Surface level helipads are those that are located at the ground level. Unlike other forms of helipads, they tend to use more space. There are various helipads in a typical heliport. Helipads are smooth, flat and are devoted for takeoff and landing of helicopters. Whereas they are located close to conventional airports, they have to be situated in the lesser used places. Helipad lighting is very crucial and many types of lights are used.
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 edges of the final approach and take off area, FATO, are installed with FATO lights. These are omnidirectional, steady, white and usually have intensity of more than 100 candelas. The brilliancy control is similar to that of beacon lights, that is 10, 30 and 100 percent. These are supposed to be placed at the FATO edges at uniform spacing.
TLOF lights are placed on the edges of the TLOF (touchdown and lift-off area). They are steady, green, omnidirectional and have intensity of above 30 Cd. They are supposed to be placed along the edges of the TLOF. This is done within a distance of 1.5m from the edge. In the case of surface-level heliports, the lights are supposed to be placed uniformly at intervals not exceeding 5m. Rectangular shaped lights should be at least 12, with the circular shaped ones being 14 in number.
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.
