Editing heads up display

In [[Orbiter]], the '''heads-up display''' is a standard feature of all [[spacecraft]]. It has three modes, cycled by pressing the H key; it can also be turned off completely with ctrl-H.

==General information==

All HUDs show the current time and camera information in the top right-hand corner. In non-panel modes, they also show engine and [[RCS]] status in the top left-hand corner.

==Surface mode==

The HUD displays a pitch ladder and a cross-in-circle indicator of the current [[velocity]]. (If this overlays the ground, it indicates your projected landing point.) At the top of the HUD is a bearing indicator; this is centred on the vessel's current heading. If a base has been selected in the [[Map MFD]], the direction to that base will be shown as a triangle, either overlaying the bearing strip or pointing off to one side of it. Airspeed and altitude are also shown.

==Docking mode==

This mode displays direction and velocity relative to the selected docking target (normally chosen with a nav radio). A box surrounds the target (or a triangular pointer shows the way); a cross shows your velocity vector relative to the target, and a cross-in-circle shows the opposite vector (which could be considered the target's vector relative to you). You can change the reference navigation radio with ctrl-R (which will also cycle through other docking modes; see the manual).

If you want to match velocity with the target, apply thrust towards the circled cross.

If the reference radio is tuned to an [[IDS]] transmitter, the HUD will show a series of rectangles aligned with the approach course for the docking port, out to a distance of 500 metres. If the ship is orientated to face inward along the row of rectangles, with the double-line side at the top, it will be in approximately the correct attitude for docking with a front port.

==Orbit mode==

This mode displays a pitch ladder relative to the current orbital plane, where the zero line indicates the orbital plane. It also marks the [[prograde]] direction with a cross-in-circle and the [[retrograde]] direction by with a cross. (If neither of these is on screen, a triangular marker points towards [[prograde]]. You can change the reference object with ctrl-R.

==Custom HUD modes==

Since the 2005 edition, Orbiter allows vessels to define custom HUD modes.

 Since the 2005 edition, Orbiter allows vessels to define custom HUD modes.
-Examples for such vessels:
-* [[Shuttle A]] (Cargo pod management)
-* [[Delta-glider]] (Undercarriage)
-* [[Space Shuttle]] 3.8.5 (landing aids)
-* [[Project Sirius]] ([[Ares V]] vessel status and flight director)
-How to paint such a custom HUD mode, see the [[HUD Tutorial (Flight Director)]] from the Project Sirius.
