Revision as of 17:29, 26 June 2007

This list contains definitions for Orbiter or important spaceflight acronyms or abbreviations, especially those appearing in MFDs and various HUD modes.

One entry in this list consists of a term with one or more definitions, like:

Term
Definition
;Term:Definition

Don't use links in the term part of a entry, please do so in the definition part, for keeping a consistent look-and-feel and don't putting to much emphasis on a single definition.

Terms without definitions will get moved to the talk page into the section "Wanted definitions". If you have multiple definitions for a term, the definition part should turn into a numbered list, like:

Term
  1. Definition 1
  2. Definition 2
  3. Definition 3
;Term:
#Definition 1
#Definition 2
#Definition 3

The order of the definitions should be like that:

  1. Orbiter HUD definitions
  2. Orbiter MFD definitions
  3. General Orbiter definitions
  4. Orbiter addon definitions
  5. General spaceflight definitions

If you don't agree to a ordering of definitions, please complain in the talk page about the entry.
