A

P-Factor (Yaw)
Accelerated Slipstream (Roll)
Spiraling Slipstream (Yaw)
Torque (Roll)

39
Q

Why the left is critical ? (which one is false)

A

A critical engine is the engine that more adversely affect fligth when inoperative

40
Q

Why Right engine is L-0360

A

Because turning left, counter clockwise, left engine is turning right, clockwise

41
Q

Vr (normal) : 75
Vref (short) :75
Vref (normal) : 80
Vx / Vyse / Vsse : 82
Vy / Vyse : 88
VLO (UP) : 109
VFE : 111
Va : 3800 ( 135) 2700 ( 112)
VLO (DOWN) : 140
Vno : 169
Vne : 202

44
Q

Will brake system work if landing gear system fails ? Yes, they are separated system

A

The governor controls the oil pressure in/out of the reservior so that it can control the blade angle to
compensate for the over/underspeed situtations

45
Q

Unfeathering actuator
how many on each engine
stores what

A

Each engine will have one unfeathering accumulator.
It stores 90 psi nitrogen so during flight the pilot need to just put the blue levers forward and this can cause the
oil that stored under pressure be sent to the hub to pushing the propeller out of the feather position.
Once the engine is running and have its own oil pressure then the pressure will recompress and recharges the
accumulator for another use.

46
Q

More oil in the hub will make the blade ?

A

decrease the pitch of the blades , increase rpm

47
Q

Vmc flight test conditions:

A

SMACFUM G
Standard day
MAX Power
Aft CG
Critical Engine
Flaps/Gear Up
Up to 5 deg bank
Most unfavourable weight (light weight)

Q

Seminole engines:

A

Lycoming (180 BHP , 2700 RPM)
Horizontally opposed
Air Cooled
Naturally Aspirated
Direct Drive

49
Q

Three things to assist in moving the propeller high pitch,
low RPM

A

The spring of the hub
The nitrogen gas (41 psi)
Counterweight

50
Q

Gear unsafe horn

A

Gear up while on ground
Flap more than 10 and gear not down
Below 14 MP and gear not down

51
Q

Landing gear switches

A

Up limit switches: there is one for each wheel, when all three engaged, then the red light unsafe will shut off.
Turn off heater blower.
Downlock switches: one for each wheel, deactivate the reverse polarity pump (has to be all three engaged),
turn on the green light and shut off the red light and gear horn.
Squat switches: one for each main wheel (weight on wheel concept)
Left side: Prevent the gear retract when the plane on the ground.
Right side: Disable the stall warning horn, disable the mx hour counter (hobbs)

52
Q

. Blue line speed:

A

Vyse 88kt (single engine inoperative best rate of climb speed)

53
Q

. Red line speed:

A

Vmca 56kt (single engine inoperative air minimum control speed)

54
Q

What keep landing gear down?

A

Downlock hook, Down Over-centre lock supported by spring and finger hook

55
Q

Cabin door:

A

2 latched, can land with door open (3-37)

56
Q

Vy definition

A

Best rate of climb (88kt, Vx = 82kt)

57
Q

. Engine cooling by?

A

Engine oil, air cooled, fuel cool ??

58
Q

if gear in transit, what indication?

A

Red WARN GEAR UNSAFE light

59
Q

Vacuum System

A

: 4.8 - 5.2 Hg

60
Q

What drives fuel pumps?

A

Engine driven and electrical motor

61
Q

What is bus bar? Location?

A

Bus bar is a piece of metal used for the distribution of the electricity.
It simplifies the wiring. It is located behind the circuit breaker

62
Q

Electrical bus

A

6 electrical buses that distribute power to electrical
equipment

63
Q

Engine Model

A

Right Engine……………L0-360-EIA6D (turning counter-clockwise from the cockpit)
b. Left Engine ……………..0-360-EIA6D

64
Q

Why Right engine is L-O360

A

: because it turns left, anti-clockwise

65
Q

Reason of “Lo bus” light on:

A

: Alternator low current

66
Q

How Oil pressure affect blade angle:

A

: Lever forward = oil decreases from hub = blade angle decreases
= engine RPM increases

67
Q

Accelerating slipstream:

A

more lift on operating engine

68
Q

Spiralling slipstream

A

: left engine fail = roll left, yaw left

69
Q

What is the function of the recessed vent?

A

a vent that allows only air to flow through to prevent any blockage due to ice formation in the fuel vent line

70
Q
A
71
Q

Hub nitrogen pressure
Accumulator

A

41psi
90psi
