Quiz: Could You Handle These 6 Multi-Engine Failures?

Boldmethod

Could you handle an engine failure in a twin?


  1. 1) You're flying with an engine inoperative, and you need achieve zero-sideslip flight. To do that, you bank slightly toward the operating engine and ________.

    You need to deflect the ball roughly 1/2 out of center toward the operative engine. And in addition to that, you need to bank roughly 3-5 degrees into the operative engine as well.

  2. 2) At 5,000' MSL, what is the minimum required single-engine climb rate of a multi-engine aircraft that has a max weight of 6,000 pounds or less and has a Vso 61 knots or less?

    There is no requirement for a single-engine positive rate of climb at 5,000 feet or any other altitude. For light-twins type certificated February 4, 1991, or thereafter, the single engine climb gradient (positive or negative) is simply determined.

  3. 3) You're flying at altitude with an engine inoperative. You slow to Vmc. Once you hit Vmc, can you maintain directional control?

    Vmc is minimum controllable airspeed, which means you can still maintain directional control.

    Vmc is minimum controllable airspeed, which means you can still maintain directional control.

  4. 4) Which engine is critical in a multi-engine airplane with conventionally rotating propellers?

    The left engine is critical. That's because if you lose the left engine, your performance is more adversely affected.

    The left engine is critical. That's because if you lose the left engine, your performance is more adversely affected.

  5. 5) How is Vmc marked on most airspeed indicators?

    Most light twins have a red radial line that marks Vmc. 

    Most light twins have a red radial line that marks Vmc. 

  6. 6) What prevents most multi-engine aircraft propellers from feathering in flight when the engine is operating normally?

    Oil pressure from the engine prevents the propellers from feathering in flight.

    Oil pressure from the engine prevents the propellers from feathering in flight.

Not bad, just keep working at it...
