The TEF9980 Status lights is designed to fulfil the latest requirements of CAA UK CAP 437, as well as operator’s needs for products that are cost-effective, reliable, requiring no maintenance and applicable for use in all environments. The TEF 9980 Status light is available as a main light and a repeater light. Both versions are fully monitored, which eliminates need of redundancy light units. A status light system should be installed if a condition can exist on an installation which may be hazardous for the helicopteor 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”
