Autopilot joystick management

Overall goal

Realise a simplified aircraft simulator able to perform a runway routine on San Francisco airport.

Joystick role

• Input reading (keyboard or joystick)
• Deactivate autopilot

Input reading

If the joystick is active, commands must be output as load factor (n_z) and roll rate (p).

Operating modes

In normal mode, the auto pilot is activated and the module only forwards inputs from the FCU, changing slightly the message to match specifications. The pilot has the possibility to switch off the autopilot. In manual mode, inputs from the FCU are ignored (except for the (n_x)) and the data read from the joystick are sent.

Switching from autopilot to manual

When the pilot pushed the button, the system waits for the first input from the joystick (i.e. the first move) to send effectively data from the joystick. As long as the joystick isn't used, even if manual mode is enabled, messages are forwarded from the FCU.

Implementation

Reading input

Input from the keyboard or the joystick will be outputted as raw data.

Processing input

The signal retrieved will be processed to obtain a (n_z) and a (p)

Priority management

Decides whether to shut down FCU.
