The predicted impact point (PIP) is the location that a ballistic projectile (e.g. bomb, missile, bullet) is expected to strike if fired.
Modern combat aircraft are equipped to calculate the PIP for onboard weapons at any given time.
Using the PIP marker, pilots can achieve good accuracy at ranges of up to several kilometers, whether the target is ground-based or airborne.
Red dot sights do not use internal computers and must be manually zeroed for maximum accuracy.
In these, machine learning techniques like neural networks can can be used to update the predicted impact point based on the current flight state in a reasonable amount of time and computational resources.
