An aircraft ground collision detection system comprising: an object detection device for mounting on an aircraft and arranged to detect objects and output the location of each detected object; and a processor arranged to: receive the ground speed of the aircraft and the heading of the aircraft and the detected location of each detected object; predict the aircraft's path based on the ground speed and the heading; compare the predicted aircraft path with the object locations; and output an alert based on the overlap and/or proximity of the predicted aircraft path with the object locations. By predicting the path of the aircraft based on detected ground speed and heading, the system can accurately assess which detected objects pose a collision threat. An object which is in relatively close proximity to the aircraft, but which does not lie on the path will be detected, but the system is capable of assessing that the object does not pose a collision risk. Accordingly, the system can avoid generating an unnecessary alert, thus reducing the false positive count of the system and providing the pilot with more reliable and informative collision information. Fewer nuisance alerts leads to a lower likelihood of pilots ignoring or taking less notice of the alerts and thus decreases the chances of collision. Further, as the aircraft path prediction is only reliant on heading and groundspeed information which is readily available, the system can readily be retrofitted onto existing aircraft in a non-invasive manner.
