What are the three axis of aircraft?
Lateral, longitudinal and vertical
What flight controls are included in the secondary group?
Flaps, slats, slots, speed breaks, spoilers
What is the purpose of Vortex generators?
They provide boundary layer air control
What is a servo trim tab?
It is an auxiliary control that creates aerodynamic forces to assisted moving a control surface.
What is a balance trim tab?
It is an auxiliary control that creates aerodynamic forces to assist in moving a control surface
What are three mechanical methods used to actuate flight control systems?
Cables, push pull rods and torque tubes
What is a spring tab?
It is an auxiliary control that aids the movement of a primary control during high speed flights
Name four High lift devices
Leading edge, trailing edge, flaps, slots, slats
What is the purpose of a rotorcraft cyclic pitch control?
Change the pitch the main rotor blades during its cycle of rotation
What is the purpose of the rotorcraft collective pitch control?
It varies the lift of the main rotor blades simultaneously
What unit compensates for helicopter main rotor torque?
The tail rotor
What controls a helicopter tail rotor?
Foot pedals
Where does breakage of control cables occur most frequently?
Where cables pass over pulleys and through fairleads
What is a cable fairlead?
A cable guide that prevents the cable from rubbing on the aircraft structure
