Name several secondary flight controls and describe their general purpose?
Secondary flight controls consist of various types of 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 auxiliary 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 primary 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 an 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 specal 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 strcture.
What are the most likely places for a control cable to wear or break?
Where the cables pass over pulleys or through fairleads.
What information is required before a cable rigging chart can be used?
The ambient temperature and the 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.
Describe the function of rotorcraft collective pitch control.
The collective control causes each rotor blade to change its pitch angle by the same amount,
thus increasing or decreasing the lift produced by the rotor.
Describe the function of a rotorcraft cyclic pitch control.
The cyclic control tilts the main rotor disc by by changing the pitch angle of each rotor blade
during its cycle of rotation, which causes the helicopter to move in the direction the rotor tilts.
What mechanism is most commonly used to compensate for the torque produced by the main
rotor of a helicopter?
The tail (or anti-torque) rotor.
How is the amount of thrust produced by the tail rotor controlled?
By moving the foot pedals.
