Claim 0:
1. A system for monitoring an external environment of an aircraft, the system comprising:
an aircraft door;
a camera with a field of view toward the external environment of the aircraft and disposed within the aircraft door such that a wheel of a main landing gear of the aircraft is within the field of view of the camera;
a display device disposed within an interior of the aircraft; and
a processor operatively coupled to the camera and to the display device to:
receive image data captured by the camera that is representative of the external environment of the aircraft; and
analyze the captured image data by:
identifying a region within the captured image data that corresponds to the wheel of the main landing gear;
identifying whether the region within the captured image data corresponding to the wheel of the main landing gear includes image data corresponding to the chock block;
monitoring the wheel of the main landing gear, based on the captured image data corresponding to the wheel of the main landing gear;
producing a chocked main landing gear output that indicates whether the region within the captured image data corresponding to the wheel of the main landing gear includes the image data corresponding to the chock block;
identifying an image distance between the wheel of the main landing gear and the chock block;
comparing the image distance between the wheel of the main landing gear and the chock block to a threshold image distance; and
determining that the chock block is present at the wheel of the main landing gear when the image distance is less than the threshold image distance.
