Enhanced flight vision system for enhancing approach runway signatures

摘要

Methods and apparatus are provided for visually enhancing approach runway signatures on en Enhanced Flight Vision System (EFVS). The EFVS may retrieve a location and an approach course for a runway, display, on the EFVS, a representation of the runway and the approach course for the runway relative to a position of the aircraft, define an area, along the approach course and before a first end of the runway, where the approach runway signature should be located, and visually enhance, on the EFVS, the defined area.

1. A method for visually enhancing an approach runway signature comprising a plurality of runway lights arranged in a predefined pattern on an enhanced flight vision system on an aircraft, comprising:
retrieving a location and an approach course for a runway; displaying, on the enhanced flight vision system, a representation of the runway relative to a position of the aircraft; defining an area, along the approach course and before a first end of the runway, where the approach runway signature should be located; capturing, by an imaging device, an image of the defined area; displaying, on the enhanced flight vision system, the captured image relative to a position of the aircraft and at the first end of the representation of the runway displayed on the enhanced light vision system; and visually enhancing, on the enhanced flight vision system, the plurality of runway lights of the approach runway signature in the captured image, wherein the visually enhancing comprises suppressing noise not associated with the runway lights of the approach runway signature in the defined area.
