Initial Descriptive Comm

Once aircrew have received bogey heading and bearing and have determined the proper

fighter heading for collision, aircrew will need to describe fighter and bogey flight path

orientation. The following format should be used:

Example: Bogey heading 320, bogey bearing 160, making fighter heading 180 which

forms a 40 left cut, 140 DTG, left-to-right pass.

Commentary:

"Steady 180, I have a 40 left cut, looking 20 left for 20 right target

aspect, 140 left-to-right, steady 180. "

If in the turn to Collision Heading (CH) a subsequent GCI call puts the bogey over a round,

update the cut to a new CH. After that, stick with your cut unless GCI calls the bogey bearing at

or outside +/- 5 degrees from CB for fighter steady heading (fighter still in the turn). Once

steady on a heading and the bogey is not visible, wait for the GCI calls to get to or through a "0"

or "5", and then make the CCC. If the 1st time you see the bogey on the scope and the bogey is

not on collision within rounds, timeline permitting, make a CCC. If the bogey is on collision

within rounds do not make a CCC until the bogey drifts to a "0" or "5".

Rechecking the Work

It is not uncommon to initially make errors when computing collision course corrections.

Always recheck computations...

starting with a re-evaluation of the cut from the BDHI!

Without a recheck procedure, errors will perpetuate themselves throughout subsequent

collision course corrections.

To prevent and detect errors, aircrew should scan the BDHI and know exactly what cut they

are on. First determine where the bogey reciprocal falls (left or right of fighter nose) and by how

much. This angle is the cut regardless of what previous computations yielded. The cut and the

AO provide the necessary raw data for further correct CCC's regardless of previous errors.

Aircrew must not be concerned with where or how previous mistakes were made, as this will

only put them behind the aircraft and delay recovery.
