 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 aircrafts such as the [[F-14]] 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]] 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 '''[i]''' 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.
-Some of the head-up display's options can be altered in the menu: <tt>View</tt> --> <tt>Adjust HUD Properties</tt>

 If the autopilot is active the HUD displays its settings. For each active function (heading, altitude and speed) a box will appear below the gyrocompass containing information on its mode and, if existent, the associated value.

+The upper left hand corner shows the most important information on the actual state of the GPS. Namely these are (line by line):
+: the mode the GPS operates in and the active waypoint's identifier.
+: the distance "D" (in nautical miles, nm) and the calculated time to this waypoint "TTW".
+: the bearing "BRG" to the active waypoint and the course deviation "XTR" based on the leg from the previous waypoint.
+: the current speed relative to the ground "GS".

 == Further Information ==
-The setup of the default HUD is defined at <tt>[[$FG_ROOT]]/Huds/default.xml</tt>.
+If you consider to create your own HUD have a look at [[Canvas HUD]] first.
+The setup of the default HUD is defined at <tt>[[$FG_ROOT]]/Huds/[http://mapserver.flightgear.org/git/?p=fgdata;a=blob_plain;f=Huds/default.xml;hb=HEAD default.xml]</tt>.
+The basic settings regarding to any HUD are set in <tt>$FG_ROOT/[http://mapserver.flightgear.org/git/?p=fgdata;a=blob_plain;f=preferences.xml;hb=HEAD preferences.xml]</tt>. Search the file for the <tt><hud></tt>-tag and you will find a list of properties.
-Documentation can be found at [http://mapserver.flightgear.org/git/?p=fgdata;a=blob_plain;f=Docs/README.hud;hb=HEAD <tt>$FG_ROOT/Docs/README.hud</tt>].
+Documentation can be found at <tt>$FG_ROOT/Docs/[http://mapserver.flightgear.org/git/?p=fgdata;a=blob_plain;f=Docs/README.hud;hb=HEAD README.hud]</tt>.
-HUD's may be replaced or added by changing or adding their path(s) to preferences.xml (<hud> tag) or by setting the paths as command line options. To change the order of the existing ones the options would be:  <code>--prop:/sim/hud/path[1]=Huds/minimal.xml</code> <code>--prop:/sim/hud/path[2]=Huds/default.xml</code> <code>--prop:/sim/hud/path[3]=Huds/NTPS.xml</code>
