The invention comprises an aircraft ground collision avoidance system which utilizes a flight control computer for monitoring aircraft flight states and calculating preferred aircraft flyup altitudes at which automatic aircraft flyups should be initiated. The flyup altitude is determined by calculating aircraft altitude to be lost during a recovery maneuver from a current aircraft flight state. The invention also comprises an aircraft autopilot for monitoring aircraft flight states and initiating an automatic aircraft flyup when so directed by the flight control computer. The monitored aircraft states include aircraft airspeed, angle of attack, bank angle and velocity. Sensor lag, aircraft load factor and engine throttle position are also considered in determining when to conduct an automatic aircraft flyup.

A method of automatically avoiding aircraft ground collision comprising the steps of: entering a preselected aircraft flight floor altitude in an aircraft flight computer; monitoring aircraft flight states with said flight computer, said flight states including air speed, altitude and flight path angles; calculating by said flight computer the amount of altitude to be lost during recovery maneuver if the monitored flight states, when extrapolated would indicate a loss of altitude; adding by said flight computer the amount of altitude to be lost as indicated by the monitored flight states during the recovery maneuver to the preselected floor altitude to determine a flyup altitude; comparing by said flight computer the flyup altitude to aircraft altitude; and sending a command via said flight computer to an autopilot to commence initiation of an automatic flyup maneuver if aircraft altitude is less than the preselected aircraft flight floor altitude.
