Spatially Integrated Depiction of Dynamic Trajectories 2001-01-2960
Synthetic vision displays often include a spatially integrated depiction of the planned path. Such a depiction is derived from a set of 3-D waypoints. In situations such as a take-off or a go-around, the optimal vertical profile depends on the energy state of the aircraft, and a precomputed path based on planned waypoints cannot be used. This paper discusses the concept of dynamic trajectories, in which some of the dimensions of the path are made a function of the actual aircraft state. Four potential applications of dynamic trajectories are discussed. The functionality required for these applications has been integrated into a prototype synthetic vision system. Initial evaluations have been performed in a fixed-based simulator.
