HUD
Weapons
A breakaway cross appears in the middle of the PDU to indicate that you must initiate your dive recov-
ery immediately. The breakaway cross is removed when the aircraft begins to climb. The breakaway
cross is displayed only when the HUD determines that, with normal pilot reaction time and a normal 4-
g recovery, the aircraft would bottom out with 1,000 ft or less of ground clearance. The breakaway
cross function is disabled for a dive angle of less than 15 degrees.
CONTINUOUSLY COMPUTED
IMPACT POINT (CCIP)
The CCIP submode (bombs,
rockets, gun) compensates for
dive angle, airspeed, altitude,

and target wind to display a
continuously computed impact
point for the selected weapon.

When the pipper of the CCIP
marker is over the target, press
the weapons release button.
Remember, the CCIP mode is
not magical. The computed
impact point relies on the data
entered and a smooth tracking
run to solve the bombing triangle
equation.

for using CCIP begins with a

normal roll-in. For CCIP BOMBS,
place the aiming line over the
target and allow the CCIP marker
to move up to the target. For CCIP ROCKETS or GUN, place the CCIP marker on the target and hold
it there. Even though the computer compensates for all release parameters, except for pipper place-
ment, releasing near your normal parameters will improve the system's accuracy. You may have to
adjust your release aimpoint because the actual target winds may differ from the forecast winds you
entered into the HUD.
