Vistara A320neo had less than six minutes’ of fuel left before making an emergency landing at Lucknow Airport, India on 15 July.
The flight UK 944 with 153 passengers was travelling from Mumbai to Delhi was diverted to Lucknow around 420km away due to bad weather.
When visibility suddenly dropped above Lucknow, the pilots attempted to head to Prayagraj 30 minutes away. Then after seven minutes into flight the crew decided to fly back to Lucknow as fuel level dropped below reserve.
Flight crew declared a “Fuel Mayday” call, and the weather cleared just enough for the plane to touch down in Lucknow, with only 200kg of fuel remaining – just enough for five to six minutes’ flying time.
Airline urges passengers not to take pictures on flights
The flying time from Mumbai to Delhi is around two hours, but the flight UK944 was airborne for close to four hours after circling over Delhi for an hour before attempting to divert twice.
The flight finally touched down safely in Delhi at around 1.35am after refuelling at Amausi airport, having originally departed Mumbai at 2.40pm.
The Directorate General of Civil Aviation (DGCA) of India, the aviation regulator, had on July 5 asked airlines in India to carry enough fuel to fly to two alternative destinations, factoring in adverse weather conditions in some parts of the country.
