Abstract
The system enables aircraft movements on runways and taxiways to be guided and a corresponding ground traffic to be controlled. It comprises sensors for detecting pressure variations and which are distributed at known intervals along the routes, each sensor having four linear arms arranged in pairs on both sides of the axis of the route in such a way that the items of data corresponding to the respective times at which the lateral wheels of the aircraft cross them enable, by means of a simple calculation performed by electronic processing of the detected signals, guidance and control instructions to be produced which include: heading deviation (.DELTA. C), speed (V) together with its direction, and lateral deviation (.DELTA. E) and in addition, instructions or orders such as changes of heading, changes of speed, emergency stops and runway turn-offs.
