TLOF zone lights

The lighting used at helipads needs to meet an array of requirements set by the International Civil Aviation Organization. The safety of night flight operations depends on the lighting. Since LED lightbulbs started to be used, there’s been a revelation in airport and helipad lighting thanks to the use of solar lighting. Stay with us and find out what it was all about. Today, we want to elaborate on helipad solar lighting – TLOF zone lights.

Airport solar lighting– not only in case of a malfunction

Before LED lights were introduced to the market, airport solar lighting was used as an emergency solution – in case of the main system malfunctions or temporarily – for instance, during maintenance works of the main system. LED lamps not only work very long (will be discussed in more detail later) but also allow for the proper light intensity. Thanks to that, solar lighting started to be implemented as a permanent lighting solution at some airports and helipads.

Helipads – zones

One can notice a few different zones designated within a helipad. Among them, the most important are the TLOF area (located in the central landing area) and the FATO zone that surrounds TLOF. TLOF refers to Touchdown and Lift-off area. FATO means Final Approach and Take-off zone. Both the zones can be in the shape of a circle, rectangle or square.

Helipad lighting

Helipads that carry out night operations need to be properly illuminated. Not all of the helipads are equipped with a full set of lights but the following areas must be illuminated obligatorily: The FATO zone, TLOF area, wind direction indicator and taxiway.

TLOF zone lights

At least four green and omnidirectional lights are used to mark the TLOF area. If the area is in the shape of a square or rectangle, the lights need to be placed in the corners primarily. The distance between the lights depends on a helipad type. It is 3 meters for lifted helipads and 5 meters for ground helipads. The lamp cases cannot stick out above the helipad surface for more than 25 meters. If there is a threat of a collision with a helicopter, they need to be installed flat with the surface.

The optics of TLOF zone lighting

A fully-charged solar lamp will work for up to 85 hours if it is using its lowest-intensity level. If it is working in a maximum-intensity mode, the lamp will sustain 25 hours of work. The lifetime of LED lamps reaches 50 000 hours. Also, the lamps are equipped with an exchangeable optic warhead.

Resistance to external conditions

One needs to notice that the lamps used at helipads are highly exposed to external conditions influences. Therefore, they need to meet special requirements:

  1. Water resistance (IP-65 level),
  2. UV resistance,
  3. Extreme temperature resistance.

We should stop at this point for a moment. The standard lamps used at the TLOF zone can withstand temperatures from -20°C to 50°C. However, the so-called arctic set can work in temperatures from -40°C to 80°C.

Charging options

When it comes to solar lighting (especially airport solar lighting where reliability is of primary importance), this one question always arises: what if there are bad-weather conditions? The newest solutions prove that the weather is not a problem anymore. Helipad lighting (including TLOF zone lights) can be charged in three independent ways. The first one is, of course, a solar battery. If needed, the lamps can also be charged by a charging station that is included in the lighting set. Finally, each lamp can be charged with an electric power grid.

Control and monitoring

Both control and monitoring of TLOF solar lighting can be handled remotely. The range of the remote control is 3 kilometers, and it can be optionally extended. It is possible to control the lighting both from the air and from the ground. Either a pilot or an airport crew member can be the operator. The system is equipped with an emergency on/off switch and an automatic light intensity control system. It adjusts the light intensity level if the battery level is low.

Parameters – compatibility with regulations and norms

Both the parameters and the way the TLOF lights should be installed are determined by the International Civil Aviation Organization (ICAO), Annex 14. Moreover, the lighting used all across the European Union needs to meet additional norms: 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, EN 61000-4-6: 2014-04.

SP-401 – Final Approach and Take-Off area LIGHT

SP-401 FATO light is a key element of solar heliport lighting system. This is a solar-powered intelligent wirelessly controlled helipad light. ICAO-compliant LED optics generates correct light output in terms of intensity and chromaticity. It is NVG compatible LED helipad lights which is often required by military customers.

Helipad FATO lights

Helipads are often located in hard-to-reach places where electricity supply is hindered or there is no electricity at all. In such cases, solar lighting works out perfectly. It does not require electricity, and a fully-charged battery can sustain long hours of work. The reliability of such lighting, in line with low maintenance costs and easy installation, make it a good temporary or permanent lighting solution. In the following parts of this article, helipad solar lighting – FATO lights will be presented.

FATO area

The FATO area refers to Final Approach and Take – off area. It is in the shape of a circle, square or rectangle; TLOF zone is designated within this area. This refers to Touchdown and Lift – off area, but it is going to be explained in greater detail some other time. The regulations say that the FATO area should be at least 1.5 times longer than the length of a helicopter. If a helipad is meant for night operations, the following zones should be illuminated: the FATO area, TLOF zone, taxiway and wind direction indicator.

FATO area lighting

The final approach and take-off area needs to consist of at least four white lights which are omnidirectional and give out a 100-candela-intensity (cd) light. They are installed at equal intervals, and the distance between particular lights should not exceed 50 meters. If FATO is dimetric, the lights are put in the corners primarily. Light cases cannot stick out above the helipad surface more than 25 centimeters. Furthermore, if there is a collision threat, they should be installed flat with the surface.

Helipad solar lighting

As mentioned in the introduction, solar lighting is used in places (but not only) with hindered electricity access. Does it do its job equally well as a conventional lighting? Is it as reliable? How does it work and what makes it special? Let’s provide answers to these questions.

FATO area solar lighting

The lights used for FATO lighting are a key element of the entire system. Just like all of the lights used in aviation, FATO lights need to meet the ICAO regulations (International Civil Aviation Organization). Moreover, the use of LED lights allows for the proper chromaticity and intensity. Also, they are compatible with night vision devices so they can be used by military helipads too. The best FATO lights can be powered by three independent power sources (a solar battery, charging station, electric current).

The most important features of FATO area lighting

Helipad lighting, including FATO zone lighting, is exposed to many external factors so it needs to meet an array of requirements (some of them are optional but recommended):

  1. Light-intensity regulation options: 10%, 30% and 100%,
  2. Two work modes: constant and flashing,
  3. Night vision devices compatibility,
  4. Exchangeable optical warheads,
  5. Remote control,
  6. Battery exchange that can be handled by the user,
  7. Quick and easy exchange,
  8. IP – 65 water resistance,
  9. UV resistance,
  10. Fragile mounting, which will break in the event of a collision and prevent aircraft damage,
  11. Compatibility with ICAO, Annex 14 regulations

The lights’ resistance to extreme temperatures

Special attention should be paid to solar lights’ (including FATO lights’) resistance to extreme temperatures. Standard lights can work in temperatures between -20°C to 50°C. Special lights are capable of working in temperatures from -40°C to 80°C.

Examples of FATO area lighting

Talking about Helipads’FATO solar lighting, one should take a closer look at a particular example of such a light. How long can it work after being fully-charged? What is the lifetime of the lightbulbs, and what protection does it include? Let’s see!

  • The minimum-intensity mode work time: 85 hours
  • The maximum-intensity work time: 25 hours
  • LED lightbulbs’ lifetime – 50 000 hours
  • Charging options: solar panel, charging station, electric current
  • Prevention from overcharging and complete discharging.

FATO lights control and monitoring

FATO solar lights can be controlled remotely both from the ground or the air. A pilot can also be the operator. Wireless range is 3 kilometers, and it can be extended if needed. Moreover, the system provides an automatic lights control and an emergency on/off switch.

European requirements

Solar lights used for Helipads’ FATO area lighting in Europe must meet the following requirements: 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, EN 61000-4-6: 2014-04

SP-401 – runway edge LIGHTs

SP-401 runway edge light is a key element of solar airfield lighting. This is a solar-powered intelligent wirelessly controlled runway light. ICAO-compliant LED optics generates correct light output in terms of intensity and chromaticity. Runway edge lights color is white (clear).

SP-401 is powered by a standard deep-cycle battery which can be stored locally. Separately installed solar-panel supported by maximum power point tracking ensures high-speed charging.

solar runway lighting as permanent AGL

S4GA offers a complete ICAO compliant runway lighting system with individual light control & monitoring. Runway edge lights are powered by solar energy and connected wirelessly – no cables, no CCRs, no transformers are required.

Unlike similar solar products from other airfield lighting manufacturers, our airport runway lights are a complete alternative to conventional cabled RWY lights and can be used as permanent (fixed) AGL. It is applicable as PERMANENT solution for

  • non-instrument runway lighting
  • non-precision instrument runway lighting
  • landing strip lights
  • aerodrome lights
  • LIRL runway lights (low intensity runway lights)
  • MIRL runway lights (medium intensity runway lights)

It is also applicable for temporary usage at big international airports with HIRL (high intensity runway lighting) as backup runway lighting during repair works and in case of electricity cuts.

cable or solar?

Key advantages of solar powered runway lights against cabled system are as follows:

  • cost-effective –  requires 2-5x less investment than conventional (wired) lighting
  • time-saving – it can be deployed 4x faster than wired lighting
  • maintenance-free – annual maintenance is less than 5% of the cost of the system

SP-401 THRESHOLD LIGHTs (runway end lights)

SP-401 runway threshold lights (runway end lights) are ICAO compliant intelligent aviation lights powered by solar energy. Special LED optics generates correct light output in terms of intensity and chromaticity. We use high quality LED with lifespan 50.000 hrs.

Runway threshold lights are powered by in-built deep-cycle batteries providing up to 60 hrs of operations. We use standard batteries available everywhere. Separately installed 20W solar panel supported by maximum power point tracking ensures high-speed charging.

TYPICAL APPLICATIONS

  • Primary/temporary runway threshold
  • Primary/temporary displaced runway threshold
  • Back-up threshold lights (in case of primary system failure)

Encoded wireless control and monitoring of SP-401 threshold light is using radio transceiver and sensitive antenna. External switch and battery level indicator is available. Frangible mounting is used to fix SP-401 to concrete or asphalt surface.

Runway Threshold Lights

Runway threshold lights and runway end lights – apart from runway edge lights – are the most important lights an airport is equipped with. They allow a pilot to identify the beginning and end of a runway. The color, intensity and layout of the lights are strictly determined by the regulation of the ICAO (the International Civil Aviation Organization), Annex 14.

Threshold lighting in airport

Threshold lighting in airport are to be found at the same place runway edge lights are placed. The exceptions are non-instrument runways and non-precision approach category I runways (which will be discussed below), and wing bar lights. Threshold lights are installed symmetrically on both sides of a runway centerline. They are installed no more than 3 meters behind the end of a runway, in the threshold line.

Threshold lights and a runway category

When it comes to non-instrument runways and non-precision approach category I runways, the number of threshold lights is dependent on their even layout in-between edge lights. As for precision approach category I and II runways, threshold lights are installed at 3-meter intervals. These lights are green and uni-directional.

Runway End Lights, End of Runway Lights

Runway End Lights are green in an area an aircraft starts landing. In turn, they are red in an area an aircraft should finish landing operations. These lights are installed in the same binding threshold lights are put in. Thanks to the light, it is easier for a pilot to identify both the beginning and end of a runway – especially if it is hard to distinguish a runway from the background, e.g. when surrounded by other lights.

Runway End Identifier Lights

Runway End Identifier Lights (REIL) that are put on both sides of a runway constitute an additional help for a pilot. They are installed about 10 meters away from edge lights. These are two lights that give out synchronic flashes; the intensity is from 60 to 120 flashes per minute. Their light is omnidirectional or in the direction of a runway. The ICAO regulations recommend using runway end identifier light mainly at non-instrument runways and in the case of a displaced threshold. Ask us about “runway threshold identification lights“.

Displaced Threshold Lights

A displace threshold or DTHR is a runway threshold located in a different place than a runway’s actual beginning or end. It occurs most often in places with obstructions that hinder a safe conduct of flight operations. Also, it is installed in order to minimize the noise. A displaced threshold is marked with edge lights.

Stopway Lights

Stopway is an area at the end of a runway that is used by an aircraft to stop in the event of an interrupted take-off. The lights (stopway lights) that designate that area are turned on in tandem with runway lights. They give out a one-direction light and their layout is the same as that of runway edge lights. The color of lights is red.

Precision Approach Path Indicator

PAPI lights (precision approach path indicator lights) is a key part of airfield ground lighting system used at airports, aerodromes and airstrips. This is a type of visual aid on a runway that helps pilots to maintain the correct approach and land the airplane safely. It warns pilot about too high or too low approach.

S4GA offers portable and stationary PAPI. Compact robust design and simple construction allow fast and easy deployment of PAPI system on the airfield. S4GA PAPI modular ihn design and features Interchangeable PAPI projectors, facilitating low cost maintenance of the airfield installation. The option of servicing PAPI projectors in the workshop means minimum runway shut-down time. Re-lamping projectors is also a very simple task. The cost of life of the PAPI system is the least expensive on the market.

PAPI slope angle is set quickly and simply using three legs. The front legs of the PAPI level the unit laterally whilst the rear leg provides the elevation adjustment. Corrosive resistant construction using light alloys and stainless steel make S4GA PAPI a robust device. The simple design and optical efficiency make this a first class choice of PAPI for the international aviation world.

Solar-powered PAPI

S4GA Solar PAPI lights requires no electrical grid and are powered by solar energy. S4GA wireless control offers instant activation. Solar powered PAPI requires no CCRs, no transformers, No Cables. Installation of solar PAPI takes not more than one day. No energy consumption means – ZERO electricity cost.

Solar PAPI requires a simple, standalone solar engine. No integration into a complex electrical infrastructure is required. Minimal wiring between the PAPI source reduces or eliminates the need for conduit, cabling or trenching for quick deployment and minimal to no runway down time.

Solar PAPI gives Airport indepedance from electrical grid. PAPI is powered by solar engine resistant to the most rigorous weather conditions – from hot African desert to frosty Antarctica climate. PAPI light system is remotely controlled and can be easily integrated into existing AGL.

papi  /  a-papi

S4GA offers 2 types of PAPI airport lights:

  • PAPI – is a bar of four lights which are usually located on the left side of a runway. It is also possible to install 2 bars on the both sides of the runway
  • A-PAPI is the same as full PAPI but it has two lights instead of four

papi aviation lights key features

  • Azimuth Range: + or – 10 degrees
  • Vertical Adjustment: up to 10 degrees
  • Transmission: 2 minutes of arc
  • Filter Transmission: 25%
  • Meets both ICAO and FAA performance specifications

SoLAR Wind Direction Indicator

Airport Windsock (or Wind Cone, Wind Direction Indicator) is a device which helps pilots to identify the direction and speed of the wind. WDI is a conical tube made of textile and mounted on the stick with appropriate heigh.

Wind Cones are usually installed in the central part of the airfield near a runway. Windsocks can be of different colors preferably white and orange or red. White and orange stripes indicate the strength of the wind. Longer windsock – stronger wind. White and Orange stripes show the speed or strength of the wind.

Windsock should be illuminated if airport provides night flights.

WDI can be of different height and size. It depends on manufacturer specification, length of runway, category of airport. However, it should meet standards provided by ICAO or FAA. According to ICAO Annex 14, the length of airfield windsock should be at least 3.6 m and of 7.4 m heigh.

Solar powered wdi

S4GA offers ICAO and FAA compliant illuminated wind directional indicator  powered by solar panel. Solar WDI can be optionally integrated with ALCMS (Airfield Lighting Control and Monitoring System) which allows airport personnel to remotely control illumination od WDI from the Tower.

S4GA Wind Direction Indicator is easy to install and requires no special devices for assembling and mounting.

ICAO Annex 14 Recommendations for WDI

 HEIGHT:   The wind direction indicator should be in the form of a truncated cone made of fabric and should have a length of not less than 3.6 m and a diameter, at the larger end, of not less than 0.9 m. It should be constructed so that it gives a clear indication of the direction of the surface wind and a general indication of the wind speed.

COLOR:   The colour or colours should be so selected as to make the wind direction indicator clearly visible and understandable from a height of at least 300 m, having regard to background. Where practicable, a single colour, preferably white or orange, should be used. Where a combination of two colours is required to give adequate conspicuity against changing backgrounds, they should preferably be orange and white, red and white, or black and white, and should be arranged in five alternate bands, the first and last bands being the darker colour.

SP-103 – taxiway lights

S4GA taxiway lights are solar powered aviation lights applicable for taxiways. They are almost free of maintenance: no cables, no CCRs, no transformers are required. The lights are connected wirelessly via mesh network. AGL has individual light control and monitoring system.

In taxiway lights – as well as in other airport lighting products – we use special ICAO-compliant LED optics which generates correct light output in terms of intensity and chromaticity.

SP-103 is powered by in-built deep-cycle battery providing up to 105 hours of operations. It can be powered by solar panel, charging station or stationary cable. Separately installed solar panel supported by maximum power point tracking ensures high speed charging.

With SP-103 you can easily exchange old taxiway lighting to a new solar powered system; or you can illuminate new airfield with solar TWY within few days.

Taxiway Lights

Airport taxiway lights designate a route that an aircraft uses after exiting a runway. A taxiway leads to facilities, such as hangars, airport aprons or terminals. Its surface is usually tarmac or concrete. However, minor airports can be equipped only with a grass or gravel runway.

Runway taxiway

High-traffic airports that require a quick exit of an airplane from a runway are usually called rapid – exit taxiways or high – speed taxiways (runway taxiway lamp). They are most often created by prolonging a runway, which gives more breaking space. The speed an aircraft can go on a taxiway is from 37 to 56 km/h. Runway and taxiway lighting differ in terms of colors so as a pilot can easily tell where they are at the moment.

Taxiway lighting

Taxiway lighting consists of edge lights, centerline lights, clearance bar lights, runway guard lights and stop bar lights. Taxiway Lights Colors are different (ex. blue) depending on a place they illuminate and what information they convey to a pilot.

Taxiway Edge Lights

Taxiway Edge Lights are a staple element of taxiway lighting. These are blue lights. They are set out on the edges of the entire taxiway, at intervals that do not exceed 60 meters.

Taxiway Centerline Lights

A taxiway centerline is marked with green lights. They are installed at 30-meter intervals, a few centimeters on the left or right-hand side of a centerline.

Other taxiway lights

Besides basic taxiway lights, i.e. edge lights and centerline lights, there are also other lights that constitute an additional help for an airplane pilot. These are, among others, clearance bar lights. They consist of three yellow lights. Moreover, there are also runway guard lights installed on both sides of a taxiway; they give out a yellow, flashing light. Stop bar lights are also installed at airport taxiways. These are omnidirectional, low-intensity, red lights set out in a line.

Installation technique

Operating a large aircraft on the ground is sometimes a much bigger challenge for a pilot than navigating in the air. Therefore, taxiway lights are installed flat with the surface so as they do not pose any collision threats to an aircraft.

Solar Taxiway Lights

Taxiways, just like any other areas of an airport, can be illuminated with solar lamps. The use of LED lightbulbs not only provides a proper light intensity but also – such lights can work up to 60 000 hours!

Airport solar and conventional lighting

Even though it wasn’t a long time ago when solar lighting was used as a backup or temporary solution only, currently it can be successfully used as the permanent lighting solution as well. Its maintenance is nearly costless. It does not require a wire installation, transformers or constant current regulators (CCRs). The lamps work wirelessly and are operated by a remote control and monitoring system. The lightbulbs that are used in solar lighting meet the ICAO requirements regarding light intensity and light chromaticity. The lights can be powered in three independent ways: via a solar panel, charging station or directly from an electric power grid. Each lamp can be charged individually.

Pilot activated lighting

Airport lights, especially runway and taxiway lights, are meant to support a pilot during flight operation. In the case of some airports, hiring operators for such lighting would be cost-ineffective. This is where pilot-controlled lights come into play.

S4GA solar airport lighting is pilot controlled lightning system which combines solar autonomy, remote monitoring, robust design and long service life. Solar powered AGL is designed for permanent applications.

UR-201 – COntrol & Monitoring Unit

UR-201 Control & Monitoring Unit is designed to provide users with ability to remotely control and monitor S4GA solar airfield lighting. UR-201 offers three ways to control runway lights:

  • Manually – using switches located in the control unit.
  • Via radio – using the frequency programmed by the producer
  • Via a mobile phone (phone call or a text message) – a pilot chooses the operator number which activates the system remotely. It should be added that the system is set to the recognition of the authorized phone numbers only.

integration with existing systems

UR-201 module allows for easy integration of S4GA pilot controlled lighting system with existing control interfaces. This means that User would be able to activate entire airfield lighting (runway, taxiway, windsock, PAPI) by using only one device.

remote system diagnostics

Thanks to UR-201 module – S4GA engineers could perform remote system diagnostics and troubleshooting. UR-201 is equipped with USB and LAN ports. LAN port allows for connecting UR-201 module to the internet (which is required to perform remote maintenance). USB port is used to update UR-201 software in case if internet access is unavailable.

What is a pilot-controlled lighting system?

Pilot controlled lighting is a system that allows for activation and control of airport lighting by an airplane pilot. It includes the approach lighting system (ALS) wind indicator lights, runway edge lights and taxiway lighting. At some airports, one can also control the aerodrome beacon.

Where are pilot-controlled lighting systems used?

Pilot controlled lighting systems are used most often at low-traffic airports or airports that are not equipped with an air traffic control tower. At such airports, it would be uneconomic to keep the lighting working for the entire night or hiring special personnel to operate the lighting. Thanks to the use of pilot-controlled lighting, the lights are turned on when needed only. Doing so, one lowers energy consumption and minimizes light pollution.

Solar pilot-controlled lighting

Solar lighting is often used at airports that are located in places where there is no electricity access or it is hindered. Such lighting can be also controlled by a pilot. Such a solution combines reliability, long durability and the comfort of remote control.

Pilot-controlled lighting user authorization

As already mentioned, pilot-controlled lighting systems are protected from unauthorized uses. Therefore, only Administrators and Users have access to using it. Only Administrators can authorize Users and adjust the system settings. Both Administrators and Users can monitor the system in real time and receive automatic alarm notifications.

Pilot control

Pilot-controlled lighting systems also allow an operator to monitor the system in real time. They can choose one of the following ways:

  • Computer interface
  • Sending a technical text message (as a response to such a message, an operator will receive a short technical report regarding the lighting system status)
  • Automatic alarms. The user will receive an automatic alarm text message in the event of an emergency. For instance, if a battery level of any of the lights goes below 20% or a light stops working. In that way, an operator can react and prevent any threats that a lighting system malfunction can cause.

Integrating with the current system

The best lighting systems allow for integrating a pilot-controlled lighting system with the current lighting system. Doing so, a User can activate the lighting of the entire airport (taxiway, runway, wind indicator and PAPI (Precision Approach Path Indicator) with the use of just one device.

Remote diagnostics

Pilot activated lighting systems allow for remote diagnostics and technical problem-solving. The units are equipped with USB and LAN ports. The LAN port provides the module with Internet access, which enables remote maintenance of the module. The USB ports are used for module upgrades if there is no Internet access.

OCT-401 – ChARGING STATION for solar airfield lights

OCT-401 stationary charging station is designed to re-charge SP-401 solar powered airfield lights. OCT-401 can charge up to ten aviation lights simultaneously. Charging station is required to be connected to a standard electrical socket. It can operate on both 110 or 230 VAC. Charging time is 7 hours for completely discharged battery.

Key Features

  • Universal AC input / Full range
  • Protections: Short circuit / Overload / Over voltage / Over temperature
  • Forced air cooling by built-in DC Fan
  • Built-in fan ON / OFF control

Why does S4GA support solar AGL with charging station? Our customers often ask us – what happens with solar-powered airfield lighting system in case of a long period of sunless (cloudy) weather. Solar panel is used NOT to power BUT to charge the battery so there is no risk of system being inoperative during the night time. Assuming “worst case scenario” we can’t always rely on sunshine availability. Therefore S4GA system offers two additional ways to charge airfield lights (apart from solar-based charging). (#1) Charging station, (#2) Stationary cable ( light can be connected to electrical grid that provides 24V, 1.5A DC power).
