CPL PoF Asymmetric flight revision

The critical engine:

• Is the engine with the longest moment arm between the engine and CoG

• Will be the left engine if the propeller rotates anti-clockwise

• Is the engine with the shortest moment arm between the engine and CoG

• Will be the right engine if the propeller rotates clockwise

The size of the yawing moment in asymmetric flight is effected by:

(Select all that apply)

• How much thrust is coming from the live engine

• Distance between the thrust line and CoG

• How much drag on the failed engine

• Airspeed

• The rate of thrust decay

What are main reasons a failed engine causes a rolling moment to develop:

(Select all that apply)

• Ailerons will automatically get deflected

• Roll is a secondary effect of yaw

• Loss of slipstream over the wing of the failed engine

• There is no rolling motion

In asymmetric flight the aircraft will:

• Roll towards the failed engine but yaw away from the failed engine

• Roll and yaw towards the failed engine

• Roll away from the failed engine but yaw towards the failed engine

• Roll and yaw away the failed engine

The yawing moment is caused by:

• Increased drag on the live engine

• Incorrect rudder usage

• Increased weight on the side of the failed engine

• The thrust line will become offset from the CoG

With a failed engine there will be a decrease in performance:

• True

• False. The live engine can simply increase power to compensate

The immediate action a pilot should take after one engine failing are:

• Control the yaw and identify the failed engine

• Control the roll and identify the failed engine

• Identify the failed engine so it can be feathered or restared

• Control the yaw and roll. Then identify the failed engine

A quick way to remember how to identify the failed engine is:

• Dead leg working engine

• Working leg working engine

• Working leg dead engine

• Lazy leg working engine

Vmca is

• The minimum control speed airborne. Based on full rudder and no more than 10° AoB

• The minimum control speed airborne. Based on half rudder and no more than 10° AoB

• The minimum control speed airborne. Based on half rudder and no more than 5° AoB

• The minimum control speed airborne. Based on full rudder and no more than 5° AoB

Select all the correct statements regarding Vmcg:

• Is the minimum control speed on the ground during the take-off run.

• Assumes the critical engine has failed

• At or above this speed it is possible to maintain directional control with rudder only

• Is applicable to light twin aircraft

• Is not applicable to light twin aircraft
