Install A Control Surface Flashcards
What is the function of the ailerons on an airplane?
Ailerons rotate the airplane about its longitudinal axis
What is a stabilator?
A single-piece horizontal tail surface that acts as both the horizontal stabilizer and the elevators. A stabilator pivots about its front spar
What is the function of the elevators on an airplane?
Elevators rotate the airplane about its lateral axis
What is the function of the rudder on an airplane?
The rudder rotates the airplane about its vertical axis
What is the purpose of an aileron balance cable?
It ties the ailerons together in such a way that when one aileron deflects downward the other one is pulled upward
What is an aerodynamically balanced control surface?
A surface with part of its area ahead of the hinge line. When the surface is deflected, the portion ahead of the hinge aids in movement
What is meant by differential aileron travel?
Aileron movement in which the upward-moving aileron deflects a greater distance than the one moving downward. The up aileron produces parasite drag to counteract the induced drag produced by the down aileron
What is a Frise aileron?
An aileron with its hinge line set back from the leading edge so that when it is deflected upward, part of the leading edge projects below the wing and produces drag to help overcome adverse yaw
How much is a fair lead allowed to deflect a control cable?
No more than 3 degrees
In what publication could you find correct control surface movement for a particular airplane?
In the type Certificate data sheet for the airplane
