LSI HEEL System
In case of a ditching or a controlled emergency landing over water with smoke development and/or blackout, Astronics LSI’s Helicopter Emergency Egress Lighting (HEEL) system provides valuable visual clues to identify the emergency exits during ditching. The system can be activated by a variety of means including loss of A/C power, water, impact or other. Following a ditching or crash, the system identifies the emergency escape hatches, pushout windows and emergency exits by illuminating their perimeter as required by MIL-85676(AS), JAR OPS 3.837(a)(4) and CAA Airworthiness Notice 27.
