2A-27-40: Roll Flight Controls System:
1. General Description:
The ailerons are manually and electrically controlled, mechanically actuated and
hydraulically boosted airfoils located on the outboard trailing edge of the left and
right wings. Aileron travel is eleven (11) degrees up and down. Aileron movement
is visually depicted on the FLIGHT CONTROLS synoptic page.
Aircraft roll is accomplished by movement of the control wheels which transmits
motion through conventional mechanical linkage (cables, cranks and pushrods) to
displace the ailerons. Hydraulic boost is provided by a hydraulic boost actuator to
assist inputs from the control wheels. During normal flight conditions, aileron
actuators are powered simultaneously by Left and Right Hydraulic Systems (L
