The Civil Aviation Authority of Singapore (CAAS), working with the Changi Airport Group, has introduced a number of new procedures on June 19 to ensure safe operations at Singapore’s Changi International Airport (WSSS). The efforts are specific to operations during low-visibility conditions resulting from recent severe haze caused by fires set to clear land in Sumatra. An extra one or two miles of separation will be added between arrivals, and the airport will keep runway lights on during daytime operations. However, no arrivals will be allowed when the runway visual range (RVR) falls below 985 feet (300 meters), although departures may continue based on individual company operational specifications.
