The TEF9980 Status lights are designed to fulfil the latest requirements of CAA UK CAP 437, as well as operator’s needs for products that are cost-effective, reliable, require no maintenance and are applicable for use in all environments. The TEF 9980 Status light is available as a main light and as a repeater light. Both versions are fully monitored, which eliminates the light units’ redundancy need. In combination with Tranberg control system the lights can be set up for automatic test intervals, timeouts for both dim level diagnostics. A status light system should be installed if a condition can exist on an installation which may be hazardous for the helicopter or its occupants. The system should be a flashing red light (or lights), visible to the pilot from any direction of approach and on any landing heading. The aeronautical meaning of a flashing red light is either “do not land, aerodrome not available for landing” or “move clear of landing area”. The system should be automatically initiated at the appropriate hazard level (e.g. impending gas release)
