A system, method, apparatus, and computer program product for avoiding aircraft collisions with stationary obstacles. The aircraft is provided with a simplified uncluttered onboard display of all objects which are in or proximate to the projected path of the aircraft at its particular altitude plus or minus a predetermined increment, such as 100 feet constituting a hazard zone. The display presents the hazards in that zone in geographical relationship to the position and path of the aircraft. In addition to the obstacles in the hazard zone the display may also present topographical features of the underlying terrain. This information is in the form of a muted presentation of a topographical moving map. As the aircraft approaches a hazard in the hazard zone the presentation of the obstacles or hazards within the zone is enhanced to draw increasing attention of the pilot. When the aircraft arrives at the periphery of a predetermined hazard avoidance maneuver area where evasive action is imperative, the display undergoes a dramatic change. A further feature of the system may give an audible warning in addition to audible directions as to the action to be taken to avoid collision.
