How is a hospital rooftop heliport lit?
The elevated-heliport lights, plus shielding, obstacle lights and standby power for a site that must always work.
A rooftop heliport is an elevated heliport on a building, so it gets the same lights: green perimeter lights not more than 3 m apart, a floodlit surface where night use needs it, and a lit wind indicator. A hospital heliport serves emergency flights and marks its H in red on a white cross. Some national rules, such as UK CAP 1264, also light the cross.
Three things matter more here. Light is kept on the deck: floodlights are aimed down and shielded so they do not glare at pilots or shine into nearby windows. Obstacle lights mark the building and rooftop equipment. And the lighting is on standby power so it works in a power cut.

Frequently Asked Questions
Q1What is a rooftop heliport?
A heliport on the roof of a building. It is an elevated heliport, so the lighting rules for elevated heliports apply: green perimeter lights not more than 3 m apart, a floodlit surface and a lit wind indicator.
Q2What is different about a hospital heliport?
It serves emergency flights, so it must work at any hour and in a power cut, and it sits close to patients and neighbours. The H is marked in red on a white cross, and the lighting is designed for dependability and for keeping glare and spill light off the surroundings.
Q3How is light kept off neighbouring buildings?
Floodlights are aimed down onto the deck and fitted with visors so they do not shine sideways into windows or into the pilot's eyes. Low, inset or shielded edge lights help too. The goal is a bright deck and a dark surround.
Q4Why does standby power matter?
A hospital helicopter may be called at any time, including during a power failure. The heliport lighting is therefore normally put on a standby supply so it comes back quickly. The exact arrangement depends on the hospital and the regulator, so confirm with the project specification.
Q5What other lights are involved?
The wind indicator is lit, and the building and any rooftop equipment or cranes near the approach carry red obstacle lights. A pilot-controlled lighting system can switch the deck lights on from the air, covered in Entry 10.
Q6Which standards apply?
ICAO Annex 14 Volume II covers heliports, and national regulators publish their own requirements, such as the FAA heliport design advisory circular and local building and fire rules for rooftop sites. Confirm against the standard in force and the project specification.

Recognising an AGL system visually is the first step. The next step is knowing how to design, install, test, commission and maintain them correctly.
