ControlSurface

Controllable surface are those movable components which make aircraft flyable in the are:

• Control surface - ailerons, elevators, rudder
• Leading edge flaps and/or slats and their supports
• Trailing edge flaps and their supports

The following flight load conditions should be reviewed:

a) structural loads:

• due to air loads in flight
• consider stiffness and flutter
• due to ground gust

b) hinge loads

• due to air loads in flight
• due to ground gust
• hinge loads (perpendicular to hinge line) on control surface due to wing or empennage box bending

c) miscellaneous loads on control surfaces
