Role of Helicopter Lighting Parts in Aviation

We’ve discussed aviation lighting when it comes to commercial flight, but what we have not yet gone over are the lighting signals that can be found on helicopters. While a red and green light on a plane might mean one thing, it can signify something totally different on a helicopter. Read on below for more information on the lighting that can be found on helicopters


In aviation, halogen and IRC lamps are used frequently. Halogen lights are light sources that are reliable, can withstand temperatures at helicopter altitudes, and can provide an instant and constant flow of light output". With 6000 hours in its life, the halogen lamp is flicker free and provides first class performance in snow, fog, and other weather. Additionally, their wattage is 30 to 200W with or without a reflector. IRC lamps are lamps that produce 60% of radiated energy from unused infrared radiation. With an IRC lamp, there is less energy that has to be supplied to bring the filament up to its operating temperature. Ultimately, IRC lamps on a helicopter have more of a luminous efficacy, lower consumption of power and a longer life that is twice the standard of halogen lamps. 

While helicopters have their differences in the types of lighting that is utilized, there are certainly many similarities. Both commercial airplanes and helicopters can utilize obstruction lights (OBSL) as well as LEDs to efficiently get things done. LEDs are a favorite in the market because of their superior energy efficiency, safety and low maintenance costs. Not only that, but they can also mitigate the consumption of energy in airfield lighting thanks to their long life and excellent reliability. 

While the lighting and types of lighting that are used on helicopters may differ from that of commercial airplanes, they both abide by the same runway lighting rules. These include such rules that dictate whether or not a landing is available. All available taxiways that are lit with green lights and blue edges, for example, mean that the runway is prepped for landing. When the runway ends at red lights, that indicates that this is where any vessel is barred from passing. Another example of such runway rules are that the centerline lighting must be up to 900m in front of an aircraft tail. This can alternate to a red and white and red color on the last 300m. Non-precision approaches from airplane or helicopters must also be equipped with at least a 720m long approach lighting. 

There are many parts and pieces that make up the lighting systems of helicopters, commercial airplanes, and taxi runways. You can find any and all of those components at RFQ Experts.
