CONTINUOUSLY COMPUTED
IMPACT POINT (CCIP) MODE
In the CCIP mode, the HUD
displays the same flight
parameters as in MAN mode
(compare Figures 16 and 17).
CCIP compensates for dive angle,
bank angle, airspeed, altitude, and
target wind to display a

continuously computed impact
point for a selected weapon.

into the system. The purpose is to
have accurate BARO altitude

available should the radar
altimeter data input or instrument
fail. During a bomb run in rugged
terrain, the pipper may jump
around as the aircraft passes over
terrain of varying heights. To force
the system to use BARO altitude,
versus radar altitude, the radar
altimeter must be turned off.
In CCIP mode the HUD displays a

vector; sometimes called a

in RKTS or GUN. The bomb fall
line is an azimuth reference between the pipper and the velocity vector that indicates wind and speed
effects on the weapon. When the target and CCIP pipper are coincident, you will command bomb release.
The HUD can be used in A/G either caged or uncaged. The system defaults to uncaged. Should you
occasion to employ the HUD in caged mode, be aware that the bomb fall line is displayed between the
caged (solid) velocity vector and the pipper; not between the true (uncaged ghost) velocity vector and
pipper. Correspondingly, your target may not track down the bomb fall line, as during uncaged mode of
operation.
Proper technique for using CCIP on a bombing run begins with a normal roll-in at the correct point to
establish desired dive angle. Once in the dive maneuver to place the bomb fall line over the target;
proper position for the target along the line will depend upon specific parameters. With experience your
judgment regarding initial target placement will develop. As the dive progresses, the target will move down
the bomb fall line until it is coincident with the pipper. That is the point of weapon release.
CCIP RKTS and GUN pipper flashes when computed slant range to the target exceeds 12,000 feet for
RKTS and 8,000 feet for GUN, indicating that you are outside normal parameters for those weapons. After
