What is the function of aileron an airplane?
Rotates the airplane along its longitudinal axis.
What is a stabilator?
A single piece of horizontal tail surface that acts as both the horizontal stabilizer and the elevators. It pivots about its front spar.
What is the function of the elevators on an airplane?
Rotates the airplane about its lateral axis.
What is the function of the rudder on an airplane?
Rotate the airplane about its vertical axis.
What is the purpose of an aileron balance cable?
It ties the aileron together in such a way that when one aileron deflects downwards the other is pulled upward.
What is an aerodynamically balanced control surface?
A surface with a part of its area ahead of the hinge line. When the surface is deflected the portion ahead of the hinge aids the movement.
What is meant by differential aileron travel?
When the upward movement deflects a greater distance than the downward movement. Upward movement produces parasite drag to counteract the induced drag produced by the downward movement.
What is a frise aileron?
An aileron with its hinge line setback from the leading edge so that when it's deflected upward, part of the leading edge projects below the wing and produces parasite drag to help overcome adverse yaw.
What is a ruddervator?
Movable control surfaces on a V-tail airplane that are controlled by both the rudder pedals and the control yoke.
Moving the yoke in or out, the ruddervator move together and act as elevators, and when the pedal is depressed the ruddervator move differentially and act as rudders.
How much is a fairlead allowed to deflect on a control cable?
No more than 3°
