A HUD is a Heads-Up Display: a transparent display that presents data without requiring users to look away from their usual viewpoints. The origin of the name stems from a pilot being able to view information with the head positioned "up" and looking forward, instead of angled down looking at lower instruments. A HUD also has the advantage that the pilot's eyes do not need to refocus to view the outside after looking at the optically nearer instruments First developed in the 1940s for military aircraft (from Wikipedia).

As the newer versions of Oolite have allowed more flexibility with modifying HUD elements since the early days of Oolite v.1.20 in 2004! From the halcyon days of Aegidian's Mega-Walnut dashboard (for the Fer-de-Lance), the HUD designers have risen to the challenge. There was a quantum leap under Cim's tenure as lead designer, when it was made easier to code new HUDs and the range of possibilities was greatly increased. This extended to MFDs. This happened with the release of Oolite v.1.79 in 2013/4.

The most striking versions here include the Coluber, Dangerous & Vimana HUDs.

Ships with custom HUDs: Note also that some ships come with their own HUD versions! Eg.: Coluber Racers - Blue, Red, Yellowbelly & Black; also Isis Interstellar ships, all of Simon B's ships in Neolite-Wolfies and some of his Waka series, some of Wolfwood's ships such as his Asp Explorer (Oolite), etc.

HUDs not shown here: Note also that some HUDs are not shown here: Killer Wolf's Dynamic HUD, Cyan HUD, Clear HUD, etc. See the OXP List and its links for more.

Experimenting with new HUDs The easiest way into all this is probably using HUDSelector which comes with 3 more HUDs to try out (extra-large, large & small). It will then help manage most others you download.

Four points:
1) The game specifies 2 types of HUD: small (for the Adder, the Cobra Mk.1, etc) and regular. Most of these do not have a small variant, so you will find that your small ship defaults to the Vanilla game HUD! 2) The number of MFDs varies with the HUD (from 0 to 15)!
3) HUD designers often include icons for their favourite oxp equipments. See Coluber (& Deeper Space), CB (& CRR), Vimana & Z-GrOovY MiLHUD below for examples.
4) A number of HUDS have special features
