Effect of turbulence
Increase Vmca
- less rudder available to correct yaw
Effect of bank
Decrease Vmca
-5% AoB - more rudder available
Lower airspeed
Increase Vmca
Less effective on control surfaces - greater control input required to maintain directional control
Higher airspeed
Decrease Vmca
Greater effectiveness of controls- less control input required
Increase power
Increase Vmca
More thrust means greater IAS to maintain control
Following an engine failure, one engine flies in front of the other, which engine is it and why?
The dead engine will fly ahead of the live engine - aircraft is flown with slight sideslip. Thrust side force and fuselage side force will be balanced by rudder side force.
