Landing Gear Emergency Extension
Steps 1-5
- Airspeed - REDUCE TO 150 KIAS OR BELOW
- Gear handle - DOWN
- EMER LDG GR handle - PULL
- Landing gear down indicator lights - CHECK
- Flaps - AS REQUIRED
…
Airstart Envelope
Warning (1W)
SL - 15,000 feet: 125-200 KIAS
15,001-20,000 feet: 135-200 KIAS
Compressor Stalls
- PCL - SLOWLY RETARD BELOW STALL THRESHOLD
- DEFOG switch - ON
- PCL - SLOWLY ADVANCE (AS REQUIRED)
If power sufficient for continued flight:
4. PEL - EXECUTE
If Power inefficient to complete PEL:
5. PCL - OFF
6. FIREWALL SHUTOFF handle - PULL
7. Execute Forced Landing or Eject
Runaway Trim
Steps 1-4 & Note 1 (1N)
- Trim interrupt button (control stick) - DEPRESS AND HOLD
- Airspeed - AS REQUIRED TO REDUCE CONTROL FORCES (1N)
- TRIM DISCONNECT switch (left console) - TRIM DISCONNECT
- Trim interrupt button (control stick) - RELEASE
…
[1N] Except when trim is at full nose down, reducing airspeed to 110-150 KIAS will reduce control forces. Adding power will cause a pitch up/left yaw, while reducing power will cause a pitch down/right yaw. With full nose down trim, cruise and approach as fast as practical to reduce pitch forces.
Emergency Ground Egress
- ISS mode selector - SOLO
- Seat safety pin - INSTALL
- PARKING BRAKE - AS REQUIRED
- Canopy - OPEN
If canopy cannon be opened or situation requires right side egress: - CFS handle safety pin - REMOVE (BOTH)
- CFS handle - ROTATE 90° COUNTER CLOCKWISE AND PULL (BOTH)
- Shoulder straps, lap belt, SSK fittings, and leg restraint garters - RELEASE (BOTH)
- BAT, GEN, and AUX BAT switches - OFF
- Evacuate aircraft
Canopy Unlocked
Steps 1-3 & Warnings 1W & 2W
- Airspeed - 150 KIAS MAXIMUM; AVOID ABRUPT MANEUVERING [1W]
- Descend below 18,000 MSL
- PRESSURUZATION switch - DUMP BELOW 18,000 FT MSL
- Land as soon as possible
[1W] Do not attempt to lock the canopy in flight. Movement of the internal canopy lock handle may inadvertently allow the canopy to open and depart the aircraft.
[2W] If canopy from is floating off the left side rail or the canopy is obviously unlocked, do not eject.
Departing Controlled Flight
All Warnings, Notes, Cautions
[1W] Improperly positioning the control stick/elevator aft of the neutral position may significantly delay or prevent the aircraft from recovering from an OCF/spin which could result in loss of aircraft and/or crew.
[2N] Cycling of control positions or applying anti-spin controls prematurely can aggravate aircraft motion and significantly delay recovery.
[3W] Recommended minimum altitude for ejection is 6000 feet AGL.
[4C] Power-on and inverted departures or spins will result in high loads on the engine and torque shaft. If encountered, land as soon as conditions permit. Suspect possible engine damage and may experience unusual engine operation accompanied by low oil pressure or CHIP annunciator illumination. Engine shall be inspected by Mx after flight.
