DEFINITION
Classification: 235/404
Aiming (i.e., gun laying):
(under subclass 400) Subject matter including means to calculate the elevation and azimuth angles to be imparted to the gun in order to hit a given target.
(1) Note. Included in the subclass are means to aim a gun at either a stationary or a moving target, from either a stationary or moving weapon.
(2) Note. Factors taken into account in the calculations when aiming at a stationary target include ballistic factors for the ammunition used, wind factors, the number of times a gun has been fired, the necessary elevation for the shell to strike a target at a given range, etc.
(3) Note. Factors taken into account in the calculations when aiming at a moving target, besides those mentioned in (2) include speed and course of the target, altitude, and the predicted future positions of the target.
(4) Note. Means to calculate the course and roll or pitch angles for airborne weapons fixedly mounted on the airframe are excluded.
