Vital Ideas Regarding Lighting For Heliport

By Paul Wood


Without lighting, airports functionality is disrupted. The airport becomes a risky place during the night since the light is needed for landing planes or planes taking off. Therefore without lighting, accidents could be caused like crashing while landing. Runways should be lit by lighting for Heliport. When putting up or fixing lights, there are laid guidelines and rules that ought to be followed be it on rooftops, ground or elevated heliports. There are codes to be also followed when installing illumination systems on helipads to ensure uniformity around the world.

Approach lightings to indicate the best approach for helicopter touchdown should be installed for guiding the chopper pilot on how to approach the heliport correctly to safely touchdown. Three rows of light should be used in this system in intervals of 30 meters. 90 meters from the takeoff and the last approach perimeter 18 meters long crossbar should be set. The crossbar holds the light at a right angle to lines of the approach light which are at a spacing of 4.5 meters between them.

Installing more light bulbs beyond the cross bar is an important idea too and a space of 30 meters left. Such light bulbs can be flashy or not but ought to be of a different color to indicate that the endpoint is close. Also, a 210m in length is appropriate if the approach installation for a non-precision final approach and takeoff.

For a ground-level heliport, illumination for the Final approach and Take-Off area must be done on the edges, covering the whole area. On the regular, if the area is constructed in a square or rectangular shape, it should have at the minimum, four lights with a 50 meters spacing so that every corner has a light. For other shapes that the Final Approach and Takeoff may assume, the bulbs must be at least 10 and should have a spacing of 5-meter intervals. The lights, of course, is multidirectional and white color.

Pointing lights are usually a vital tool for a safe landing. They differ from the runway light in the sense that they move up and down to show the pilot the specific section on the ground he or she should direct the plane for safe landing. They are usually installed to achieve a wedge shape usually a minimum of 6 bulbs white in color.

Floodlight and perimeter light bulbs are another part of the installation system which is installed in the touchdown and lift-off area. In case the FATO lights are installed then luminescent panel light bulbs should also be used at a spacing of 3m in elevated ones and for the ground ones a spacing of 5m. Green is the color of these lights, and they can be steady with a minimum of 4 light bulbs each side. If floodlights are to be used then, they are placed at 10m intervals on the floor. The light bulbs must be either at the edge or at a maximum of 1.5m away from the touchdown.

Taxiway and Apron installation are very vital without them then the airport installation is not complete. The conventional installation is blue and Omni-directional. Such lightings are usually powered y a 240v low voltage transformer.

The ICAO contains the heliport installation codes and rules. The brightness must be adjustable. Depending on the weather, the lights can be adjusted to suit the condition. To also ensure safety in heliports, the lighting should also be done professionally.
