FLIGHT TRAINING INSTRUCTION T-45 WEAPONS/STRIKE - Cnatra

CHAPTER EIGHT T-45 WEAPONS/STRIKE
Figure 8-39 Continuously Computed Impact Point (CCIP)
The T-45C mission computer uses the radar altimeter for it’s height above target computations.
Absence of the radar altimeter (above 5000’ agl for example or if the RALT is turned off), the
mission computer uses barometric altitude minus entered target height to determine the height
above target. A noticeable “jump” in the CCIP release cue is common passing 5000’ agl as the
CCIP sight transitions from using barometric altitude to radar altitude.
To smooth this transition, the entry of Target Height (TGHT) into the system is recommended.
INSTRUCTOR NOTE
The acceptable error tolerance for the T-45C radar altimeter is 10%
of the actual radar altitude. So at 3000’ agl, it can be off by 300’
and still remain within acceptable tolerance.
The procedures for using the CCIP delivery mode are no different than those taught in the
MANUAL delivery mode. We still employ the same techniques of straight path tracking and
curvilinear to straight path tracking, with the exception, CCIP bomb delivery mode produces a
Bomb Fall Line (BFL) to enhance our line-up guidance and a release cue to indicate the proper
time to command weapon release. In the MANUAL mode, you had to determine when to release
based on our current conditions, whereas in CCIP, it tells you when to release. WE ARE STILL
REQUIRED to maneuver the aircraft to the “same piece of sky” for the weapon to fall and
impact the intended target. There is no “magic” involved, but it does take out some of the mental
gymnastics.
