The two "Useful MFDs" are shown in the upper corners of this "Coluber HUD" which actually has 7 MFD 'slots'


A multi-functional display (MFD) provides extra information on your Heads-Up Display (HUD) during flight.

A multifunction display (MFD) is a small-screen (CRT or LCD) surrounded by multiple soft keys (configurable buttons) that can be used to display information to the user in numerous configurable ways. MFDs originated in military aircraft in the late 1960s (from Wikipedia).

List of basic MFDs

There is a wide choice of MFD OXPs available in Oolite.

  • BroadcastComms MFD enables you to communicate with local ships
  • CommsLogMFD keeps a long record of previous (non-Broadcast Comms) messages which you can scroll through.
  • Combat MFD tells you about both your combat status and your target's!
  • Damage Report MFD lists what is damaged (more information available when docked).
  • Market Inquirer tells you the in-system published prices for the Oolite commodities (ie at major orbital stations and cruise ships).
  • Manifest MFD lists the contents of your cargo hold
  • Manifest Scanner lists the contents of other cargo holds!
  • Navigation MFD shows details of your hyperdrive status, the systems you are in and wish to jump to, etc.
  • Primeable Equipment MFD allows you to use a MFD to select your Primeable Equipment. Very useful if you have a large selection!
  • Range Finder MFD shows you .oxp scan results for escape capsules, black boxes, asteroids, ships, communication relays and cargo pods.
  • Ship's Library OXP comes with the Ship's Manual loaded. There are 5 other books you can add.
  • Station Dock Control allows you to see scheduled departures/arrivals at an orbital station.
  • Star System Lane Indicator MFD allows you to see if you are on a Star System Lane.
  • Telescope tells you what is visible in your viewscreens.
  • Technical Reference Library displays information about a targeted ship
  • Trophy Collector displays your last 10 kills
  • Useful MFDs gives 2: a general information and a cargo-list. Free!

OXPs with added MFDs

Other OXPs use an MFD to interact with what they do.

  • Bounty System - the new bounties can be displayed on an MFD
  • EscortDeck - the MFD shows the status of your escort ships - and governs their activities
  • Fighters - the MFD shows the status of your fighters - and governs their activities
  • GalCop Missions - the Range Finder MFD shows the results of energy-intensive searches for distant escape capsules, cargo pods, black boxes etc.
  • Target System Plugins - sells 2 targeting MFDs: a Short Range Snapshot & a Target Memory Interface.
  • Waypoint Here - the location of your waypoints can be displayed on an MFD

OXPs which manage MFDs

Two important OXPs for MFD users:

  • MFD Restore After Load records your MFD settings for a new game. Note that this is duplicated by HUDSelector, below.
  • Auto-prime equipment OXP primes the appropriate equipment when its MFD is selected. So if you wish to communicate with another ship you can prime the BroadcastComms MFD by selecting it (using the : & ; buttons) instead of using the N button.

There are another two OXPs which enable you to juggle your MFDs

  • MFD Fast Configuration a complex .oxp allowing you to define sets of MFDs for display in different conditions (combat, docking etc.).
  • HUDSelector (HUD Selector with Large HUD) allows you to toggle between different HUDs with different MFD settings. It also records your MFD settings for a new game.
Note that MFDs (& HUDs) need to be "HUD Selector-compliant" for everything to work properly. See Add a MFD into HUDSelector

Note that Docked HUDs might interfere with remembering which MFD goes where.

MFDs which manage OXPs


The MFDs are defined by the HUD you are running. The number of MFDs, their size, position & colour. That is why there are now two different Vimana HUDs - one supporting 6 MFDs, the other 12 MFDs - and why the 6MFD Vimana has green MFDs whilst the 12MFD Vimana has blue ones!

  • The Vanilla game HUD only supports two MFDs.
  • Some of the old HUDs from 2006 probably support none (unless the Vanilla game programming overrides the HUD oxp in this regard).
  • Some of the newer HUDs support up to 12 MFDs - often of different sizes.
  • MFDs do block your view. Hence the attractions of MFD Fast Configuration which allows you to automatically banish the inessentials when in Red Alert (see OXPs which manage MFDs above). And of HUDs such as the Vimana HUD which "incorporate" a number of MFDs (Combat, Navigation and Damage Report) into the actual HUD display itself.

Managing your MFDs

Two issues: selecting which MFDs you wish displayed on your Viewscreen/HUD and which of the MFDs you wish to be active at the moment. Some HUDs have only 2 slots for MFDs (ie can only show 2 MFDs at a time), some have 4, 6, 12 etc.


: select next MFD - ie move from MFD slot 3 to MFD slot 4 on your viewscreen
ctrl : select previous MFD - ie move from MFD slot 4 to MFD slot 3 on your viewscreen
; cycle current MFD forwards - ie choose which of your possible MFDs you want in slot 3 on your viewscreen - or if you want to leave that slot blank
ctrl ; cycle current MFD backwards

Selecting which MFDs to display

  • Select the position/slot you wish to fill using the : & ctrl : buttons
  • Cycle the MFDs you have available using the ; & ctrl ; buttons until you have selected the MFD you want. Then move to the next slot as above.

Activating a MFD

eg to select BroadcastComms to communicate with another ship Just press the : & ctrl : buttons until your desired MFD is highlighted!
