Abstract
Systems and methods for collision avoidance are disclosed. In one embodiment, a method includes providing a proximity warning system operatively coupled to the aircraft and adapted to monitor a scanning area proximate a selected portion of the aircraft. The scanning area is monitored using the proximity warning system. A ground-based device within the scanning area is detected using the proximity warning system, and a distance between the ground-based device and the selected portion on the aircraft is determined using the proximity warning system. If the distance between the ground-based device and the selected portion does not exceed a selected minimum distance, then a warning signal is provided. In alternate embodiments, the proximity warning system provides a second warning signal distinguishable from the warning signal.
