Abstract:
1. A method for providing a minimum safe altitude indication on an aircraft display, said method comprising: utilizing current aircraft heading and position data for an aircraft to generate a location and orientation for an own-ship depiction with respect to an aircraft display; utilizing the current position data, along with terrain data, to generate minimum safe altitude data for an area substantially encompassing the aircraft; dividing the area substantially encompassing the aircraft into a plurality of zones based on the terrain data; and displaying on the aircraft display, about the location for own-ship depiction, the minimum safe altitude data for the area substantially encompassing the aircraft including the plurality of zones, wherein a plurality of borders associated with the plurality of zones encompass the own-ship depiction, wherein each border of the plurality of borders is indicative of an altitude associated with a respective zone of the plurality of zones, wherein a shading of each zone of the plurality of zones is indicative of the altitude associated with each zone of the plurality of zones, wherein each of the plurality of zones intersects the own-ship depiction, and wherein the plurality of zones are redisplayed to reflect changes as the aircraft travels.
