What is the function of the vortex generator
to delay or prevent separation of the boundary layer
What are the 3 axes of an airplane
longitudinal, lateral and vertical.
What are the three primary flight controls of an aircraft
ailerons , elevator and rudder
Name several secondary flight controls and describe their general purpose
balance tabs, anti-servo tabs, and spring tabs. their function is move the controls and trim the aircraft
Name several types of auxiliary flight controls and describe their general purpose
Leading and trailing edges flaps, slats slots are use as high-lift device at low speed
What is a servo trim tab
it is an auxiliary control designed to create aerodynamic force to assist in moving the control surfaces
What is a spring tab
it is an auxiliary control designed to move primary control at high-speed
What is a balance trim tab
it is an auxiliary control designed to create aerodynamic force to move control surface
What are the four most common types of high lift devices
leading and trailing edge flap ,slat and slots
Describe some of the tools used to check control surface travel
universal propeller protractor, special control surface protractor
Name three mechanical methods by which flight control systems may be actuated
cables, push-pull rod, and torque tube
What is a fairlead
it is a device to prevent cable from rubbing on the aircraft structure
What are the most likely places for a control cable to wear or break
over pulleys or trough fairlead
What information is required before a cable rigging chart can be used
the ambient temperature and size of the cable
What is the function of a cable tension regulator
It automatically adjust the cable tension to compensate for expansion and contraction in the aircraft structure
Describe the function of a rotorcraft collective pitch control
to change it is pitch angle by the same amount thus increasing or decreasing the lift produce by the rotor
Describe the function of a rotorcraft cyclic pitch control
to tilt the main rotor disc by changing the pitch angle of each rotor blade during cycle of rotation
What mechanism is most commonly used to compensate for the torque produced by the main rotor of a helicopter
the tail rotor
19.How is the amount of thrust produced by the tail rotor controlled
by moving the foot pedals
Why should control surfaces be locked when an aircraft is parked
to prevent damage from the wind
