Multi Transition Flashcards
Vr
Rotation Speed - the speed at which back stick pressure is applied to rotate the airplane to a takeoff attitude
Vlof
Lift-off speed - the speed at which the airplane leaves the surface
Vx
Best angle of climb speed
Vxse
Best angle of climb speed with one engine inoperative (OEI)
Vy
Best rate of climb speed
Vyse
Best rate of climb speed with one engine inoperative (OEI). Marked with a blue line on most airspeed indicators. Above single engine absolute ceiling, Vyse yields the minimum rate of sink.
Vsse
The minimum speed to intentionally render the critical engine inoperative, published in the AFM/POH
Vref
Reference landing speed - 1.3 times the stall speed in the landing configuration
Vmc
Minimum (directional) control speed with the critical engine inoperative. Marked with a red line on airspeed indicators.
What is the critical engine?
The engine that, if it failed, would have the most adverse effect on control. Typically a result of p-factor pushing the center of thrust outboard.
What is the accelerate-go distance?
The distance required to reach either Vr or Llof and, assuming and engine failure at that instant, to continue the T/O run and reach a height of 50 ft.
On a multi-engine constant-speed propeller, aerodynamic forces tend to drive the blade angle to (high/low pitch)
low pitch, high RPM
On a multi-engine constant-speed propeller, counterweights attached to the shank tend to force the blade angle to (high/low pitch)
high pitch, low RPM
On a multi-engine constant-speed propeller, oil pressure from the governor is used to counteract the counterweights and force the blades to…
low pitch, high RPM (a loss of oil pressure results in high pitch, or feathered)
How do you identify the dead engine?
“dead foot – dead engine” Because rudder pressure is applied toward the working engine to maintain directional control
