The Passenger and Crew Helicopter Emergency Egress Lighting (HEEL) System is designed to provide an independent, battery operated lighting system which clearly illuminates crew and/or passenger emergency exits whenever water immersion is detected or, at customer option, when the aircraft experiences an excessive force (8g). The system consists of a number of electroluminescent lamps spaced along either the area around the inside airframe of the crew door (for the HEEL System, P/N: 412-942-001/-002) or the area around the passenger window interior of the sliding door(s) (for the Passenger HEEL System, P/N: 412-943-001/-002 and 412-944-001/-002). The system is available in over-water or over-water-and-land configurations. It is JAR-OPS 3 approved.
