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. |
