What is the prescribed height of the airport perimeter wall ?

According to the guidelines issued by the Bureau of Civil Aviation Security (BCAS), the regulatory authority for civil aviation security in India, the standard height for an airport perimeter wall is prescribed as 8 feet (approximately 2.43 meters) above ground level. This wall is required to be topped with a concertina coil overhang, typically measuring 1.5 to 2 feet (0.45 to 0.6 meters) in height, usually supported by Y-shaped or L-shaped iron pickets. The total height of the security barrier thus reaches approximately 9.5 to 10 feet. These standards are mandatory for all licensed airports in India to ensure perimeter integrity and prevent unauthorized intrusion into the airside. Option B correctly identifies the 8-foot wall height requirement specified in official AVSEC (Aviation Security) orders.
