On 25 October 2022, a Boeing 777-300ER encountered deteriorating weather conditions after initiating a delayed arrival diversion from Singapore Changi to nearby Batam where four approaches were flown and a ‘MAYDAY Fuel’ declared before a landing was achieved. By this time, the fuel remaining was “significantly below final reserve” although the actual figure was not published in the Investigation Report. It was concluded that the mismanagement of weather operational risk by the flight crew involved had resulted in potentially hazardous circumstances created by both the delay in commencing the diversion and a lack of professionalism on reaching its vicinity.
