A terrain advisory system utilizes stored data representative of terrain and other obstacles in predetermined geographical areas of interest to provide advisory warnings of the proximity of terrain, obstacles and restricted areas as they are approached. When used in a vehicle such as an aircraft, the system monitors the position, altitude, ground speed, ground track and the vertical speed of the vehicle and provides advisory indications of the position and path of travel of the vehicle with respect to obstacles and terrain. Such advisory indications may take the form of voice warnings describing the nature and position of any obstacles, or a visual display showing the position of the obstacles and terrain with respect to the vehicle.

A warning system for warning the operator of a vehicle of the location of obstacles in the path of travel, comprising: means for storing representations of the locations and physical characteristics of obstacles; means for determing the speed, position and direction of travel of said vehicle; means responsive to said storing means and to said determining means for defining safe approach boundaries between said vehicle and said obstacles as a function of the location and physical characteristics of said obstacles and for dynamically altering the sizes and shapes of said safe approach boundary as a function of the speed, position and direction of travel of the vehicle with respect to the obstacle; and means responsive to said determining means and to said defining means for generating a warning when the distance between the vehicle and the obstacle is less than the distance defined by the safe approach boundary. A warning system for providing a warning to the operator of a vehicle a predetermined time prior to a projected impact with an obstacle, comprising: means for storing data representative of the location and boundaries of the obstacles; means for determining the velocity, direction of travel and position of the vehicle; means responsive to said data storing means and to said determining means for defining warning boundaries between the vehicle and said obstacles, said warning boundaries being a function of the location and boundaries of said obstacles and the velocity of said vehicle said boundary defining means including means for dynamically altering the shapes of said warning boundaries as a function of the direction of travel of the vehicle with respect to the obstacle; and means for generating a warning when one of said boundaries is penetrated.
