摘要
A method to improve landing capability for an aircraft is provided. The method includes storing calibrated-offline-reference images of at least one runway in the aircraft and capturing real-time images of a destination runway during an approach to the destination runway. The destination runway is one of the at least one runway. The method further includes comparing the real-time images of the destination runway with the calibrated-offline-reference images of the destination runway to select respective closest calibrated-offline-reference images from the calibrated-offline-reference images for the associated real-time images; evaluating translational differences and rotational differences between associated real-time images and selected closest calibrated-offline-reference images; and determining errors in translational coordinates and rotational coordinates provided by a navigation system in the aircraft during the approach based on the evaluated translational differences and rotational differences.
