PREPARATION
Being able to drop ordnance onto a target depends largely on factors present at the target, factors
which vary from day to day. Because of this variability, you are expected to prepare the following items
for each flight brief.
DETERMINING DELIVERY DATA
The T-45A NATOPS manual contains delivery charts for MK 76 bombs and 2.75" FFAR rockets
(Figure 1). These charts are used to find the correct sight settings and release attitudes for each
specific pattern. Target elevation must be added to the release altitude to find the correct release MSL
altitude.

COMPUTING OFFSET AIMPOINT
To compute an offset aimpoint, you must know the magnitude and direction of the wind at release
altitude (reported or forecast), and the time of fall of the weapon (see Figure 1). For each flight, you
must compute a separate offset aimpoint for each type of run you will be making. The direction of the
offset aimpoint is very simple: it is always directly into the wind. The offset distance (in ft) is given by
the following formula:
D = 1.7 X T X W
