MONITORING OF STEERING-ANGLE DURING AIRCRAFT TRANSPORT

摘要

The subject matter disclosed herein includes, inter alia, a method and system which enables to determine the steering-angle between the longitudinal axis of a tractor and the longitudinal axis of an aircraft which is being led by the tractor (referred to herein as “steering-angle” in short). While an aircraft is being led, the steering-angle can be repeatedly calculated and compared to a threshold value defining a mechanical steering limit. In case the comparison complies with one or more predefined conditions (e.g. the steering-angle is equal or smaller the threshold value) a warning can be generated indicating to an operator that the steering-angle has reached (or is about to reach) its limit and should be adjusted accordingly.

1. A method of determining a steering-angle between a leading vehicle and an aircraft;
the leading vehicle is connected to the aircraft and is configured to lead the aircraft on the ground; the leading vehicle comprises a platform and one or more scanners which are positioned on the platform, the method comprising: obtaining scanning information of at one or more scanning planes of the aircraft's underbelly; the scanning information is generated by the one or more scanners; the scanning information of each of the one or more scanning planes comprising a respective group of scanned points of the aircraft's underbelly; determining, for each scanning plane, respective real-time geometric properties; the respective real-time geometric properties including at least data indicative of ranges between scanned points in the respective group and a certain fixed point on the platform; determining, based on the real-time geometric properties, a steering-angle between the longitudinal axis of the leading vehicle and the longitudinal axis of the aircraft.
