### For engine restart, turbine inlet temperature must be below what temperature?

• A.

400C

• B.

150-250C

• C.

200-400C

• D.

200C and 100C if using enrichment

D. 200C and 100C if using enrichment
Explanation
The correct answer is 200C and 100C if using enrichment. This means that for an engine restart, the turbine inlet temperature must be below 200C. However, if enrichment is being used, the temperature must be below 100C. Enrichment refers to the process of adding extra fuel to the engine to increase its power output. Therefore, if enrichment is being used, the temperature threshold for engine restart is lower.

• B.

LOPAC, Huffer cart, lox cart

• C.

External, APU, engine

• D.

All of the above

C. External, APU, engine
Explanation
The answer "External, APU, engine" correctly identifies the three sources of bleed air. Bleed air is extracted from the compressor stages of the aircraft's engines, the auxiliary power unit (APU), and from external sources such as ground power units or air conditioning units. These sources provide the necessary compressed air for various aircraft systems, including cabin pressurization, air conditioning, and engine starting.

Rate this question:

### What is the RPM range of low speed ground idle (LSGI)?

• A.

92.5-100.5%

• B.

96-106%

• C.

69-75.5%

• D.

None of the above

C. 69-75.5%
Explanation
The correct answer is 69-75.5%. This range represents the RPM (Rotations Per Minute) range of low speed ground idle (LSGI). LSGI is a mode in which the engine operates at a lower RPM while the aircraft is on the ground, typically during taxiing or when the aircraft is stationary. This range ensures that the engine runs at an appropriate speed for ground operations, providing sufficient power without causing excessive wear or fuel consumption.

### What is the maximum allowable oil pressure in the power section during starting and warm-up?

• A.

60-85psi

• B.

50-60psi

• C.

250psi

• D.

50-100psi

D. 50-100psi
Explanation
During starting and warm-up, the maximum allowable oil pressure in the power section is between 50-100psi. This range ensures that the oil pressure is sufficient to lubricate the engine components and provide proper functioning without causing any damage or excessive wear. It allows for a gradual increase in oil pressure as the engine warms up, ensuring smooth operation and preventing any potential issues that could arise from low or high oil pressure.

Rate this question:

• 23.

### What is the Utility and Booster hydraulic system pre-loads

• A.

2900psi

• B.

1000psi +or- 100psi

• C.

300psi +or- 100psi

• D.

1500psi +or- 100psi

D. 1500psi +or- 100psi
Explanation
The utility and booster hydraulic system pre-loads are set at 1500psi with a tolerance of plus or minus 100psi. This means that the system is designed to operate at a pressure of 1500psi, but it can fluctuate within a range of 100psi higher or lower than that value. This allows for some flexibility in the system's performance while still maintaining a relatively consistent pressure level.

Rate this question:

• 24.

### During normal operation, the APU generator will power what electrical bus?

• A.

Only left

• B.

Only right

• C.

Only essential

• D.

Only main

C. Only essential
Explanation
The APU generator will power only the essential electrical bus during normal operation. This means that it will provide power to the systems that are necessary for the safe operation of the aircraft, such as critical instruments, essential lighting, and communication systems. The left, right, and main electrical buses are not powered by the APU generator in this scenario.

Rate this question:

• 25.

### If the start valve light does not illuminate within 5 seconds during starting what action should be taken?

• A.

Condition lever feather

• B.

Discontinue start

• C.

Discharge fire agent

• D.

Evacuate the aircraft

B. Discontinue start
Explanation
If the start valve light does not illuminate within 5 seconds during starting, the correct action to be taken is to discontinue the start. This is because the start valve light indicates that the start valve is open and fuel is being introduced into the engine. If the light does not illuminate, it suggests a potential issue with the start valve or fuel flow, and continuing the start could lead to further complications or damage to the engine. Therefore, it is necessary to discontinue the start to prevent any potential risks or damages.

Rate this question:

• 26.

### What is the APU starter duty cycle?

• A.

1 min on, 5 min off

• B.

1 min on, 4 min off

• C.

1 min on, 30 min off

• D.

1on 1 off, 1on 5 off, 1on 30 off

B. 1 min on, 4 min off
Explanation
The APU starter duty cycle refers to the amount of time the APU starter is operated and the amount of time it is allowed to rest. In this case, the correct answer is "1 min on, 4 min off," which means that the APU starter is operated for 1 minute and then allowed to rest for 4 minutes before it can be operated again. This duty cycle helps prevent overheating and allows the starter to cool down between cycles, ensuring its proper functioning and longevity.

Rate this question:

• 27.

### During starting, the APU should indicate

• A.

98-102%

• B.

98-102% within 60 seconds

100% +or- 2% within 35 seconds

• D.

100% +or- 5% within 15 seconds

C. 100% +or- 2% within 35 seconds
Explanation
The correct answer is 100% +or- 2% within 35 seconds. This means that during starting, the APU (Auxiliary Power Unit) should reach a speed of 100% with an acceptable deviation of plus or minus 2% within 35 seconds. This indicates that the APU is starting up efficiently and functioning properly within the specified time frame and speed range.

• D.

30psi to 15psi in less than 16 seconds

B. 30psi to 15psi in no less than 16 seconds
Explanation
The bleed air bleed down check limitations refer to the rate at which the pressure in the system decreases. The correct answer states that the pressure should go from 30psi to 15psi in no less than 16 seconds. This means that the pressure should not decrease faster than 30psi to 15psi in 16 seconds, indicating a specific time frame for the bleed down process.

### During normal operation, the APU EGT (exhaust gas temperature) should not exceed what temperature?

• A.

400C

• B.

600-610C

• C.

680C

• D.

None of the above

C. 680C
