Assembly and Rigging Flashcards
What flight control surfaces are in the primary group?
Ailerons, Elevators and Rudder
What are the three axes of an aircraft?
Lateral, Longitudinal and Vertical.
What flight controls are included in the secondary group?
Flaps, slats, slots, speed brakes,spoilers.
What is the purpose of vortex generators?
They provide bondary layer air control.
What is a servo trim tab?
It is an auxiliary control that creates aerodynamic forces to assist in moving a
control surface. (only the servo trim tab moves in response to movement by the pilot
of the primary flight controls)
What is a balance trim tab?
It is an auxiliary control that create 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 aid the movement of a primary control during high speed flights.
Name four high-lift devices.
Leading edge and trailing Flaps,Slots,Slats.
What is the purpose of a rotorcraft cyclic pitch control?
Change the pitch of the main rotor blades during its cycle of rotation.
What is the purpose of the rotorcraft colletive pitch control?
It varies the lift of the main rotor blades simultaneosly.
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 trough fairleads.
What is a cable fairlead?
A cable guide that prevent the cable from rubbing on the aircraft structure
