A system for determining and displaying a minimum maneuverable altitude for an aircraft to return to and land on a takeoff runway after takeoff, comprising: a display device responsive to image rendering display commands to render one or more images; a terrain data source configured to supply terrain data; an aircraft characteristic data source configured to supply data indicative of a plurality of physical characteristics of the aircraft; an aircraft flight trajectory data source configured to supply information indicative of current aircraft flight trajectory; an environmental/airport services data source configured to supply information indicative of a plurality of environmental/airport services conditions external to the aircraft, the information comprising at least one of wind speed, wind direction, outside air temperature, atmospheric pressure, runway conditions and ground visibility; and a processing system in operable communication with the display device, the terrain data source, the aircraft characteristic data source, the aircraft flight trajectory data source, and the environmental/airport services data source, the processing system configured to receive and process data from each of these data sources to thereby: determine a rate of change of aircraft maneuverable altitude with respect to change in aircraft heading, determine a minimum maneuverable altitude for engine out conditions, the minimum maneuverable altitude corresponding to the minimum altitude that will support returning to, and landing on, the takeoff runway; determine a terrain clearance height above which the minimum maneuverable altitude may be implemented, and supply image rendering display commands to the display device that cause the display device to render at least: an altitude tape, terrain, the minimum maneuverable altitude on the altitude tape, and a pseudo gate on the terrain that represents a height above the terrain that corresponds to the minimum maneuverable altitude. a display device responsive to image rendering display commands to render one or more images; a terrain data source configured to supply terrain data; an aircraft characteristic data source configured to supply data indicative of a plurality of physical characteristics of the aircraft; an aircraft flight trajectory data source configured to supply information indicative of current aircraft flight trajectory; an environmental/airport services data source configured to supply information indicative of a plurality of environmental/airport services conditions external to the aircraft, the information comprising at least one of wind speed, wind direction, outside air temperature, atmospheric pressure, runway conditions and ground visibility; and a processing system in operable communication with the display device, the terrain data source, the aircraft characteristic data source, the aircraft flight trajectory data source, and the environmental/airport services data source, the processing system configured to receive and process data from each of these data sources to thereby: determine a rate of change of aircraft maneuverable altitude with respect to change in aircraft heading, determine a minimum maneuverable altitude for engine out conditions, the minimum maneuverable altitude corresponding to the minimum altitude that will support returning to, and landing on, the takeoff runway; determine a terrain clearance height above which the minimum maneuverable altitude may be implemented, and supply image rendering display commands to the display device that cause the display device to render at least: an altitude tape, terrain, the minimum maneuverable altitude on the altitude tape, and a pseudo gate on the terrain that represents a height above the terrain that corresponds to the minimum maneuverable altitude. determine a rate of change of aircraft maneuverable altitude with respect to change in aircraft heading, determine a minimum maneuverable altitude for engine out conditions, the minimum maneuverable altitude corresponding to the minimum altitude that will support returning to, and landing on, the takeoff runway; determine a terrain clearance height above which the minimum maneuverable altitude may be implemented, and supply image rendering display commands to the display device that cause the display device to render at least: an altitude tape, terrain, the minimum maneuverable altitude on the altitude tape, and a pseudo gate on the terrain that represents a height above the terrain that corresponds to the minimum maneuverable altitude.
