Bearing Rate

Bearing Rate is the measure of how quickly the compass bearing to an object changes over time. Generally, it is measured in degrees per minute, and the object in question is the target.

Bearing rate is a useful metric in fire control because bearing rate and range can be related to gun deflection. In some fire control mechanisms (such as on some Dreyer Fire Control Tables, a bearing rate might be entered into a bearing clock to help maintain an approximate bearing setting on appliances that use this, such as a dumaresq's dial plate.
