FLIGHT CONTROLS
GENERAL
All aerodynamic controls, with the exception of the flaps and speed brakes, are mechanically actuated
by cables. The ailerons, elevator and rudder have trimmed control surfaces and cockpit trim position
indicators.
Flaps are hydraulically powered and can be operated to 15° at 200 KIAS or below and 35° (full
travel) at 173 KIAS or below. Spoiler-type speed brakes are hydraulically actuated and electrically
controlled and can be extended throughout the flight envelope.
AILERONS
The ailerons provide excellent lateral control throughout the entire operating envelope. Full range of
travel is 19° , ±1° up and 15° , ±1° down. One trim tab, located on the left aileron, is mechanically
controlled by a knob on the center pedestal. An indicator on the pedestal shows the amount of trim
selected in relation to a neutral position.
ELEVATOR
Elevator control is mechanical through four cable assemblies. Full elevator travel is through a range of
18°, ±1° up, to 15°, ±1° down. Elevator trim tabs installed on each elevator can be positioned electrically
or mechanically through cockpit trim tab controls. Full travel of the tabs is 4.5°, +0 or -0.5 up and 11°,
+0.5 or -0° down. An elevator trim wheel on the pedestal provides manual trim control. An indicator on
the pedestal shows the amount of trim selected in relation to the takeoff position and full travel.
A trim switch, located on the left side of the pilot's control wheel, controls an electric trim motor which in
turn positions the elevator tabs. The copilot’s trim switch is located on the right side of the copilot's control
wheel. The pilot's trim switch has priority and will interrupt and override the copilot's control. If the electric
trim malfunctions, it can be overridden by the manual trim system, or momentarily disabled by pressing the
AP/TRIM DISC switch on the pilot's or copilot's yoke.
Pulling the PITCH TRIM circuit breaker on the left circuit breaker panel will remove power from the electric
trim motor. The elevator trim is mechanically interconnected with the flap system and will automatically
provide trim compensation during UP or DOWN travel of the flaps between 15° and 25° of flap position.
The flap trim compensation will also trim the airplane any time the electric trim is actuated while the flaps
are in motion regardless of flap position. The flap-trim rate is faster than the electric trim rate and the two
inputs are additive. Consequently, if the pilot is actuating the electric trim in the opposite direction to the
flap compensation while the flaps are in motion, the net result will be a slow trim rate in the opposite
direction to what the pilot has selected. The flap-trim can also be overridden by the manual trim or
momentarily disabled by pressing the AP/TRIM DISC switch.
