR handle reduces drag and allows a greater rate of climb; however,
attention should not be diverted from maintaining aircraft control to perform this action. The landing
gear should only be raised when the first four immediate action steps have been accomplished,
controllability is not in question, and raising the gear does not compound the emergency.
NOTE
When the LDG GEAR handle is raised, the on-speed AOA bracket is
removed from the HUD.
If flyaway airspeed available -
*1. Throttles - MAX
*2. Rudder pedal - FULL AGAINST YAW/ROLL
*3. EMERG JETT button - PUSH
*4. Maintain 10° to 12° pitch attitude with W symbol.
• Do not exceed 14° AOA (AOA tone).
If unable to arrest yaw/roll or stop settle -
*5. EJECT
• Exceeding 10° to 12° pitch attitude may result in rapid loss of lateral
directional control.
• Raising flaps will increase aircraft settle.
14.2 ABORT
Maximum planned abort speed is dependent on ambient conditions, gross weight, runway length,
and runway and/or braking conditions. However, the decision to abort depends on the nature and
severity of the emergency.
Published maximum abort speeds for the existing conditions should allow the aircraft to be stopped
within the runway remaining without the use of long field arresting gear. For extreme emergencies, the
availability of long field arresting gear may influence the decision to abort. For other, less critical
emergencies, the decision to abort or continue the takeoff is crucial. Successfully stopping a heavy
weight aircraft on a high speed abort may prove to be a more extreme emergency than continuing a
V-14-2
ORIGINAL
A1-E18GA-NFM-000
takeoff with the given malfunction. No rule can be made to cover every situation, so good judgment and
common sense should be used. A thorough preflight briefing of abort contingencies should aid the pilot
in making a timely abort decision.
Once the decision to abort is made, the amount of runway remaining dictates braking technique and
the decision to take any long field gear. After brakes are applied, stabilator braking with up to full aft
stick is extremely effective in aiding deceleration. At heavy takeoff gross weight, excessive brake
heating, melted wheel assembly fuze plugs, and/or blown tires should be anticipated. If the long field
gear is required to stop the aircraft, inform the tower and/or other members of the flight as soon as
possible. Lower the hook in time for it to fully extend. If the aircraft cannot be stopped in the runway
remaining, the decision whether or not to eject must be made. If in doubt, eject prior to the aircraft
leaving the prepared surface.
*1. Throttles - IDLE
*2. Speedbrake - AS DESIRED
*3. Brakes - APPLY
*4. Stick - AFT below 100 knots (if required)
*5. HOOK handle - DOWN (if required)
NOTE
A rule of thumb to ensure full hook extension is 1,000 feet prior to the
arresting gear.
14.3 GO AROUND
Several emergency situations may require the use of the Go Around procedure: FIRE light on takeoff
(engine fire), loss of thrust on takeoff (engine failure), or loss of directional control on takeoff or
landing (NWS or blown tire). The decision to abort or execute a go around depends on the nature and
severity of the emergency. Refer to the preceding ABORT discussion.
For a loss of directional control on landing, the decision to execute a go around should not be
delayed. In most cases, it is better to go around immediately than struggle with directional control and
possibly depart the runway. An immediate go around allows time to assess the emergency and set up
for an arrested landing, if required.
The Go Around procedure provides a quick, simple way to safely get airborne if a situation arises
which requires immediate action. The use of MIL or MAX power depends on airspeed, runway
remaining, and aircraft configuration/asymmetry. If one engine fails, asymmetric thrust effects are
exacerbated at MAX power but are nonetheless controllable if AOA is maintained near on-speed.
When safely airborne, raising the landing gear, if HYD 2A is operative, improves acceleration and
climb; however, it may not always be prudent depending on the nature of the emergency.
V-14-3
ORIGINAL
A1-E18GA-NFM-000
With the FLAP switch in HALF, SEROC is normally sufficient at all gross weights and ambient
conditions. However, if the situation warrants, jettisoning excess weight increases SEROC and, if
asymmetric, returns the aircraft to a symmetric configuration, potentially improving lateral-directional
controllability. See figure 14-1, for the maximum weight and altitudes for 100 fpm SEROC.
1. Throttles - MIL or MAX
2. Maintain ON-SPEED AOA and balanced flight.
3. EMERG JETT button - PUSH (if required)
When single engine with the operating engine at MAX, the possibility of
an adverse yaw departure increases as AOA exceeds on-speed.
14.4 LOSS OF DIRECTIONAL CONTROL DURING TAKEOFF OR LANDING (BLOWN TIRE, NWS
FAILURE)
A directional control problem on takeoff or landing may be caused by a NWS, brake, landing gear
component failure, planing link failure or a blown tire. Directional control problems may be
compounded by wet or icy runways, crosswinds, hydroplaning, high lateral weight asymmetries, or
single-engine operations. It may be difficult to identify the source of the problem, and time is usually
critical. The decision whether to continue a takeoff or to abort, or on landing, to continue rollout
depends on the speed at the time the directional control problem is detected, the stopping distance
required, and the availability of arresting gear.
Loss of brakes may be caused by a brake or anti-skid system failure. A brake system failure may
cause a locked brake and/or blown tire, resulting in ineffective braking and/or loss of directional
control. A blown tire may cause engine FOD or flap and gear door damage. If decision to stop is made,
the primary danger is loss of directional control. For Planing Link Failure Procedures, refer to chapter
16.
If the decision to takeoff is made, nose rotation and/or takeoff may be
delayed by abnormal aircraft attitudes due to failures, increased drag,
and lack of or reduced rudder toe due to rudder deflection to counter
directional motion.
If detected after touchdown and flyaway airspeed available -
*1. Go Around

CHAPTER 15
Inflight Emergencies
15.1 AFTERBURNER FAILURE
Afterburner failure can be recognized by failure of the nozzle to open, which may be the only
symptom that is immediately recognizable. The afterburner receives continuous ignition any time the
throttle is above the MIL detent and afterburner lightoff is not yet detected. If an afterburner does not
light after selection or blows out, reduce the throttle to MIL and reselect afterburner. If an afterburner
fails to light on subsequent attempts, maintenance action is most likely required.
15.2 RESTART
Ignition is activated automatically whenever a flameout is sensed and the throttle is at or above IDLE. At
least 350 KCAS is required to maintain 12% rpm for a windmill airstart. When single engine, the hydraulic
system switches from 3,000 to 5,000 psi output pressure above approximately 500 KCAS/1.0 IMN (see figure
15-2). This results in additional horsepower extraction and reduced windmill rpm. The hydraulic system
output drops from 5,000 to 3,000 psi at approximately 480 KCAS/0.95 IMN. Therefore, maintain airspeed
below 480 KCAS/0.95 IMN to maximize the chance of a successful windmill restart.
Continuing automatic restart attempts at high altitude or high AOA may cause the engine to
overtemp. In this case, place the throttle OFF until in a better start environment. The optimum restart
envelope is below 25,000 feet. If the engine is shut down from a high power setting and rpm decays to
0%, temporary rotor binding may occur. In this case, engine rotation will not be regained until the
engine cools evenly (about 10 to 15 minutes). Windmill restart attempts made after rpm has degraded
to 0% may require up to 450 knots to obtain 12% rpm for ignition.
APU restart is the last alternative. If APU restart is required, HYD ISOL ORIDE should first be
selected for 10 seconds prior to APU start, assuming good HYD 2B. With the APU switch ON, and the
green READY light on, the engine crank switch may be used to crank the engine for restart. The APU
restart envelope is below 250 KCAS, below 10,000 ft. See figures 15-1 through 15-4.
Attempting to restart an engine that has flamed out for no apparent
reason may result in an engine bay fuel leak/fire.
If rpm above 30% -
1. Throttle affected engine - IDLE or above
If rpm below 30% -
1. Throttle good engine - 80% N2 rpm minimum.
2. ENG CRANK switch - L or R (affected side)
3. Throttle affected engine - IDLE or above
4. Monitor EGT during start (871°C maximum). FADEC will not prevent hot starts airborne.

15.3 FUSELAGE FUEL LEAK
The possibility of fire is normally of prime concern with any fuel leak; however, with a massive leak,
the fuel loss itself must be dealt with promptly and correctly to ensure that sufficient fuel remains to
return to base. Fuel loss rates can be in excess of 1,000 ppm from failed main fuel lines. Left unchecked,
this leak can rapidly drain external tanks, both transfer tanks, and the feed tank on the leaking side.
Since leaks may occur upstream of the throttle-operated fuel shutoff valve in the fuel control, shutting
down the throttle may not stop the leak. Pressing the corresponding FIRE light closes the feed tank
fuel shutoff valve for that engine and stops fuel flow through the main fuel line.
The pilot may not be able to visually determine which side is leaking. Utilize a wingman, when
available, and check for secondary indications to determine the side of the leak. In addition to the
primary cockpit indications listed in the procedure, the following may also be indications of a fuselage
fuel leak: FUEL LO caution, erratic engine operation at high power settings, abnormal fuel flow
indications.
1. Afterburners - DESELECT
Afterburner operation with a fuselage fuel leak may result in a fire.
2. Analyze indications to determine which side is leaking:
• Visual confirmation of fuel leakage
• L or R BOOST LO caution
• FEED tank imbalance (lower feed tank)
• FUEL LO caution (lower feed tank)
• Erratic engine operation
If unable to confirm side -
3. Land as soon as possible.
If side confirmed -
3. Throttle affected engine - OFF
4. FIRE light affected engine - PUSH
Securing the good engine may result in flameout of both engines.
If fuel leak stops -
5. Land as soon as practical.
If fuel leak continues -
6. Land as soon as possible.
V-15-4
ORIGINAL
A1-E18GA-NFM-000
FOR LANDING (leak continues) -
1. Make normal vice arrested landing (if possible).
2. Use light braking.
After landing-
3. Turn aircraft into the wind.
4. Throttles - OFF
5. FIRE lights - PUSH
15.4 HYDRAULIC FAILURES
Hydraulic failures are indicated by the HYD 1A, 1B, 2A, and 2B circuit cautions described in
Chapter 12. The effects of losing one or more HYD circuits can be seen by analyzing the Hydraulic
Flow Diagram shown in figure 15-5. For multiple hydraulic circuit failures, the Hydraulic Subsystems
Malfunction Guide (figure 15-6) shows which flight control surfaces are lost.

DOUBLE TRANSFORMER-RECTIFIER FAILURE
Failure of both transformer-rectifiers (TRs) can be recognized by loss of the HUD (but not the other
displays), bleed air including cockpit airflow/pressurization, and other equipment which operates on
the main dc busses. The FCC channels continue to be powered by their respective PMG outputs. The
Essential Bus is powered by the EBB PMGs with the battery charger and the battery as backups.
Therefore, the battery gauge should read greater than 24 vdc (26.5 nominal) and the BATT SW caution
light should be out.
With a dual TR failure, time is not critical, and essential bus equipment need not be turned off.
Equipment requiring ac power only will remain operable with a dual TR failure and need not be turned
off to conserve battery power. If the L or R DC FAIL caution lights illuminate, all three 28 volt dc
windings from the corresponding PMG are prevented from supplying FCC CH or essential bus backup
power. See the Emergency Power Distribution Charts (figure 15-7) for operative and inoperative
equipment.
1. BATT SW caution light - CONFIRM OUT
2. Electrical RESET button - PRESS
3. Maintain airspeed below 325 KCAS (300 to 325 KCAS optimum).
4. ECS MODE switch - OFF/RAM
5. AV COOL switch - EMERG
6. CABIN PRESS switch - RAM/DUMP
7. OBOGS control switch - OFF
8. Maintain altitude below 10,000 feet MSL prior to emergency oxygen depletion (10 to 20 minutes).
9. Consider removing mask and resetting emergency oxygen system once below 10,000 feet MSL.
10. Land as soon as practical.
If AV AIR HOT caution appears -
11. Non-essential avionics equipment - OFF (e.g., radar, UFCD controlled avionics, ECM,
sensors, MC2)
12. Land as soon as possible.
For landing -
13. Perform Landing Gear Emergency Extension Procedure.
14. Make a short field arrestment (if available).
15. Use emergency brakes with steady brake pressure. (Anti-skid is not available.)

15.6 COCKPIT TEMPERATURE HIGH
Hot cockpit airflow may be caused by an ECS control failure or a valve failure. Selecting full COLD
on the CABIN TEMP knob should shut off warm air to the cockpit. If this procedure fails to secure
warm air to the cockpit, then the failure is most likely with the cockpit flow valve itself. If this is the
case, securing both BLEEDS may be the only means to stop the flow of warm air.
Selection of MAN with the ECS MODE switch is prohibited. Selection of
MAN while the aft cooling fan shutoff valve is open may cause the fan to
overspeed resulting in a catastrophic fan failure potentially leading to loss
of OBOGS.
In ECS MAN mode, cockpit temperature can reach 190°F, if the cockpit
flow valve is stuck full open.
1. CABIN TEMP knob - FULL COLD
If temperature still high -
2. Maintain altitude below 25,000 feet.
3. CABIN PRESS switch - RAM/DUMP

15. Land as soon as possible.
15.7 COCKPIT SMOKE, FUMES, OR FIRE
Consider all unidentified fumes in the cockpit as toxic. Do not confuse condensation from the ECS.
The most probable source of visible smoke or fumes in the cockpit is from the engine bleed air or
residual oil in the ECS ducts. This smoke is blue gray in color, has a characteristic pungent odor, and
may cause the eyes to sting. Another source of smoke or fumes is an electrical malfunction or overheat
of equipment located in the cockpit. In the event of an electrical short or overload condition, this
equipment may generate electrical smoke (usually white or gray in color) but should not cause an open
fire since cockpit equipment uses very little electrical current. Cockpit electrical wiring insulation may
smolder and create smoke, but will not erupt into a seriously damaging fire.

15.10 DISPLAY MALFUNCTION
If a display malfunctions (stale data or DDI pushbuttons do not work), attempt to restore by cycling
display power. If cycling power to the display does not fix the problem, cycling the corresponding
mission computer may restore the DDI (cycle MC1 for LDDI, MC2 for RDDI). HUD symbology is
driven by either MC1 or MC2. If the UFCD malfunctions, attempt to restore by cycling the MPCD or
8 x 10 display.
If all displays are flashing STANDBY, and a backup HUD is displayed in the front cockpit, a dual
MC failure has occurred.
15.11 DUAL MISSION COMPUTER (MC) FAILURE
A dual MC failure is recognized by STANDBY flashing on the HUD and L/RDDIs. In the front
cockpit, a backup HUD format (driven by the SDC) is displayed on the MPCD and UFCD. After
cycling an MC, the corresponding display (LDDI for MC1, RDDI for MC2) continues to flash
STANDBY for approximately 11 seconds while the MC boots up.

15.12 OCF - OUT-OF-CONTROL FLIGHT
Selection of manual spin recovery mode (SPIN switch in RCVY) seri-
ously degrades controllability, will prevent recovery from any departure
or spin, and is prohibited.
15.12.1 Departure from Controlled Flight. A typical departure occurs as a yaw divergence (nose-
slice) followed by an uncommanded roll in the same direction. The yaw divergence can happen very
quickly; therefore, the yaw rate tone may not provide sufficient departure warning. Usually, a
departure is preceded by a slow buildup in sideslip and uncomfortable sideforces. The buildup of
sideslip is accompanied by ″vortex rumble″; however, vortex rumble may not be noticed during
aggressive maneuvering. Therefore, excessive sideforce provides the most reliable departure warning
cue to the pilot. The initial phase of the departure is not particularly violent or disorienting unless it
occurs at high airspeed or Mach number. Recognition of these cues permits neutralization of the
controls and avoidance of a departure.
15.12.1.1 Departures with Lateral Weight Asymmetries. Complying with NATOPS limits for
asymmetric store loadings is required to prevent departures. Aggressive longitudinal maneuvering
beyond NATOPS AOA limits may result in a yaw departure away from the heavy wing, which cannot
be controlled with lateral stick or pedal inputs. At low airspeed, recovery is immediate when AOA is
reduced below NATOPS limits. At higher airspeed, more violent and sudden departures may occur
with little or no warning when maneuvering aggressively beyond NATOPS limits. In such cases, the
resulting post-stall gyrations rapidly transition to an upright spin away from the heavy wing.
15.12.1.2 Departure Recovery. Recovery is generally very prompt, on release of the controls. Some
departures, particularly from inadvertent tailslides, may exhibit large transitory sideslips or negative
g rolls prior to positive recovery. Sideslip type departures yield excessive gravity-induced sideslip at
relatively slow airspeeds (<90 KCAS) and can quickly develop into a spin. In the absence of a steady
spin arrow, controls should remain neutral throughout all such post departure motion, as CAS reliably
regains control. Any pilot input will delay recovery or precipitate further departure. For departure
recoveries that stabilize in a negative g stall, application of aft stick may be used to finish the recovery.
15.12.2 Spin. Spin is confirmed by a steady spin arrow or the presence of a sustained yaw rate,
elevated positive or negative AOA, and airspeed less than 150 KCAS. Spin arrows very reliably indicate
the appropriate recovery action. While some departures may generate sufficient yaw rate to trip the
command arrow, they are typically self-recovering by the time the arrow is displayed, and the arrow
will quickly disappear. Therefore, with the spin arrow present, a brief hesitation is all that is required
to confirm a steady, valid arrow prior to applying anti-spin lateral stick.
15.12.2.1 Spin Recovery. The command arrow indicates the proper control stick position for
upright or inverted spins. For upright spins, the command arrow directs the pilot to apply full lateral
stick with the spin direction. For inverted spins, the command arrow directs the pilot to apply full
V-15-17
ORIGINAL
A1-E18GA-NFM-000
lateral stick opposite the spin direction. In general, spin recovery is straightforward and reliable if the
OCF procedures are followed and sufficient altitude remains. For lateral weight asymmetry loadings,
recoveries from upright spins away from the heavy wing are essentially identical to the symmetrical
loaded airplane. Spin recoveries for less common upright spins into the heavy wing, and inverted spins,
were sometimes delayed due to the oscillatory nature of the spin. Recovery begins immediately but
may take up to one turn to become apparent. Recovery from a fully developed spin may include high
roll rates with significant negative g unloads, which, though disorienting and uncomfortable, should be
interpreted as a positive indication of imminent recovery. When the command arrow is removed,
lateral stick should be smoothly returned to neutral. Maintaining anti-spin lateral stick after the
command arrow has disappeared may transition the recovering spin into a controllable roll that could
delay recovery.

*1. Controls - RELEASE, FEET OFF RUDDERS, SPEEDBRAKE IN
If still out of control -
*2. Throttles - IDLE
*3. Altitude, AOA, airspeed, and yaw rate - CHECK

*5. Lateral stick - SMOOTHLY NEUTRAL
When recovery indicated by AOA and yaw rate tones removed, side forces subsided, and
airspeed accelerating above 180 knots -
*6. Recover.
Failure to ensure all criteria are met may result in departure during
recovery.
Passing 6,000 ft AGL, dive recovery not initiated -
*7. Eject.
Post departure dive recovery initiated below 6,000 ft AGL is not assured.
Delaying the ejection decision below 6,000 ft AGL while departed may
result in unsuccessful ejection.
