Revision as of 14:23, 21 December 2024

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

Definition 1
Definition 2
Definition 3

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

The order of the definitions should be like that:

Orbiter HUD definitions
Orbiter MFD definitions
General Orbiter definitions
Orbiter Add-on definitions
General spaceflight definitions

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

A

ACC: Acceleration, used in Surface MFD to indicate increasing or decereasing horizontal speed of the ship in m/s²
ACT: Activate, command button in RCS attitude MFD in docking mode to activate the programmed orientation to the target dock
AgP: Argument of periapsis:The angle in the orbit from the point of the ascending node to the point of periapsis, displayed in Orbit MFD
ALT or Alt: altitude, distance from the body surface

Used in Orbit MFD when Alt mode is selected to indicate distance from the surface of the body
Used in Surface MFD to indicate altitude in km from the body surface

AN: ascending node:a vector in an orbit where the body passes from south to north of the plane of reference (i.e. ecliptic or equatorial). Shown in Align MFD and Orbit MFD as a dotted vector line connecting to a solid square on the orbit.
AOA: Angle of attack, the difference between the ship's direction of travel and the pitch of its nose

Used in Surface MFD to indicate the angle of attack

AORP: Autonomous Orbiter Rapid Prototype, a system to allow a shuttle orbiter to land without crew.
AP: Used in Surface MFD, a red rectangle with white "AP" in the altitude tape to indicate the altitude of the ship's apoapsis
ApA: apoapsis apoapsis altitude, the lowest altitude of an orbit, displayed in Orbit MFD.
ApD: apoapsis apoapsis distance
ApR: apoapsis apoapsis radius, displayed in Orbit MFD
ApT: time to apoapsis in seconds, displayed in Orbit MFD
AR

Automatic Reference, used in Align MFD, Orbit MFD as a command button for Align to select a reference body automatically based on highest gravity
Altitude Range, used to manually set the range in the altitude graph in Ascent profile MFD
acceptance review

atmo: atmosphere
ATV

Autonomous Transfer Vehicle, an unmanned cargo spacecraft, see ATV.
Automated Transfer Vehicle[1]

AU: astronomical unit
AX: Axis, command button in RCS attitude MFD to change the selected axis beetween pitch/yaw/roll
