Q

More regarding APU DET INOP light fails to illuminate

A

Do not operate the APU if the APU DET INOP light fails to illuminate.
-From ‘A1-P8AAA-NFM-000,’ page 438

17
Q

Note regarding conducting APU fire detector test.

A

fire
-From ‘A1-P8AAA-NFM-000,’ page 438

18
Q

Note regarding APU RUNNING light fails to illuminate by end of the start cycle

A

If the start fails or the APU RUNNING light fails to illuminate by the end of the start cycle, a system failure has occurred and the FAULT light illuminates.
-From ‘A1-P8AAA-NFM-000,’ page 439

19
Q

Note regarding what happens when the APU EGT stabilizes

A

When the APU EGT stabilizes the APU RUNNING light illuminates
and the APU GEN OFF light extinguishes.
-From ‘A1-P8AAA-NFM-000,’ page 439

20
Q

Note regarding how long the APU SHOULD be run prior to bleed air use

A

The APU should be operated for 1 minute prior to being used as a bleed
air source.
