Useful And Essential Facts About Helicopter Landing Lights

By Stephanie Howard


For operations at a heliport to move smoothly and safely, there must be a way for pilots to communicate with people on the ground. Pilots also need to receive directions/instructions from the heliport regarding how to land and take off. The instructions are conveyed in the form of lights. Different lights pass different kinds of messages to pilots regarding how to land and take off from a helipad. Here are facts regarding Helicopter landing lights.

The light beacon HP-50/A is one of the crucial lighting fixtures that are set up on helipads. This light beacon is normally made in the form of while flashing light that acts as a distance visual guidance. This beacon is utilized when the ambient light in the area is making it difficult for the pilot to have a good view of the helipad. The FAA requires all helipads to have at least one light beacon.

Light beacons ought to be installed above the helipad or on it. It is more convenient to install the beacon in a raised location. Also, it is vital to make sure that the pilot is not affected by the glare from the beacon light as they approach the helipad. The lamp ought to be made from material that has excellent impact resistance. The materials should also have a high level of transparency.

Apart from the beacon light, the other vital lighting fixture is the approach light. Normally, it produces white flashing light. The light is used to guide the approach of the helicopter as it lands on the helipad. The light is important as it aids the pilot to see the direction of approach. The fixtures can be installed in the outer region of the heliport in one-way or two-way installation. In each group, there must be 5 lighting fixtures of this kind.

Another important light fixture on a helipad is the upright perimeter light. It is customarily set up in an upright position to produce a constant green upright light. Green light is emitted in all directions at night and during the day and with low visibility. The low visibility is necessary to indicate the landing and take off perimeters for the pilot.

The perimeter light shows the pilot which part of the helipad is safe to land on. Landing outside the perimeter lights can be dangerous to both the aircraft and people or buildings in the area. The area outside the perimeter of the helipad is usually not lit, which means that the pilot will have no visibility at all if they decide to land there. The lamp should be able to remain functional in harsh environments.

Every light fixture on heliport should come with high service temperature to avoid malfunctioning when they are needed most. Low service temperature can also lead to the lamps to break down frequently, which makes helipad maintenance more expensive. The material of the lamps should also be of good flammability rating and good aging resistance.

The FAA strictly regulates the kind of lighting features that can be used at heliports across the country. The lights usually remain on most of the duration they are in use. As such, it is important that they have a low level of power consumption. They must also be very efficient, with a long lifespan.
