Question 16

APU limitations

Answer 16

Do not operate the APU below -1000 feet pressure altitude.
-The APU may be used to supply bleed air to air conditioning pack number 2 for takeoff, provided isolation valves remain closed.
-Do not use APU generator power inflight.
Operation between 15,000 feet and 20,000 feet pressure altitude is limited to “no load” only.
-APU bleed air should not be used above 15,000 feet pressure altitude.

Answer 19

50 feet
below minimums unless it is coupled to an ILS glideslope and localizer or in the
go–around mode.

100 feet RA.

Question 21

Do not use FLCH on final approach below

Answer 21

1,000 feet AFE.

Question 22

Intentional selection of reverse thrust in flight is

Answer 26

prohibited

Question 27

Backing the airplane with use of reverse thrust is

Answer 27

prohibited.

Question 28

Flight controls caution/limitations

Answer 28

Avoid rapid and large alternating control inputs, especially in combination with
large changes in pitch, roll, or yaw (e.g., large side slip angles) as they may result
in structural failure at any speed, including below VA.

If leveling off within 2000 feet after changing altimeter setting from QNE to QNH,
or QNH to QNE, do not use VNAV to execute the level-off if QNH is less than
29.70 IN/1006 hPa. After the level-off is complete, VNAV may be re-engaged.
