Abstract: A method for automatically determining a potential transmission region, comprising: acquiring multiple binary indications for a direct line of sight between a transmitter and an airborne vehicle respective of multiple geo-positions of the airborne vehicle; acquiring each of the multiple geo-positions respective of each of the multiple binary indications for the direct line of sight; for each one of the acquired geo-positions, determining a layer of access respective of topographical data for the geographical region and the acquired geo-position, as a subset of the geographical region that includes at least one potential point defining a potential line of sight between the transmitter and the airborne vehicle, thereby determining multiple layers of access; determining an intersection of the multiple layers of access; and determining, from the intersection, the potential transmission region respective of the transmitter and the geo-positions of the airborne vehicle.

Abstract: Head-mounted see-through displays and methods are provided which improve helicopter displays and provide more relevant information to the pilot while reducing the information load on the display. Displays comprise a peripheral pilot-scene pitch indication region, indicating scene orientation information according to an orientation of the pilot's head with respect to the scene, a propulsion state indication region, indicating rotor and engines states with respect to their nominal operation states by presenting only deviations of the rotor and engines states from their nominal operation states, a speed indication region, indicating, in association with displayed air speed, a calculated ground speed or a calculated ground speed component in a direction of propagation and a helicopter pitch indication region displaying a pitch ladder which is re-arranged to space close pitch lines and crowd remote pitch lines.
