January 1, 2015 - Leaked AirAsia Data: 8501 Rose As Fast
As A Jet Fighter Before Dropping Straight Down -
At 11,000 - 24,000 Feet A Minute?
"The jet climbed at a speed that would have been impossible for the pilot to have achieved - and then went straight down like a piece of metal being thrown down. ... It's really hard to comprehend...the way it goes down is bordering on the edge of logic."
- Gerry Soejatman, Indonesian Aviation Expert

Leaked radar data has been described today in the Sydney Morning Herald by Indonesian aviation analyst Gerry Soejatman about AirAsia 8501. The Airbus 320-200 carrying 162 people went off Jakarta radar at 6:17 AM local time on Sunday, December 28, 2014, after its last communication with Jakarta air traffic control asking to change course because of thunderstorms. According to investigation analyst Gerry Soejatman, flight 8501 climbed at a virtually unprecedented rate of 6000 ft to 9000 ft per minute, a rate of climb like jet fighters. Mr. Soejatman told the Herald, "You can't do that at altitude in an Airbus 320 with pilot action," meaning such an upward speed was outside what the airliner was built to do. Further he said the AirAsia flight then dropped at 11,000 feet a minute, with speed bursts up to 24,000 feet a minute. Simultaneously, there was an "extremely low ground speed," as low as 61 knots, during the descent. That data is conflicting and confusing, but such a low ground speed would explain how the airliner headed straight down and was found only 6 miles (10 km) from the last radar contact point early on the morning of Dec. 28.

AirAsia chief executive Tony Fernandes questions whether climate change is increasing the intensity of storms and making flights, especially in warm tropics, a greater risk? Also see The Sydney Morning Herald.
