Figure 5-9 BDHI Corrections

The BDHI maneuver is not going to work in this situation; the silo was not within 30 of the

compensated heading. The best course of action is to return to compensated heading, mark

abeam of the checkpoint (noting the distance abeam), and perform a standard correction. This is

depicted in Figure 5-10.

"Jungle Rules" corrections - used only on the target leg with the target in sight!

On the target leg, you may use standard time corrections if less than 12 seconds off. For Jungle

Rules course corrections to the target, turn the aircraft in the direction of the target, and call for

roll out as the target approaches the 12 o'clock position. This maneuver might sound as follows:

"Target in sight, at 2 o'clock, hard right, clear right." As the target approaches twelve o'clock:

"Steady up, target at 12 o'clock." Headings are preferable, not required. In this situation, it is not

necessary to cross the target on preflight heading.

Time Analysis

This is the second step of four which gets the aircraft back on course and on time. During this

step, it is determined how much time (if any) the mission is off from preflight timing. As in the

Turn Analysis, Time Analysis incorporates turnpoint geometry to determine where the aircraft is

after the point has been passed. Refer to Figures 5-5 and 5-6. During this step, implement a

speed correction as needed to get back to preflight timing. Initiate a speed correction only if the

aircraft is off mission timing by more than 12 seconds.

Turnpoint Geometry. Once again, if you are not directly over the top of a turnpoint, you will

actually increase/decrease the distance the aircraft has to fly to stay on mission profile. After a
