Allied nations may have different meanings for some of the terms/words listed here
(reference ACP 165). They are indicated by an asterisk (*) behind the term/word.
Directive to cease action/attack/event/mission.
Directive to initiate a briefed attack sequence or maneuver.
There are three axis which are mutually perpendicular and have a common point of
intersection. The aircraft longitudinal axis is parallel to the fuselage reference line.
Aircraft rotation around this axis is roll or bank. The aircraft vertical axis is
perpendicular to the longitudinal axis through the center of the aircraft. Rotation around
this axis is yaw. The aircraft lateral axis is perpendicular to both the longitudinal and
vertical axes at the point of intersection. Rotation around this axis is pitch.
Request for bearing and range to described point.
Orbit about a specific point; ground track flown by tanker. Information call indicates a
turning engagement about a specific location.
The angle between the cord line of the wing and the relative wind.
The angular difference between the longitudinal axis of the attacker and the logitudinal
axis of the defender.
Height of aircraft in thousands of feet.
Training term used to denote simulated launch of enemy, all-aspect radar missile.
Training term used to denote simulated launch of enemy, rear hemisphere heat seeking
Cutoff in plane of target motion to decrease range to targetdefender allows attacker to
Select armament (safe/hot), or armament is safe/hot.
Fighter, FAC, mission package, or agency will be performing exactly as stated by the air
Request/comment regarding target aspect information.
The angle between the longitudinal axis of the target (projected rearward) and the
line-of-sight to the fighter, measured from the tail of the target. The attackers heading
is not a consideration. (Whenever the attacker is pointed at the bogey, angle-off and
aspect are the same.)
Indicates air-to-surface attack on a specific ground target.
Rear hemisphere heat-seeking missile.
An orientation direction usually thought of as an imaginary line passing through the
target on some particular headingexample, the range run-in heading.
To request or provide a response for a coded challenge.
Aircrew is operating without benefit of GCI/AWACS control.
Intercepts initiated by aircrew when no target information is being received from
command and control sources.
