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 an engine inlet of an engine 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;
output the captured image data for display at the display device; and
analyze the captured image data by:
identifying a region within the captured image data that corresponds to the engine inlet;
monitoring the engine inlet, based on the captured image data corresponding to the engine inlet;
accessing pixel coordinates of captured image data associated with the engine inlet in a baseline state;
causing a computer-readable memory to store the pixel coordinates corresponding to the engine inlet in the baseline state;
comparing the pixel coordinates corresponding to the engine inlet during operation with the pixel coordinates corresponding to the engine inlet in the baseline state; and
producing a warning associated with the engine inlet based upon the captured image data.
