What is the function of a vortex generator? - It is designed to delay of 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 of an aircraft? - The ailerons, elevators, and rudder. 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, pushpull 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 collec
