Secondary Flight Controls Trim Systems Trim systems are used to relieve the pilot of the need to maintain constant pressure on the flight controls, and usually consist of flight deck controls and small hinged devices attached to the trailing edge of one or more of the primary flight control surfaces.

Secondary Flight Controls Ground Adjustable Tabs Many small aircraft have a nonmovable metal trim tab on the rudder. This tab is bent in one direction or the other while on the ground to apply a trim force to the rudder. The correct displacement is determined by trial and error.

Autopilot Autopilot is an automatic flight control system that keeps an aircraft in level flight or on a set course.
Autopilot It can be directed by the pilot, or it may be coupled to a radio navigation signal. Autopilot reduces the physical and mental demands on a pilot and increases safety.
Autopilot A single-axis autopilot controls the aircraft about the longitudinal axis and a servo actuates the ailerons.
Autopilot A three-axis autopilot controls the aircraft about the longitudinal, lateral, and vertical axes. Different servos actuate ailerons, elevator, and rudder.
Autopilot More advanced systems often include a vertical speed and/or indicated airspeed hold mode. Advanced autopilot systems are coupled to navigational aids through a flight director. The autopilot system also incorporates a disconnect safety feature to disengage the system automatically or manually.
Autopilot Autopilots can be manually overridden. Because autopilot systems differ widely in their operation, refer to the autopilot operating instructions in the Airplane Flight Manual (AFM) or the Pilot’s Operating Handbook (POH).

Warm-Up – 2/23 – 10 minutes Utilizing your notes and past knowledge answer the following questions: The autopilot system also incorporates a disconnect safety feature to disengage the system automatically or manually. Why is this?
Autopilot More advanced systems often include a vertical speed and/or indicated airspeed hold mode. Advanced autopilot systems are coupled to navigational aids through a flight director. The autopilot system also incorporates a disconnect safety feature to disengage the system automatically or manually.
Chapter Summary Because flight control systems and aerodynamic characteristics vary greatly between aircraft, it is essential that a pilot become familiar with the primary and secondary flight control systems of the aircraft being flown. The primary source of information is the AFM or the POH.
