Q

Fuel system - Components?

A

Fuel selector
Fuel filter
Electric boost pump
Engine driven fuel pump
Servo Regulator
Flow Dividers
Fuel injectors
Throttle

17
Q

Fuel system - Electric boost pump purpose?

A

Provides fuel pressure for priming and as backup to engine driven pump

18
Q

Fuel system - Engine driven pump function and purpose?

A

Diaphragm pump, converts rotary motion from accessory case to linear motion through cam

19
Q

Fuel system - Servo regulator purpose?

A

Measures amount of fuel flowing to injectors. First point of control inside the servo regulator is the fuel control unit which is attached

20
Q

Fuel system - Throttle operation?

A

Throttle opens and closes the butterfly valves which controls how much air is going through the filter and induction manifold.

21
Q

Fuel system - Amounts?

A

77 gal total (38.5 in each)
72 gal usable (36 in each)
Tabs - 50 gal (25 in each)

22
Q

Fuel system - Burn?

A

12.7 gal/hr 65% power @ 2500RPM

23
Q

Induction system - alternate air source?

A

Door that functions automatically when primary source is obstructed, can also be operated manually

24
Q

Engine - layout and information?

A

Horizontally opposed, 4 cylinder, direct drive, fuel injected

200HP @2700RPM

Oil between 6-8 quarts (Skyborne standard)

25
Q

Airframe - MTOW

A

2750lbs

25
Q

Controllable pitch prop - Components and function?

A

Prop governor - Speeder spring and flyweights control flow of oil into hub via valve

Overspeed - Flyweights go out, spring and pilot valve moves up, allowing more oil to entry the hub to make pith more course.

Torque requirement increases, RPM decreases

26
Q

Electrics -Battery and alternator?

A

24V battery, 28V alternator

27
Q

Pitot static system - Locations and use?

A

Pitot tube under left wing, static pressure sensed by button vents on both sides of fuselage.

Used for ASI, altitude, and VSI

Alternate static

28
Q

Pitot static system - Alternate sources

A

Alternate static inside cockpit, left of pilot seat

29
Q

Airspeeds - Vs1/Vs?

A

Vs1 - 55
Vs - 60

30
Q

Airspeeds - Vx, Vy?

A

Vx - Gear Down - 72
Vx - Gear up - 78

Vy - Gear down - 78
Vy - Gear up - 90

31
Q

Airspeeds - Vg?

A

Vg - 79

32
Q

Airspeeds - Vle

A

Vle - Retract - 107
Vle - Extend - 129

33
Q

Airspeeds - Vfe, Va

A

Vfe - 103
Va - 118

34
Q

Airspeeds - Vno, Vne?

A

Vno - 146
Vne - 183
