Determining The Aim Off Point (AOP)
The correct roll out sight picture is accomplished by aiming the top of the HUD so that you get a specific relationship between these three points…the top of the HUD, the target, and the sight reticle. The proper picture varies slightly between aircraft, but not by much. Your basic objective is to roll out with the target about mid way between the top of the HUD and the sight reticle. Here is what it looks like again:
Airspeed Control
Airspeed in the sim seems to affect where the bomb goes. Being \"slow\" seems to result in the weapon landing short of the target, and being fast seems to result in a long impact. This means we need to control our speed in the delivery. I suggest a release speed of 350-400KIAS for the A-4, 400-450KIAS for the F-100, and 450-500KIAS for the F-104 and F-4.
