Q

Auxiliary Power Unit (APU) Operating Limits:

APU Clutch Limitation

A

Avoid prolonged operation at 94% - 96% Nr with the APU running. The APU clutch will oscillate from engaged to disengaged. This creates high loads on the clutch and shall be avoided.

Q

Auxiliary Power Unit (APU) Operating Limits:

Use in flight?

A

APU operation is prohibited during normal flight.

17
Q

Auxiliary Power Unit (APU) Operating Limits:

APU Start Limitations

A

After a fault or aborted start, wait 30 seconds after APU has stopped before attempting another start. After 2 consecutive start attempts, wait 20 minutes before third start attempt. No more than 3 start attempts are permitted in one hour.

18
Q

Auxiliary Power Unit (APU) Operating Limits:

APU XMSN TEMP 1 and XMSN TEMP 2 Limit

A

If the temperatures exceed 140*C, the APU shall be shutdown and the transmission fluid allowed to cool for 30 minutes prior to resuming APU Ground operations; or transmission fluid may be cooled by operating an engine with rotor turning.
