FLIGHT TRAINING INSTRUCTION T-45 WEAPONS/STRIKE - Cnatra

CHAPTER EIGHT T-45 WEAPONS/STRIKE
A good ISP for the 30 and 20 degree patterns is 2 ½ to 3 degrees depressed from your planned
dive angle (32 ½ to 33 and 22 ½ to 23 degrees respectively). For the 10 degree pattern it is
closer to 2 to 2 ½ degrees depressed (12 to 12 ½ degrees).
Just like in the landing pattern, a good start equals a good tracking run which in turn equals good
hits. The fewer corrections you need to make in the dive the more you can scan altitude,
airspeed, line-up, Target Placement Angle at the checkpoint, and pipper placement at release.
This will lead to your hits being grouped closer to the intended impact point.
Finally, the ISP is only valid upon initial roll-out onto the target with minimal loss of altitude in
the roll-in.
Initial Sight Picture, Velocity Vector Placement and Line-Up Guidance
When selecting the A/G HUD Mode, the HUD initializes to the UNCAGED mode. THIS IS A
GOOD THING! In the uncaged HUD mode, the Velocity Vector and pitch ladders show where
the aircraft is actually going. The Pipper, Altitude and Airspeed boxes are fixed locations on the
HUD.
When we release the bomb by pressing the “pickle” button, we are essentially taking the
Velocity Vector and placing it on the bomb. Due to the fact the bomb does not have a Rolls
Royce engine strapped to it set at 94%, it will fall below the Velocity Vector a certain number of
mils (128 mils in our case) due to Trajectory Drop. This is the distinct advantage we have in the
T-45C which is not in the T-45A. We use this for our line-up guidance.
