Q

Your right engine is shut down; how do you get fuel from the right tank to the left engine?

A

The Aero Commander has a single point of fueling, and is a gravity fed system. In the event of engine loss, the boost pump for the operational engine should be turned ON as a precaution.

Q

What happens if you lose a hydraulic pump?

A

The Aero Commander has two engine driven hydraulic pumps for operation of the flaps, landing gear, and brakes; along with an aux electric pump for brake operation during engine starting. In the event one pump fails, it’s unlikely the pilot will have an indication of the failure.

Q

Will you have braking authority with a hydraulic leak or line rupture?

A

In the event of a main hydraulic line rupture, a check valve will stop the loss of hydraulic fluid to the braking system. The only immediately apparent issue will be that the nose gear will fall since it is held up with hydraulic pressure alone and the red uplock light will extinguish. If the flaps are extended and the hydraulic pressure gage falls to the aux levels of 470-600 PSI, the pilot knows they will only have hydraulic pressure for braking.

Q

What happens if the hydraulic leak is from a brake line?

A

If the rupture occurs in a brake line, a complete hydraulic failure has occurred and there will be no hydraulic pressure for braking or the flaps.

Q

What is the emergency gear extension procedure and any associated airspeed limitations?

A

-Slow to between 95-100 mph

-Landing gear lever => DOWN

-Check landing gear position indicators are green

-Flaps up landing recommended airspeed is 85 mph

Q

Define critical engine, does the AC50 have one?

A

The critical engine is the engine that, if lost, will produce the most adverse effects to performance. Due to several factors, if both engines are clockwise rotating engines, the left engine would be critical. The commander is a conventional twin with two clockwise rotating engines; therefore, the left engine is critical.

Q

What is the procedure for restarting a feathered engine?

A

ENGINE RESTART

Prop Lever…………………………………….FULL / HIGH RPM

Generator on operating engine……………OFF

Throttle…………………………………………⅛ OPEN

ALT Air………………………………………….OFF

Cowl Flaps……………………………………..⅔ OPEN

FSOV……………………………………………OPEN

Boost pump……………………………………ON

Magnetos……………………………………….START

Once Engine is Running

Boost Pump……………………………………OFF

Oil Pressure……………………………………CHECK

*If no engine oil pressure is observed within 30

seconds, secure engine and land ASAP

*When engine starts, allow approximately 7

seconds for prop to unfeather

*Warm up engine at 2000 rpm and 13” MP

Alternators…………………………………….ON

Q

When would you abort a takeoff after an engine failure?

A

-Any time below Vmc, when there is enough runway remaining to come to a full stop, or when a single engine climb cannot be made without avoiding obstacles on departure end

17
Q

When should a single engine go around be accomplished?

A

Only when absolutely necessary and when above Vmc

18
Q

What is the legal fuel reserve for a VFR flight? What’s the fuel reserve recommended at BlueSky?

A

Day: 30 minutes Night: 45 Minutes BlueSky: 1 hour

19
Q

Which instruments and systems would be affected if the vacuum pumps failed?

A

Attitude indicator, HSI, de-icing boots,

20
Q

Which instruments would be affected if the static system failed?

A

VSI, ASI, Altimeter

21
Q

Describe how you would use the de-icing and anti-icing equipment on the AC50 to remove or prevent icing.

A

Cycle deicing boots after ice has accumulated. Do not use boots during takeoff and landing.

-Prop deicing is accomplished by an electric heated prop element which melts the ice after or prior to formation.

22
Q

When would you use the alternate air?

A

During the runup to check for blockages, when the normal air intake has become blocked and an alternate air source is required, or to increase the speed at which the engine warms up prior to takeoff or after an inflight engine restart.

23
Q

Describe the initial flow you’d perform in the event of an engine failure:

A

Blue Line => Establish and FLY THE AIRPLANE

Mixtures => Full Rich

Props => Full forward / high RPM

Throttles => Full

Flaps => Up

Gear => Up

Identify => Dead leg, dead engine

Verify => Pull one throttle lever back at a time and listen / watch for mp/rpm change to determine dead engine

Secure => T-M-P on failed engine

Throttle => Idle

Mixture => Lean/Cutoff

Prop => Full Feather

Engine failure checklist => Run

24
Q

Max camera door open speed:

A

200 mph and will not operate with gear in the down position

25
Q

Describe the landing gear system:

A

The landing gear system is an electrically operated and hydraulically actuated system which uses compressed nitrogen to force the gear down in the event of a hydraulic failure.

26
Q

When should the cowl flaps be used?

A

Takeoff: below 60°f CLOSED, above 60°f OPEN ⅔

Climb: Used to maintain engine temps within limits

Cruise: Closed

Balked Landing: As req. To maintain engine temps within limits

If engine fails, on that engine: CLOSED to reduce drag

27
Q

What is the max speed for the autopilot system?

A

Vno

28
Q

May you leave the pilot seat while the autopilot is in operation without another qualified and approved pilot at the controls?

A

-No

29
Q

Is it permissible to override autopilot during normal procedures while pitching or banking?

A

No, disengage the autopilot prior to hand flying during normal conditions

30
Q

What is the maximum allowable increment the flaps can be operated while the autopilot is on?

A

10°

31
Q

How do you disengage the autopilot system?

A

1) Autopilot disengage button on yoke

2) Turning off the autopilot switches located in between left and right seats

3) If autopilot fails to disengage from the prior methods, pull the circuit breaker and land as soon as practicable
