Helipad TLOF portable lighting

Helipads are often located in hard-to-reach places. Alaska, the Brazilian Amazon or a skyscraper in the middle of a large city – these are just a few examples of places a helipad can be situated at. If a helipad is meant for night operation, it needs to be properly illuminated. In the following article, we will deal with one type of such lighting. Here’s helipad portable TLOF lighting.

Helipad zones

From a birds-eye-view, you will first notice two designated areas – FATO and TLOF. FATO refers to Final Approach and Take-off area. TLOF refers to Touchdown and Liftoff area. Both these areas can be in the shape of a circle, square or rectangle. The TLOF area is placed inside the FATO zone.

Night operation lights

Not each and every helipad is equipped with a full set of lights. But, if a helipad carries out night operation, it must be equipped with basic lights. They include FATO and TLOF lights, wind direction indicator lights, taxiway lights and landing direction indicator lights.

Helipad TLOF portable lights

Portable lighting is easy and quick to install, and it can be installed on various surfaces. When is helipad portable lighting used?

  1. To illuminate temporary helipads,
  2. To illuminate the TLOF area,
  3. To illuminate the landing zone,
  4. To illuminate emergency helipads.

TLOF portable lights optics

Green lights are used for TLOF lighting. They give out an omnidirectional light. LED lights are used because they provide the right light chromaticity and intensity. They are also utterly durable – up to 50 000 hours of work!

TLOF portable lights’ worktime

The worktime of portable lights depends on the light intensity they are working with. They will work for up to 36 hours with the minimum intensity. When it comes to the maximum intensity – 15 hours.

Helipad TLOF portable solar lighting – work modes

Portable solar lights can give out a constant or flashing light. The flash frequency is 30, 60 or 120 flashes per minute. Moreover, one can set a preferred intensity – low, medium or high. The system also provides a from-dusk-to-dawn work mode. These are lights compatible with night vision goggles.


The aforementioned LED lightbulbs provide excellent visibility from a far distance – even up to 10 kilometers. It is particularly important when a helicopter is landing in low-visibility conditions (pouring rain, fog).

TLOF lights’ cases

Helipad TLOF portable lights are exposed to various weather conditions – wind, rain, sun, extreme temperatures. That’s why they need to meet some requirements that will allow them to work constantly even in difficult conditions. All in all, it has a tremendous impact on the safety of flight operations. These are the characteristics that helipad TLOF portable lights should have:

  1. Water resistance
  2. Corrosion resistance
  3. UV resistance
  4. Extreme-temperatures resistance (even from -40°C to 80°C).

Meeting the requirements and standards

Just like any lights used at helipads, TLOF lighting needs to meet the ICAO (International Civil Aviation Organization) regulations, Annex 14. The lighting used in the European Union must additionally be up to the following standards: EN 61000-4-2:2009, EN 61000-4-3:2007/A2:2011, PN-EN 61000-4-4:2013-05, EN 61000-4-5:2014-10 and EN 61000-4-6: 2014-04.
