WorksheetsCPL PoF Asymmetric flight revision
Total questions: 15
Worksheet time: 8mins
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
Asymmetric blade effect does not effect twin engine aricraft:
True
False
Select all the methods of maintaining a constant heading under asymmetric flight:
Using only rudder
Using only bank
Using only pitch
Using rudder and bank
When using only rudder to maintain heading in asymmetric flight the indications would be:
(Select all that apply)
Wings level
Balance ball showing slip towards dead engine
Balance ball centered
Apparent drift towards dead engine
Using rudder and bank to maintain a constant heading provides optimum performance because:
Any extra drag is kept to a minimum
It has a small chance to restart the failed engine
Reduces the use of the elevator reducing drag
Vmca is increased
Using only bank to maintain a constant heading will cause:
Slip to be indicated away from the live engine
Slip to be indicated towards the dead engine
Slip to be indicated towards the live engine
Can increase Vmca
