Calculating Aspect Angle

Target aspect and aspect angle are two ways to view similar relationships. Aspect angle is how

the bogey sees the fighter measured to the tail of the bogey.

AA = 180 - (180 - HCA - AO)

= 180 - TA

While Navy and Marine Corps weapons systems use target aspect, the Air Force uses aspect

angle. At VT-86, aircrew will use target aspect to control intercepts.

Intercept Triangulation

Once aircrew establish the bogey and fighter positions on their respective flight paths, a

triangle is formed by the flight paths and the bearing line between aircraft.
