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.

The selection of the design parameters of a perspective flightpath display must take into account the operational capabilities of the vehicle to be controlled. As a result, designs of perspective flightpath displays that have been optimized for fixed-wing aircraft may need to be modified in order to be useful for advanced approach procedures with tiltrotors. This paper discusses potential changes that are required as a result of the different range of flightpath angles used in approach trajectories and the different range of velocities.
