24
Q

Engine power section consists of:

A

A two-stage centrifugal compressors, an annular reverse-flow combustion chamber, and a three-stage axial-flow turbine.

25
Q

General overview of propellers:

A

Oil-operated, constant-speed, full feathering, and reversible.

26
Q

What happens to the propellers when oil pressure is lost?

A

The blades move to feather

27
Q

When should pressure gauges for engine fire extinguishers be checked?

A

Preflight

28
Q

Will one engine provide sufficient bleed air for pneumatics?

A

Yes

29
Q

Regulated bleed air is used for?

A 
De-ice boots
Window defogging
Hydraulic reservoir pressure
Door seal inflation
Vacuum generation
30
Q

Unregulated bleed air is used for?

A

Engine and nacelle inlet anti-icing

31
Q

Bleed-air shutoff valves controlled by toggle switches control what?

A

Air for the pressurization and air-conditioning systems

32
Q

What do we have ELECTRICAL de-icing for?

A 
Propellers
Oil cooler duct inlets
Pitot heads
SAS vanes
Wind-shields
33
Q

We have PNEUMATIC de-icing for what?

A

Wings

Horizontal stabilizer

Compressed bleed air for engine nacelle inlets, ice free static sources.

34
Q

How much PSI is in hydraulic system?

A

2000 psi

35
Q

What is operated by hydraulics?

A

Flaps

Landing Gear

NWS

36
Q

How is landing gear operated?

A

Electrically driven and hydraulically actuated

37
Q

How is NWS operated?

A

Electrically controlled and hydraulically actuated

38
Q

Do brakes have anti-skid?

A

No

39
Q

How are wing flaps operated?

42
Q

What determines who gets the brakes?

A

Whoever uses the brakes first.

43
Q

How does pitch trim work?

A

Electrically moves the horizontal stabilizer.

44
Q

Alternate static port provides reference for what instruments?

A

ONLY the pilot’s instruments. Not the copilot’s.

45
Q

What type of oxygen system do we have?

A

Diluter-demand

46
Q

What happens if the dump valve or you depressurize the plane while using alternate static source?

A

All accuracy of instruments is lost

47
Q

How do you know O2 is flowing?

A

Red dot disappears

48
Q

Why is it important to test O2 before each flight?

A

Mx may not have turned valve back open.

49
Q

What do you set O2 mask for before each flight?

A

100%. It’s on the front of the O2 masks.
