3.0 AV-HLI2
The AV-HLI2 is an inset helipad light designed to comply with ICAO Annex 14, Volume II and
FAA EB67D requirements in a compact and low profile fixture. The fixture is available in
TLOF, FATO, ADI & API configurations to fulfil all surface level and elevated helipad lighting
needs.
As an alternative to elevated lights, Avlite’s inset helipad lights are an excellent choice for
locations where elevated lights are not suitable or are at risk of causing interference to
passing aircraft and maintenance vehicles. The lights can be dimmed from 100%–0 to suit
the application and are available with optional infrared (IR) visibility for pilots using night
vision.
The inset helipad lights are compatible with existing infrastructure and come with a simple
plug and play connection making them simple to install.
Note: This installation and service manual must be used in conjunction with the installation
manuals of the following components (where applicable):
• AV-HL-CTRL-T1
• AV-HL-CTRL-T2
• AV-PALC

beam pattern of the heliport light.
• Make sure any nearby obstacles do not impede the lights’ beam pattern.
• When installing, comply with all local electrical code(s).
• Mains power should always be disconnected when work is being done in close
proximity to electrical fittings, and electrical work should only be done by a licensed
electrician.
• Operate the light only within the indicated electrical ratings and product usage
instructions.
• To ensure that the light and peripheral equipment function safely and correctly, use
cable in compliance with the effective local electrical code.
