NOTE
-
This subclass covers:

- identification of traffic offenders; - indicating the position of vehicles for traffic control purposes; - navigation systems for traffic control purposes, i.e. systems in which the navigation is not performed autonomously by or in the vehicles, but where the vehicles are guided by instructions transmitted to them; - indication of free spaces in parking areas.

This subclass does not cover:

- arrangements for measuring levels and bearings for surveillance and navigation, which are covered by G01C; - radio navigation systems, e.g. for locating, measuring distances or velocity, which are covered by G01S; - details of display instrumentation, which are covered by G09F, G09G

1. This groups covers arrangements, located in the aircraft or on the ground, for controlling aircraft within a traffic environment.

2. This group does not cover arrangements for control of position, course, altitude or attitude of aircraft not specific to a traffic environment, e.g. automatic pilots, which are covered by group G05D 1/00.

3. In this group the following term is used with the meaning indicated: - "traffic" includes traffic on the ground and in the air.
