Surface level heliports are those for helicopters and are located on the ground. They are characterized by usage of large space. The typical heliport has various helipads. These are the areas that are smooth and flat and are devoted to landing and taking off of helicopters. They are normally located near conventional airports but are in lesser-used areas. Helipad lighting is very important and consists of various forms of lights.
Identification of the helipad is very important, which is why beacon lights are used. Provision of the beacons is important in the event that long-range visual guidance is thought to be important. These lights have to be placed in elevated areas so that there is no chance of the pilot getting dazzled at short range. Repeated series of white flashes are emitted by the beacon light. These flashes are spaced at equal intervals. They are in the form if letter H, with the Morse code used.
Beacon lights show at all angles of azimuth, with the intensity being greater than 2500 Cd. The brilliancy control setting should be 3, 10 and 100 percent. Floodlights in helipads are for the illumination of touch down and the area of lift off. These lights are so located as to avoid glare to pilots or the personnel working around the area. The horizontal luminance should be averagely 10 lux. Floodlights also help in illumination of obstacles. Floodlights for obstacles should have a luminance of at least 10cd/m2.
The final approach and takeoff area, FATO, should be very well lit as well. FATO lights are placed at the edge of the FATO. These lights are supposed to be white, steady and omnidirectional. The intensity should be a minimum of 100 candelas. The setting of brilliancy control is 10, 30 and 100 percent. These lights are placed on the edges of the area at uniform spacing.
The touchdown and lift off areas, TLOF, also needs lighting. This is where TLOF lights come in handy. These are green, steady and omnidirectional. Their intensity has to be 30 candelas and more and are placed at the TLOF edges. A distance of 1.5m is left on the edges. For surface-level helicopters, lights ought to be uniformly placed at intervals that should not exceed 5m. Lights that are rectangular in shape should be 12 in number and the circular ones around 14.
The direction of approach is displayed using approaching lights. These are placed on a straight line on the preferred direction. They are supposed to be steady and omnidirectional. They should be flashing in case the helipad cannot be easily identified because of lots of light around.
To approach certain areas before proceeding to the TLOF, aiming point lights should be used. They are white and steady, with an intensity that exceeds 100 cd. Brilliancy control setting is 10, 30 and 100 percent.
Windsock lights help in displaying the windsock and thus enabling the pilot to see the wind direction. At least one direction indicator is required for every heliport. The windsock light used at night needs to be illuminated so that it is easily seen.
