VMC Flashcards
What is VMC
Calibrated airspeed at which, when the critical engine is suddenly made INOP, it’s impossible to: Maintain directional control with the engine still INOP And maintain straight flight at the same speed with an angle of bank not to exceed 5 degrees
How does the manufacture determine VMC
C- Critical engine failed and wingmilling
How does the manufacture determine VMC
O- Operating engine at max takeoff power
How does the manufacture determine VMC
M- Most unfavorable weight (lighter)
How does the manufacture determine VMC
B- Bank angle of no more than 5 degrees
How does the manufacture determine VMC
A- Aft CG
How does the manufacture determine VMC
T- Takeoff configuration- Flaps and gear up
How does the manufacture determine VMC
S- Standard temp and pressure
What are the factors for Lowering VMC
add power to critical engine
What are the factors for Lowering VMC
Reduce drag
What are the factors for Lowering VMC
Reduce power on the good engine
