Abstract
A radar unit on board an aircraft scans a scan area of surrounding space relative to a runway to detect any nearby aircraft and a unit presents to a pilot an indication of such detection of the presence of at least one nearby aircraft. The technique involves determining: a heading of the aircraft, positions of thresholds of the runway, an orientation of the runway, a maximum relative bearing, a minimum relative bearing, a maximum elevation, a minimum elevation, a slant range for scanning the scan area from the heading, thresholds and orientation, predetermined vertical and horizontal angles of an approach center line of the runway, a predetermined length of edges of the scan area, and the scan commands enabling the radar to scan said scan area using the maximum relative bearing, the minimum relative bearing, the maximum elevation, the minimum elevation and the slant range. The radar unit is an air-air mode radar configured to detect a nearby aircraft that is in flight; and the scan area has at least one vertical area of space which is situated to one side of the runway and defined relative to a center line of the runway.
