OTHER CONSIDERATIONS:

1

 Hot start - FTIT over 800

_

C. During engine start, if the FTIT

increases at an abnormally rapid rate through 750

_

C, a hot

start can be anticipated.

2

 Motor engine with JFS until FTIT reaches 200

OTHER CONSIDERATIONS:

1

 An engine or JFS fire/overheat can be detected by flames,

smoke, explosion, signal from ground crew, or radio call. FTIT

may exceed 800°C and, if ac power is available, ENG FIRE

warning or OVERHEAT caution light may illuminate.

C12/PW

OTHER CONSIDERATIONS:

1

 The chances for a successful AB light with the nozzle open

more than 30 percent are reduced.

2

W

 With nozzle loss, catastrophic engine failure and fire are

probable with prolonged high power settings above 850

_

C

FTIT while in SEC.

3

 In a partial thrust situation, thrust available may increase as

altitude decreases. 250 kts approximates the airspeed at which

thrust required for level flight is the lowest.

4

F

With a missing nozzle, level flight may not be attainable

above 5000 ft MSL.

F

If descent is required, maintain 250 kts with throttle set at

850

AB MALFUNCTION ON TAKEOFF

If decision is made to stop:

1. Abort.

If takeoff is continued:

1. Throttle - MIL.

2. Stores - Jettison (if required).

LOW THRUST ON TAKEOFF OR AT LOW ALTITUDE

(NONAB)

If on takeoff and the decision is made to stop:

1. Abort.

If takeoff is continued and/or thrust is insufficient:

1. Throttle - AB.

3. Stores - Jettison (if required).

If nozzle is failed open, damaged, or missing:

4. Airspeed - Climb to arrive at 250 kts or descend

at 250 kts to obtain level flight above min

recommended ejection altitude or min safe

altitude, whichever is appropriate.

 If airspeed drops below 250 kts, trade altitude to

reacquire 250 kts. Do not descend below min recommended

OTHER CONSIDERATIONS:

1

Maintain takeoff thrust until min recommended ejection

altitude is attained and then throttle to min practical.

2

If fire occurred in AB, ENG FIRE warning light may not

illuminate. Fire should extinguish after throttle is retarded;

however, nozzle damage may result in lower than normal

thrust.

3

Determine if fire detection circuit is functional.

OTHER CONSIDERATIONS:

1

 If the OVERHEAT caution light goes off, verify the integrity

of the detection circuit by depressing the FIRE & OHEAT DETECT

button and land as soon as possible.

2

 Determine if fire detection circuit is functional.

3

 If the EPU was manually turned on, consider turning it off to

determine if it is the source of the overheat condition. If the

OVERHEAT caution light remains on, the EPU should be turned

back on.

4

 External fuel cannot be transferred in OFF or RAM. Consider

jettisoning tanks to decrease drag if range is critical and the

ECS cannot be turned on for short periods of time to transfer

fuel.

5

W

F

With the ECS shut down or the AIR SOURCE knob in

OFF or RAM, the gsuit does not inflate and PBG is disabled.

F

With the AIR SOURCE knob in OFF or RAM, OBOGS is

inoperative. Activate EOS if OXY LOW warning light illuminates

above 10,000 ft cockpit altitude.

6

 If in VMC and the ADI and HSI are not required for flight, the

EGI should be considered nonessential.

7

W

 If LG handle does not lower, select BRAKES CHAN 2 and

position ALT FLAPS sw to EXTEND. Nozzle remains closed,

resulting in higher than normal landing thrust.
