Flight guidance and navigation display for a helicopter
First Claim
1. A flight guidance and navigation display for a helicopter, comprisinga three-dimensional, semicircular flight guidance and navigation tunnel to display a planned flight path of the helicopter;
- a circular surface, which is integrated in the flight guidance and navigation tunnel, which circular surface comprises a diameter that corresponds to that of the flight guidance and navigation tunnel, for displaying a longitudinal position within the flight guidance and navigation tunnel;
a flight path prediction icon for displaying a position, projected into the future, of the helicopter relative to the flight guidance and navigation tunnel; and
a command signal that relates to the air speed, wherein by means of the command signal a deviation from a reference speed that has been predetermined by flight planning is displayed, the command signal being in the shape of an arrow, comprising a point, wherein if an increase in the speed is required, the point of the command signal is aligned in the direction of the planned flight path, while if a decrease in the speed is required, the point of the command signal is aligned against the direction of the planned flight path.
