lights, approach lighting systems, visual approach slope indicator systems, signs and markers, wind direction indicators, ILS equipment, MLS equipment, radar reflectors, anemometers, ceilometers, transmissometers and security fencing."
Each runway was extended by 500 feet (150 m) and 1,700 feet (500 m) respectively, and a 2,000 feet (600 m) stopway

ASDA, Accelerate-Stop Distance Available, is the runway plus stopway
length which is suitable for deceleration following an aborted takeoff.
