Answer 14

10,000 ft = APU bleed + electrical
17,000 ft = APU bleed
41,000 ft = Electrical

Although, not recommended for operations above 25,000 ft

Question 15

Answer 15

1. APU low oil pressure (light)
2. APU Fault (light)
3. APU overspeed (light)
4. APU Fire
5. DC Battery Switch to off

Question 16

APU Starts (2 concerns)

Answer 16

1. Wait 2 minutes for the bleed air
2. After 3 start attempts, give it a 15 minute cooling period

Question 17

Fuel Tank Capacities

Answer 17

L/R mains: 8,630 lbs
Center: 28,803 lbs
Total: 46,063 lbs

Question 18

Fuel loading concern regarding center tank?

Answer 18

If the center tank has more than 1,000 lbs, the main tanks must be full.

Question 19

Fuel Temp limits

Answer 19

Max fuel temp: 49c
Min tank fuel temp limit: -43c or 3c above (-40) fuel freezing point temp whichever is higher.

Example: the freezing point of JP-8 is -47c. So if the tank fuel was -44c it still wouldn’t be warm enough.
