Haze Impact on Flight Operations at Kuching International Airport

As of 12 AM today, flight operations at Kuching International Airport (KIA) remain unaffected by the prevailing haze, with all flights proceeding as scheduled. No cancellations have been reported thus far. However, a potential for flight disruptions exists if the haze significantly impairs pilot visibility.
Visibility Thresholds for Flight Disruptions

The primary mechanism through which haze affects flight operations is by reducing visibility. While specific visibility thresholds are not detailed, it is understood that a substantial decrease in visual range can necessitate flight delays or cancellations. This is a standard operational consideration for aviation authorities worldwide when air quality deteriorates.
Current Haze Levels and API Readings

The haze situation has seen fluctuations, with the Air Pollutant Index (API) in some areas, such as Sri Aman, showing a slight increase to 236 at noon, up from 229 earlier. Conversely, Kuching's API saw a marginal decrease to 225 from 232, and Samarahan fell to 202 from 213. Despite these changes, readings in Kuching and Samarahan remain at a "very unhealthy" level, generally considered to be between 201 and 300.
Broader Impact on Air Travel

The potential for haze to cause flight delays or cancellations is a recognised issue within the aviation industry. When visibility drops below safety margins required for landing and takeoff, airlines and airport authorities will implement contingency measures. These measures are in place to ensure the safety of passengers and crew, with operational adjustments being made on a case-by-case basis depending on the severity of the atmospheric conditions.
