The Held Bearing Calculator (HBC) calculates the bearing required to follow a radial (circular) course of a specified radius.

The user enters the desired radius (in GUs) and the vessel's speed during the manuever and the required bearing is automatically displayed at the bottom of the module.

Optionally the user can enter the arc (partial circle) required in degrees and the calculator will display how many manuevring cycles are required to complete the arc.
