In Spring 2012 Debrief received extensions in order to support
The exercise planning tracks are generated in a new track-like entity. This new entity has an origin and a start date/time. These provide a quick way of changing the location and/or the start time for a set of vessel runs. The legs generated for a track represent straight line legs for a platform. Each leg is stored according to a demanded course and a leg-length. Leg-length is specified according to one of these calculation models:
The time travelled along the leg is deterlimed by the time leg length (range) / speed
The leg length is determined by the distance travelled in the specified time at the specified speed
The speed along the leg is determined by the speed necessary to travel the specified distance in the specified time.
Thus, changing one of the two named parameters will result in the third parameter getting a calculated value.
