Helicopters land on pads or platforms especially designated for them. These areas must have helipad lighting to aid in safe and accurate landing. The landing areas are flat, hard surfaces with clear markings to signal correct information to helicopters in the air.
Landing area lighting is usually arranged in a circle or square around the touchdown and lift-off area, known as TLOF. Around this area is another set of lights that encompasses the TLOF. This is overall area is called the final approach and take-off area, or FATO. The International Civil Aviation Organization, along with the Federal Aviation Administration, recommends that all the lights be white. Years ago, lights were standardly yellow or amber, and are often still preferred in certain places.
The owner and jurisdiction of the pad determine the color. The lights themselves are light-emitting diodes and provide brightness control, though they used to be singularly incandescent. All lighting must be accompanied with a lighting wind cone as well. If needed, the owner may want to add surface flood lights or lead-in lights to the TLOF and FATO areas as well.
Lighting systems can also have visual slope guidance systems such as HAPI and PAPI installed. Although they are recommended by the authorizing organizations, many people don't choose to use them due to the high costs. Lighting systems usually utilize AC power instead of the common 6.6A direct current. Pilots can radio control the lighting as well with an automated ground-based controller.
Many heliports and airports have helipads because they offer fuel, air traffic control, and service facilities that are all useful for aircraft. However, it is very costly to place so many helipads in these areas, and there is often not enough space for a lot. Police departments, however, have specific helipads on both these areas where they can place police helipads. Office towers have helipads on roofs for air taxis or emergency services like evacuations. Oil rigs and naval ships will often have helipads as well for transport and supplies.
MEDEVACs and air ambulances utilize helipads in great amounts while transferring trauma victims to hospitals. Apart from trauma, helicopters are a great and quick way to transfer patients who live in areas without the proper caring hospitals they need as well. In most urban areas, the helipads are located on the roofs.
Some helipads require location identifiers. Authorized agencies in the U. S. That issue these identifiers are the FAA, ICAO, TC, and IATA. If needed, helipads can have more than one identifier that all have different formats and names.
A large letter "H" is usually marked inside a circle and placed right in the middle of a helipad. This way, they are visible high up from the air. Helipads, however, aren't always concrete-based, as forest fire fighters will often build temporary timber ones to receive supplies. Helipads can also be built with rig mats, but only if it can withstand situations like ice accumulation. A rooftop helipad will also provide a two-digit number representing the weight limit, and a second number representing the maximum rotor diameter.
