Hover guidance display using perspective objects

A helicopter hover guidance display that uses perspective objects was developed and evaluated by flight and simulator experiments. The display presents the pilot with the position of the helicopter on a horizontal situation (Map) display as well as on the FD (flight director) of a PFD (primary flight display). Several flight experiments using JAXA´s research helicopter confirmed the usefulness of this guidance display. Next, the effects of some key display design parameters on flight director tracking performance and pilots´ subjective ratings-the form of the flight director, field of view and whether the display was head-down or head-mounted-were investigated in a series of flight simulations.
