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 secundary 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 hight speed flights.
Name four hight-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.
What are cable tension regulators?
They are mechanical devices that automatically maintain cable tension to compensate for expansion and contraction of the aircraft structure.
What tools are primarily used to check control surface travel?
Protators, rigging fixures, contour templates and rules.
What items must be know before using a typical cable rigging chart?
The cable size and ambient temperature.
What should control surfaces be locked when an aircraft is parked?
To prevent damage from the Wind.
Describe some of the tools used to check control surface travel:
A universal propeller protactor or special control surface protactor.
