Pilot’s Operating Manual
ELEVATOR CONTROL SYSTEM (Figure 5)
The elevator control surfaces are hinged from the rear of the horizontal stabilizer and each is installed
with a mass balance weight to prevent flutter and a horn balance to reduce the aerodynamic loads felt
by the pilot. A spring and a g-weight are connected to the left control circuit to provide acceptable stick
force characteristics.
A stick shaker motor is attached to each control column and is operated by the stall warning system. A
stick pusher unit is connected to the elevator cable system to provide a positive push forward (pitch
down) at the onset of stall identification. The cable circuit also provides an input for the autopilot servo
unit.
Primary stops controlling the range of elevator movement are located on the middle hinge of each
control surface. Secondary stops are located at the pulley drums under the flight compartment floor.
