F-Range Type L-850D/E Style 2 Inset Lights Installation 4. L-850D/E Toe-In Coding Figure 3-1 L-850D/E Toe-In Coding 5. Installation on L-868B Base See Figure 3-1. Refer to the guidelines below for L-850D toe-in coding (threshold/end only). • Toe-in direction for the green side is from the pilot’s perspective on approach. Opposite side (the runway end/red side) is straight. • Position the L-850D fixtures on either side of the runway so that the fixture toe-in points to the runway centerline. See Figure 3-1. Refer to the guidelines below for L-850E toe-in coding. • For military approach applications, there is no toe-in. Toe-in direction is from the pilot’s perspective (the approach end of the runway). • For ICAO applications, the light beam is toed and fixtures must be located on both sides of the runway so that the fixture toe-in points to the runway centerline. The light beam is straight for FAA applications. • Encapsulated (FAA Style) isolation transformers are available for voltage-driven, medium-intensity approach lighting applications. For 210 W, 240 Vac to 31.8 Vac applications, use part number 35C0094. The light assembly is shipped complete, including the lamp, and is ready for installation.
