Aircraft general knowledge

If the steering wheel or stick is moved sideways, this moves the ailerons, so that

one goes up and the other goes down and vice versa.

If you step forward on the pedal on the right side, it automatically goes back on
the left side. The pedals are connected by wires to the rudder.

The system for operating the rudders is shown below.

The figure below shows what is actually meant when you say "fly by wire".

Wire also means electrical
wire, and when you activate

the controls, voltage is sent

to an actuator in the

relevant control.

The system enables connection with the autopilot. In the newest aircraft, fiber

optic cables are used.

Before flying, check that the controls are working correctly and can be moved

freely to all extreme positions.

After flying and parking into the wind, control locks are applied to prevent the

controls from moving in windy weather. Chocks are placed around the wheels

and the aircraft is tied down to the ground (follow POH).
