A common recommended minimum average lux level for airport perimeter lighting is 3.5 lux.

Adequate perimeter lighting is essential for airport security during hours of darkness or low visibility. It facilitates surveillance by security personnel and CCTV systems, helping detect unauthorized access attempts across the perimeter. Standards like those from the International Civil Aviation Organization (ICAO) or national aviation security agencies specify minimum illumination levels.

While different standards may exist, 3.5 lux on average is often cited as a baseline requirement for airport perimeter lighting, with consideration for uniformity and avoidance of glare. Option D is incorrect as perimeter lighting is a fundamental security requirement for airports.
