The Military & Aerospace Electronics take:

19 April 2022 - Internal and external lights perform the same basic function, but external lights need to be much more robust, according to Eric Dahlinger, business development at PWI.

“Withstanding the environmental challenges on the exterior of an aircraft include not only rain, but winds, fog, sand, dust and sometimes in combination”, he says. “External lights may also be subject to additional vibration and temperature extremes that internal lights do not, as well as the ability to accept a level of impact not required inside the passenger cabin. This affects the light covering or lens as well as mounting the light to the aircraft.”

For flight safety and usage, all aircraft lighting must meet rigorous aerospace grade requirements, observes Matt Opisso, Director, business development & strategy at Collins Aerospace. “External lights are designed with a focus on robust components to withstand the many elements of weather conditions and the environment and meet critical specifications to provide safety and functional use to pilots”, he says. “Light lensing and metal bracketry are essential focusses for installation because they maximize the functionality and lighting output.”
