Answer 26

APU bleed valve may be open during engine start, but avoid engine power above idle.

Question 27

When must the APU bleed valve be closed?

Answer 27

Except for engine start, the APU bleed valve must be closed when another source is pressurizing the left bleed air duct.

Question 28

Maximum flap extension altitude is

Answer 28

20,000 ft. (AFM)

Question 29

What configuration should the airplane be in when holding in icing conditions?

Answer 29

Clean. Holding in icing conditions with flaps extended is prohibited. (AFM)

Question 30

What is the lowest altitude that speed brakes may be used in flight?

Answer 30

Do not deploy speed brakes in flight below 1000 ft AGL.

Question 31

When using the SPEED BRAKE inflight what is the maximum detent position?

Answer 31

In flight, do not extend the SPEED BRAKE lever beyond the FLIGHT DETENT. (AFM)

Question 32

What is the maximum Flap position for speed brake use?

Answer 32

Do not deploy speed brakes with more than Flaps 10 extended.* * Although not prohibited, the use of speedbrakes with Flaps 1-10 extended should be avoided as much as possible. The use of speedbrakes with flaps extended increases loads on the trailing edge flaps, resulting in increased wear and tear.
