The [http://en.wikipedia.org/wiki/Head-up_display '''Head-up display'''] (HUD) is an important instrument in modern, mostly military, cockpits. FlightGear provides a XML-based system to relatively easily create HUDs for aircraft such as the [[F-14]] and [[F-16]].
The {{Wikipedia|Head-up display|'''Head-up display'''}} (HUD) is an important instrument in modern, mostly military, cockpits. FlightGear provides a XML-based system to relatively easily create HUDs for aircraft such as the [[F-14B]] and [[F-16]].


However, this article's focus is on FlightGear's default head-up displays. Those are available for any craft which does not include its own set. Have a look at [[#Further Information|Further Information]] if you're planning to create a HUD.

Activate the HUD with the '''<tt>[h]</tt>'''-key. Pressing it repeatedly moves through the configured colours and turns it off again. To change the brightness, press '''<tt>[shift]</tt>+<tt>[h]</tt>'''. Press '''<tt>[shift]</tt>+<tt>[i]</tt>''' to go through the available HUD's. Press '''<tt>[i]</tt>''' to switch back to the first one at any time. Have in mind that some aircraft do assign one or more of those keys differently and therefore one or more function/s is/are missing on them.
