What is the function of a vortex generator?
It is designed to delay or prevent separation of the boundary layer.
What are the three axes of an airplane?
Longitudinal, lateral, and vertical.
What are the three primary flight controls on an aircraft?
The ailerons, elevator, and rudder.
Name several secondary flight controls and describe their general purpose?
Secondary flight controls consists of various types to trim tabs such as balance tabs, anti servo and servo tabs, and spring tabs. Their function is to assist the pilot in moving the controls and to trim the aircraft to fly hands off.
Name several types of auxililary flight controls and describe their general purpose.
The auxiliary flight controls consist of the various high lift devices used during low speed flight such as leading and trailing edge flaps, slats, slots, speed brakes, etc.
What is a servo trim tab?
It is an auxiliary control, positioned by the movement of a cockpit control and designed to create aerodynamic forces to assist in moving a control surface.
What is a spring tab?
It is an auxiliary control designed to aid the movement of a primary control at high speeds when control forces become too high.
What is a balance trim tab?
It is an auxiliary control designed to create aerodynamic forces to assist in moving a control surface. The tab is positioned by a control rod connected to the fixed surface on the same side as the horn on the tab.
What are four most common types of high lift devices?
Leading and trailing edge flaps, slats, and slots.
Describe some of the tools used to check control surface travel?
A universal propeller protractor or special control surface protractor.
Name three mechanical methods by which flight control systems may be actuated.
Cables, push pull rods, and torque tubes.
What is a fairlead?
It is a device to prevent a cable from rubbing on the aircraft structure.
What are the most likely places for a control cable to wear or break?
Where cables pass over pulleys or through fairleads.
What information is required before a cable rigging chart can be used?
The ambient temperature and cable size.
What is the function of a cable tension regulator?
It automatically adjusts the cable tension to compensate for expansion and contraction in the aircraft structure.
