Survey on Night Vision Goggles (NVG) and Enhanced Vision Systems (EVS) in fixed-wing operations

On behalf of the Federal Aviation Administration (FAA), The MITRE Corporation is currently investigating the usage of Night Vision Goggles (NVG) and Enhanced Vision Systems (EVS) in fixed-wing operations. Safety for civilian and military aircraft during night operations has been a topic of public and FAA interest for many years. With the expansion of night operations by civilian and military aircraft, the risk of operating in low-visibility conditions presents a complex challenge. Pilots began reporting difficulty seeing LED-illuminated obstacles while making use of aided-vision systems like NVG and EVS in 2008. The narrow spectrum of Light Emitting Diodes (LEDs) and their lack of infrared emissions can, depending on the aided-vision system and the color of the LED, make it difficult or impossible to see the LED while using an aided vision system. The use of LEDs for aviation applications is on the rise due to the increased incentive of reducing operating costs and the passage of the Energy Independence and Security Act of 2007. Though it is understood that the adoption of LEDs is increasing in the aviation domain, the extent to which LEDs are currently used is not known. The use of NVG and EVS is also unknown. This survey will provide a general understanding of the current usage of these systems.

All responses are anonymous and data is aggregated so as to preclude identifying survey participants. Participant identity will not be requested, collected, or reported as part of this survey. If you have any questions or concerns about this survey, please contact either Gaea Payton ( or Jon Brackin ( We greatly appreciate your help.
