bomb sighting systems

1. vector sights--Sighting systemsusing the vector principle and incorporating a mechanical representation of the vectors of the bombing triangle. a. pre-set vector--A sighting system in which the values for height, airspeed and wind are set manually on the bomb sight. b. continuously set vector--A sighting system in which the values for height, airspeed and drift are automatically and continuously updated.
2. tachometric or synchronous sights--Sighting systems which automatically release the bomb at the correct bombing angle by maintaining the sight line on the target, thus determining thespeed relative to the target and in some cases the track throughthe target.
3. angular velocity sight--A sighting system in which the correct release point is determined when the angular velocity of the target relative to the bomb aimer reaches a precomputed value.
