INTERCEPT PROCEDURES TEXTBOOK
With another BB call from GCI, the fighter will adjust heading again, reducing the amount of
lead to gradually decrease range and control drift. When BB = BH, the fighter is situated on the
bogey flight path, somewhere directly astern of the bogey. This simplifies the radar search and
controls drift. All three options are shown in Figure 18.
Rear Quarter Drift Control With Radar Contact
Once in the rear quarter with a low ROC, the fighter should turn to keep the bogey on the
nose. Eventually, the drift will become minimal and the fighter will be on the bogey flight path,
in position to launch a sidewinder. Failure to hold the bogey on the nose will result in the fighter
crossing the bogey's flight path. This overshooting of the bogey's flight path, however small, is
known as "fighter weave" and is undesirable.
