This module enables the bridge crew to handle the ship in such as way as to maintain the conditions for safe aircraft operations. A SHOL screen layout (Ship Helicopter Operating Limits) gives the operator a real-time graphical display of relative wind, pitch and roll, outhouse, aircraft status, and cones of courses. This layout can display single or multiple landing spots, displayed separately or merged. The operator can instantly apply any SHOL plate, with variation by aircraft type, task, and weight. A SHOL editor enables the creation of a vessel-specific bespoke library. Since SHOL automatically makes what were laborious manual calculations and indicates optimal speed and heading, this module is a valuable addition to the bridge of any vessel equipped with a flight deck.
