Q

When must the ENGINE START switches be in the CONT position?

A

ENGINE START switches must be in the CONT position for:
• Takeoff
• Landing
• Anti-ice operation
• Operation in hail, sleet or moderate to heavy rain

18
Q

When must the ENGINE START switches must be in the FLT position?

A

ENGINE START switches must be in the FLT position for:

• Operation in severe turbulence

19
Q

Minimum Oil Temperature before setting takeoff thrust

A

737MAX = 31°C

No temp limitation for 737NG

20
Q

Can you select reverse thrust in flight?

A

Intentional selection of reverse thrust in flight is prohibited.

21
Q

APU LOAD limits:

Bleed and Electric Load

A

10,000

22
Q

APU LOAD limits:

Bleed Only

A

17,000

23
Q

APU LOAD limits:

Electric Only

A

41,000

24
Q

APU LOAD limits:

Maximum Operating Altitude

A

41,000

25
Q

How many minutes should the APU BLEED air switch be closed after start and before shutdown?

A

Ensure APU BLEED air switch is closed for 2 minutes after start and for 1 minute prior to shutdown.

NOTE: When the APU switch is moved to OFF, this time delay is met automatically.

26
Q

With the APU bleed valve open during engine start avoid what?

A

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

27
Q

When must the APU bleed valve be closed?

A

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

28
Q

Maximum flap extension altitude is

A

20,000 ft. (AFM)

29
Q

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

A

Clean.

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

30
Q

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

A

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

31
Q

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

A

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

32
Q

What is the maximum Flap position for speed brake use?

A

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.
33
Q

In the 700W and 900ER should you manually override the Load Alleviation System?

A

Manually overriding the Load Alleviation System is not authorized.

34
Q

What is the minimum fuel temperature?

A

Minimum fuel temperature -37°C unless actual fuel freeze point is known.

35
Q

What must lateral fuel imbalance between main tanks 1 and 2 be scheduled to be?

A

Zero.

Allowable lateral imbalance between Main Tanks 1 and 2 must be scheduled to be zero.

36
Q

Fuel imbalance must not exceed how many pounds?

A

Transient fuel imbalance must not exceed 1000 lbs for taxi, takeoff, flight or landing.

37
Q

If the Center Tank contains more that 1000 lbs what must the Main Wing Tanks be scheduled to be?

A

Full

Main Wing Tanks must be scheduled to be full if the Center Tank contains more than 1000 lbs.

38
Q

When must ground operation of the Center Tank FUEL PUMP switches must be in the OFF position? What is the exception to this rule?

A

For ground operation, Center Tank FUEL PUMP switches must not be positioned to ON unless the Center Tank fuel quantity exceeds 1000 lbs, except when defueling or transferring fuel.

39
Q

What condition must be met to have the Center Tank Fuel Pumps on?

A

Center Tank Fuel Pumps must not be on unless personnel are available in the Flight Deck to monitor LOW PRESSURE lights.

40
Q

When must the Center Tank FUEL PUMP switches be OFF?

A

when the LOW PRESSURE light illuminates.
If the Center Tank is empty.
If personnel are not available in the Flight Deck.
For Ground operations when Center tank quantity is less than 1000 lbs

For ground and flight operations, the corresponding Center Tank Fuel Pump switch must be positioned OFF when the LOW PRESSURE light illuminates. If the Center Tank is empty, position both Center Tank FUEL PUMP switches to OFF.

41
Q

What does ground operation of electric hydraulic pump require?

A

Ground operation of electric hydraulic pump requires minimum 1675 lbs in respective fuel tank.

42
Q

When must the (Max) Engine anti-ice be turned off?

A

(MAX) Engine anti-ice (EAI) must be turned off when not in actual or anticipated icing conditions.
