Q

When should the engine be manually aborted?

A

a. ITT increasing & likely to exceed 1,000°C (hot)
b. Normal N1 increase is halted (hung)
c. No rise of ITT is evident within 10 seconds (no start)
d. BAT BUS annunciator illuminates during start sequence
e. ST READY annunciator extinguishes

2
Q

Can you attempt a restart if an external power engine start was attempted?

A

NO

3
Q

When does Emergency Engine Shutdown on the Ground boldface apply?

A

Engine fire, prop strike, chip light, likely to depart prepared surface, FF >800, any other serious emergency

4
Q

After a stop that involved max braking, should you set the parking brake?

A

No

5
Q

N1 does not indicate speeds below _____. It will indicate 0%.

A

8%

6
Q

What annunciators will illuminate with an engine failure in flight?

A

GEN, FUEL PX, OIL PX, OBOGS FAIL

7
Q

What is the zoom capability at 200 knots? 250 knots?

A

600’ to 900’ ft; 1170’ to 1550’ ft

8
Q

How much additional altitude will the zoom to EJECT attain?

A

200’

9
Q

How long and how much altitude approx. will you lose for an immediate airstart?

A

40 seconds, 1,200’ ft @ 125 KIAS

10
Q

What is the airstart envelope?

A

125-200 KIAS for sea level-15,000’ft

135-200 KIAS for 15,001’ft-20,000’ft

11
Q

Movement of the PCL above IDL before N1 stabilizes at approx. ___% will cause an increase in fuel flow, which may cause engine failure.

A

67%

12
Q

If the start switch is left in MANUAL, it will drain the battery in ___ minutes.

A

10 minutes

13
Q

True/False: The propeller will unfeather and accelerate to operating RPM approximately 20 seconds after N1 reaches 45%.

A

TRUE

14
Q

1Opening the PROP SYS circuit breaker will remove power from the feather dump solenoid and allow oil pressure to return, which brings the prop out of fully feather state in ___ to ____ seconds

A

15 to 20 seconds

15
Q

What are indications of a prop feather?

A

High torque, prop noise, loss of thrust, engine vibrations

16
Q

What are indications of a prop sleeve touchdown? What annunciators normally occurs?

A

Fluctuations in Np, torque increasing, thrust decreasing, engine vibrations
b. CHIP light

17
Q

If the PMU SWITCH is placed OFF, what happens to ground idle N1?

A

It will not be available, expect 67% N1

18
Q

With constant torque & airspeed, when is RPM considered stable below 40% Np?

A

3 seconds

19
Q

At 125 KIAS, 4-6% torque, what should your rate of descent be?

A

1350-1500 fpm

20
Q

With the PROP SYS circuit breaker pulled & PMU SWITCH OFF, what happens to the feather dump solenoid?

A

It will not be powered & the prop will feather at a very slow rate

21
Q

What check is initiated if a suspected fire occurs in flight?

A

FEVER

22
Q

Will OBOGS be operable with battery failure?

A

No, it is tied to the Hot battery bus

23
Q
