Tilt

Tilt is the angle formed between the vertical of a shipboard fitting (such as a gun mounting or a director) and that of an idealized reference plane for the ship. These small imperfections in construction require corrective mechanisms for accurate gunnery.

Generally, tilt was only a problem when one instrument (such as a director) had to communicate an angular reading to another fitting (such as a gun mount) which might have a slightly different alignment. The usual remedy was to define a plane of reference for the ship and mount tilt correctors on the directors, elevation receivers and other sensitive instruments so they would "speak a common language" of elevation no matter what their angle of training.
