- AirAsia boss promises prompt compensation
10pm: Aviation experts suggest QZ8501 may have been flying too slow and stalled, leading to the fatal crash on Sunday.
According to a Singapore Straits Times (ST) report today, aviation expert and editor of airlineratings.com Geoffrey Thomas believes the pilots while climbing in altitude to avoid the storm they were facing may have induced an "aerodynamic stall" similar to the Air France AF447 that crashed in 2009.
The report also cites Indonesian aviation consultant Gerry Soejatman tweeting on Sunday after seeing a leaked photo of the air traffic control screen of the flight, “QZ8501 ended up at 36,300ft and climbing, but ground speed is only 353 knots! Uh oh!"
ST quotes Thomas telling Australia's Herald Sun he thinks the plane is “100 knots too slow for the altitude he is flying at”.
QZ8501 was initially flying at 32,000 feet and contacted air traffic control in Jakarta at 6.12am local time requesting to fly at 38,000 feet and to deviate to the left to avoid heavy clouds.
