31
Q

Tell me about the full feathering propeller

A

feathering the prop (turning to high pitch) with the blades almost parallel to the airstream will eliminate asymmetric drag forces caused by windmilling when the inop engine is shut down

32
Q

How is pitch controlled

A
  1. oil pressure - low pitch high RPM (unfeathered)
  2. Nitrogen Pressure and Spring - High Pitch - low RPM (towards feather)
    - helps to prevent overspeeding
33
Q

Tell me about feathering operation

A

full aft movement of the prop control
min RPM to feather is 950RPM
Oil is accumulated under pressure

34
Q

Tell me about unfeather Operation

A

prop control forward
release of oil under pressure in the accumulator
bladed move out of feather

35
Q

what prevents the engine from feathering

A

Anti Feathering pins and the engine RPMS being lower than 950RPM which operates off of centrifugal force

36
Q

what is centrifugal force

A

force that acts outwardly away from the center of rotation on an object moving in a curved path

37
Q

what happens when you unfeather a system

A

increased capacity governors
nitrogen charged accumulators
oil under pressures is released back to governor

its anywhere from 10-17seconds to feather
its 8-12seconds to unfeather

38
Q

how many governors do we have in the PA-44-180

A

2
1 governor per engine

39
Q

what does a governor do

A

supplies and boosts oil to maintain constant RPM settings

40
Q

what are different types of fuel systems

A

gravity fed and pump assisted

41
Q

Tell me about fuel pumps

A

There are the main pumps, auxiliary pumps and emergency back-up

these pumps are electric and hydraulically driven

42
Q

what are the two induction systems

A

carburetion and fuel injection

43
Q

give me pros and cons to a carbureted fuel system

A

pros: lighter, easy to work on, cheap
cons: not as precise, abrupt maneuvers and can have carb icing

44
Q

give me pros and cons to a fuel injected fuel system

A

pros: efficient, precise, no carb icing
cons: heavier, harder to work on, vapor lock

45
Q

what is vapor lock

A

liquid fuel changes state to a gas while still in the fuel delivery system.
fuel is overheated and turns into a vapor in the fuel injector or lines

46
Q

Tell me about the PA-44-180 fuel system

A

110 gallons
108 usable
1 gal unusable per tank

47
Q

how many fuel pumps does the PA-44-180 have

A

2 engine fuel pumps
2 aux. electric driven fuel pumps
- these have to be on for t/o, landing and intentional maneuvering
1 heater fuel pump

48
Q

tell me about the engine

A

4 stroke system with 1 event
1. intake - mixing of fuel and air
2. compression
5. ignition
3. power - combustion
4. exhaust - as gas leaves

49
Q

what way does the left engine rotate? right engine?

A

Left engine : clockwise
Right engine: counterclockwise

50
Q

what does direct drive mean

A

the prop is directly connected to the crankshaft and both turn at the same rate. there is no reduction gearing

51
Q

what is the fuel servo

A

fuel to air ration
air that’s either filtered or unfiltered
often referred to as the butterfly valve

52
Q

tell me about the fuel injected system

A

tank -
fuel pump - through the system to
fuel control unit - regulates amount of fuel needed based on mixture
fuel manifold - fuel is held before being distributed
discharge nozzles - spider lines

53
Q

tell me about the oil system

A

it cleans, cools, and lubricates

54
Q

tell me the flow of oil

A

sump- pump-screen-cooler-filter-engine-prop-sump

55
Q

constant speed propellers increase power in flight

A

blade angle increases
torque required to spin the prop increase
a/c speed torque on engine will increase

56
Q

tell me about the alternators on the PA-44-180

A

there are two rocker switches
primary electrical power source
2 belt driven, 28 volt, 70 amp

57
Q

what protects the alt from failure

A

voltage regulator - effective load sharing while delivering 28v to the system
overvoltage relay: prevents damage, takes off line if exceeds 32v
(ALTR fails cas message)

58
Q

tell me about the battery

A

13.6 amp. hr
24 volt
emergency battery

59
Q

how many electrical buses do we have

A

6

60

A

100 knots

66
Q

how long is the gear cycle

A

6-7 seconds

67
Q

how does retracting the landing gear work

A
