The Civil Aviation Authority of Singapore (CAAS) on Monday said there have been no significant delays in aircraft departures and arrivals despite the haze situation in the country.
As a precaution, airfield lights are turned on in the daytime to enhance the visibility of runways.
Changi Airport can allow aircraft to land safely when the runway visual range is more than 550 metres.
But with more stringent measures, aircraft can still land if the visual range is between 300 and 550 metres.
The measures include putting on standby secondary power supply for essential equipment, such as runway lights, and allowing more time between aircraft landings and take-offs.
Authorities said with reduced visibility, some delays and disruptions to aircraft operations, including flight cancellations, could be expected.
If the visual range falls below 300 metres, CAAS said Changi Airport will not be able to accept aircraft landings for safety reasons.
But planes can continue to take off safely, in accordance with each airline's policy.

Judging by this article, it seems that Changi Airport is only capable of ILS Cat 2 landing of RVR 300-550 metres. Well done to the airport controllers and such for a cool handling of the haze situation.
