Examples

Electronic fly-by-wire systems can respond flexibly to changing aerodynamic conditions, by tailoring flight control surface movements so that aircraft response to control inputs is appropriate to flight conditions. Source: Internet

If the missile starts to roll, the gyroscopic force of the disks drives the control surface into the airflow, cancelling the motion. Source: Internet

The top of the vertical tail had a more square shape than the rounder tail used on the prototypes, and a smaller rudder was used to resolve problems with control surface clearance discovered during test flights. Source: Internet

Cylindrical cams can provide motions that involve more than a single rotation of the cylinder and generally provide positive positioning, removing the need for a spring or other provision to keep the follower in contact with the control surface. Source: Internet

The most common type has the follower ride in a slot so that the captive follower produces radial motion with positive positioning without the need for a spring or other mechanism to keep the follower in contact with the control surface. Source: Internet

The movements of flight controls are converted to electronic signals transmitted by wires (hence the fly-by-wire term), and flight control computers determine how to move the actuators at each control surface to provide the ordered response. Source: Internet
