Abstract

A system includes a camera configured such that a field of view of the camera is positioned to capture a base portion and a movable portion of an aircraft. A computer communicatively connected to the camera is configured to determine a relative orientation between a base identification feature of the base portion and a movable identification feature of the movable portion of the aircraft based on image data received from the camera. The computer is also configured to determine a position of the movable portion of the aircraft based on the relative orientation between the base identification feature and the movable identification feature and a position of the base portion and to compare the position of the movable portion to a reported position for the movable portion to determine a variance. An aircraft control system is configured to monitor a state of the aircraft based on the variance.
