Aerial vehicle awareness display

A method of displaying information pertaining to an air vehicle is disclosed. Information is displayed indicative of first portions of a map where distance between a current altitude of the air vehicle and terrain in the map are within a first threshold. Information is displayed indicative of second portions of a map where a distance between the current altitude of the air vehicle and terrain in the map are within a second threshold. The first and second portions are updated based on a change in the current altitude of the air vehicle. In another example, a map including a projected flight path of an aircraft is displayed. Location-based information pertaining to radio frequency (RF) status between the aircraft and at least one ground radio is displayed on the map. The location-based information pertaining to RF status is updated based on a change in the current position of the air vehicle.
