While \Index{joystick}s or \Index{yoke}s are supported as are \Index{rudder} pedals, you
can fly \FlightGear{} using the keyboard alone. For proper control of the plane during
flight via the keyboard (i) the \texttt{\Index{NumLock}} key must be switched on (ii) the
\FlightGear{} window must have focus (if not, click with the mouse onto the graphics
window). Several of the keyboard controls might be helpful even in case you use a
joystick or yoke.

After activating \texttt{NumLock} the following main \Index{keyboard controls} for driving the plane should work:

For changing views you have to de-activate \texttt{NumLock}. Now \texttt{Shift} +
$<$\texttt{Numeric Keypad Key}$>$ changes the view as follows:

Besides, there are several more options for adapting display on screen:

The \Index{autopilot} is controlled via the following keys:

\noindent Ctrl + T is especially interesting as it makes your little Cessna behave
like a cruise missile. Ctrl + U might be handy in case you feel you're just about to
crash. (Shouldn't real planes sport such a key, too?)

In case the \Index{autopilot} is enabled, some of the numeric keypad keys get a special
meaning:
