|
Define service ceiling
|
No greater than 100 fpm
|
|
Define single engine service ceiling
|
altitude at which no greater than 50 fpm can be maintained
|
|
What 3 factors determine critical engine?
|
P-factor
Accelerated Slipstream Torque |
|
Define P-factor
|
descending blade creates more thrust than ascending = asymmetrical thrust on each side of prop
|
|
Define accelerated slipstream
|
the spinning props accelerate the air going over the airfoil, producing more lift there
|
|
What is torque in relation to ME aerodynamics?
|
Torque is when the prop creates a force opposite rotation due to Newtons third law, adding to or subtracting from resulting yaw in a conventional twin
|
|
What is Vmc?
|
minimum control speed with crit engine inoperative. minimum speed to maintain directional control
|
|
What are the four warning signs of Vmc?
|
Loss of directional control
Stall warning horn Buffeting rapid decay of control effectiveness |
|
What effect does power have on Vmc?
|
more power, more yawm Vmc up
|
|
Temp increase/ pressure decrease on Vmc?
|
Vmc down, less dense, less power, less yaw
|
|
What effect does a windmilling prop have on Vmc?
|
Vmc up, more drag, more yaw
|
|
What effect does an aft CG have on Vmc?
|
Vmc up, less distance between CG and rudder = less effectiveness
|
|
Heavier weight on Vmc?
|
Vmc down, more weight = more lift
|
|
What effect do flaps have on Vmc?
|
Vmc down, because more induced drag on good engine side prevents yaw
