Abstract
Systems and methods for use in generating alerts regarding terrain near an aircraft are provided. A method includes determining a plurality of warnings relating to terrain near an aircraft, each warning indicating terrain above a threshold elevation and having a position associated with the warning. The method further includes, for each warning, generating alert data formatted for display as an alert on a display device of the aircraft within a plan view terrain display screen on or proximate to the position associated with the warning and overlapping a visual representation of a portion of the terrain. The method further includes transmitting the alert data to the display device. A same alert shape is used for all warnings, and the alert areas of the alerts are at least partially transparent, such that the visual representations of the portions of the terrain within the alert areas are visible.
