Q

Go through the run-up checklist

A

Notes: only MOMENTARY feather as to not cause damage to governor
“Props: Exercise” (100-200RPM) means momentary feather 3 times, checking RPM, MP and oil pressure
“Props: Feather check” means you’re listening for a whoosh of air
“Check load sharing” means turn alt switch off/on one by one

Q

What happens to the oil pressure in the prop if you increase the throttle?

A

When you increase the throttle, the props want to spin faster and will for a moment. Then the governor kicks in, removing oil.

Q

What if you try the gear pump 3 times and after 30sec each, it still fails?

A

If the pump is unable to maintain the high pressure, hydraulic pressure will travel from the hi pressure to low pressure chambers and the gear will fall.

Q

Will the prop feather if an engine shuts down due to running out of fuel?

A

NO! Oil pressure is built up and it’s still there (pilot valve stops it from leaving). If you lose an engine due to loss of oil pressure, that is when the prop will feather.

Q

3 components that describe the prop

A 
Full feathering
constant speed (same rpm any attitude)
controllable pitch (can change blade angle)
21
Q

Does the prop use same oil as engine?

A

Yes

22
Q

Where are the fuel sumps?

A

1 on main tank
1 on strainer
2 on crossfeed

23
Q

Combustion heater burns fuel from which tank?

A

R only

24
Q

One of your fuel pumps is broken. What do you do?

A

Aux pump on. Fuel selector on CROSSFEED. Now both engines can take from one tank.

25
Q

Above 100kts, which gear might not lock?

A

Main. Nose wheel will be ok.

26
Q

Define asymmetrical thrust

A

Thrust produced unevenly or off center from prop axis of rotation. Tendency to roll/yaw toward dead engine.

27
Q

Why is 70-80% of climb performance lost when you lose an engine?

A

You have 50% power available, but a lot more drag.

28
Q

Is accelerate stop & accelerate go distance for one engine or 2?

A

It’s for 2.

29
Q

Does duchess have accelerate go distance?

How does this affect how we deal with emergencies?

A

Yes, at ANY weight and density alt. See 5-29 of POH

Know before you takeoff whether you can climb if you lose an engine. Also this is for a new plane w test pilots.

30
Q

What reg #s say duchess not required to climb on one engine?

A

23.2120 and 2125

31
Q

Short field takeoffs

A

Vr 67, pitch for 80 until clear obstacle (200’)

Positive rate = gear up even if runway remains

32
Q

Decision altitude

A

3000’
below that, do the whole drill
above that, do the drill but troubleshoot before feathering (fuel selectors, etc). then checklist, then feather and secure engine
SAY R OR L engine!!!

33
Q

The drill

A

directional control
blue line
mixture, props, throttles, flaps, gear up, FUEL PUMPS ON, identify, verify
(troubleshoot here if needed)
feather, mixture. checklist (secure engine)

34
Q

P Factor

yaw or roll?

A

Yaw
difference in the total component of thrust
bigger arm = worse effect

35
Q

Accelerated slipstream

A

Roll
Difference in total component of lift. Engine sucks air through and over the wing (bernoulli principle)
Arm differential

36
Q

Spiraling slipstream

A

yaw
P factor means air coming through prop on R side is faster (lower pressure). Air travels toward it, so spiraling slipstream goes sideways
Aerodynamic control forces: more effective w more airflow

37
Q

Torque

A

L engine out: asymmetrical thrust makes things worse because it makes lift on operative engine side and it goes same direction as torque effect.

38
Q

COMBATS

A

Critical engine failed and windmilling (max drag)
Operating engine at max t/o power
Max takeoff weight
Bank up to 5°
Aft CG (most unfavorable)
Takeoff configuration (least stability)*
Standard day, 29.92” Hg, 15°C, sea level (max engine power)

*Rudder trim neutral raises Vmc because it’s not helping counteract P-factor. So it limits the available rudder.

39
Q

Can you go props full fwd over 100kts?

A

Yes, in an emergency they can go fwd at any speed. But under 100kts limits stress to the governor.

40
Q

Differential ailerons - do they travel farther up or down?

What are Frise ailerons?

A

Travel farther “up”

Frise - up aileron uncovers a ridge on the bottom that causes drag

41
Q

What time of trim is the rudder?
Elevator?
Ailerons?

A

Rudder - servo
Elevator - antiservo
Aileron - not trim, it’s a differential in tensions

42
Q

What runs the vacuum pumps?

A

Engine-driven (except turn coordinator gyro which is electrical)
However the G5 is not vacuum-driven

43
Q

Can a single generator/alternator charge both batteries?

A

Yes - there’s only 1 battery. Even with the 12V one.

44
Q

What are the voltages for 01R and 83M?

A

01R - alternator 55A 28V, battery 55A 24V

83M - alternator 55A 28V, battery 35A 12V

45
Q

What if you’re a little short on the short field landing?

A

GO AROUND

46
Q

What do you do on base?

A

UNDERSHOOT YOUR TURN

47
Q

You’re on an instrument approach and lose an engine. What do you do?

A

Aviate, navigate, communicate

Directional control and blue line, start to intercept as you do the drill, ask tower to “say again”

48
Q

Remember to ___ on your short-field landing

A

say “max braking”

and go around if you’re gonna land short

49
Q

when it’s time to do maneuvers, don’t forget to…

A

altitude
Best place to land
clearing turn
Declare
