Limits Part Deux

Question 1

What is the N _r range to avoid prolonged APU use and why?

Answer 1

94-96% because the APU clutch will oscillate from engaged to disengaged. This creates high loads.

Question 2

When is APU operation prohibited?

Answer 2

During normal flight

Question 3

What is the APU caution that should be observed after an aborted start or fault?

Answer 3

Wait 30 seconds after APU has stopped before attempting restart. After 2 consecutive start attempts, wait 20 minutes before third attempt. No more than 3 attempts an hour.

Question 4

What shall be observed after 30 minutes of ground operation with the APU on?

Answer 4

Observe XMSN TEMP 1 & 2 on the SYS page. If exceeding 140C the APU shall be shut down to cool XMSN fluid for 30 min prior to resuming APU grnd ops, or fluid may be cooled by operating at least 1 engine with rotor turning.
