guidance

Missile guidance refers to a variety of methods of guiding a missile or a guided bomb to its intended target. The missile's target accuracy is a critical factor for its effectiveness. Guidance systems improve missile accuracy by improving its Probability of Guidance (Pg).These guidance technologies can generally be divided up into a number of categories, with the broadest categories being "active," "passive" and "preset" guidance. Missiles and guided bombs generally use similar types of guidance system, the difference between the two being that missiles are powered by an onboard engine, whereas guided bombs rely on the speed and height of the launch aircraft for propulsion.

    Guidance

    I come across taps that have failed to grip onto the tap cartidge properly. Can this often be as simple as just tightening the screw to the head or so, or can this sometimes be resolved by cleaning where the cartridge sits or is it just best to change the cartridge?
