KUALA LUMPUR, Dec 30 — A screenshot of radar data from Jakarta air traffic control (ATC) allegedly showing the missing AirAsia Flight QZ8501’s last position has been leaked on the Internet.
According to the leaked data, QZ8501’s last altitude was 36,300 feet, over 4,000 feet higher than what was thought to be its original altitude before it requested a route deviation and went missing.
“#QZ8501 seen by Pontianak Rdr passing Fl363 w 353kts grnd speed, tracking west. Brg 141° frm RAFIS at 52.9NM,” said a tweet by Jakarta-based independent aviation expert Gerry Soejatman, who was among those who circulated the screenshot on his Twitter account @GerryS.
Gerry explained in a separate tweet that QZ8501 was seen by the Pontianak ATC as moving at ground speed of 353 knots, which translated to an air speed of 187 knots.
AirAsia QZ8501 was at 32,000 feet when the pilots requested to fly higher at 38,000 feet to avoid clouds, according to Indonesia’s acting Air Transport Director Djoko Murjatmodjo on Sunday.
The ATC did not approve the request before the plane disappeared off radar, National Transportation Safety Committee head Tatang Kurniadi added.
Indonesian news site Kompas reported yesterday that the ATC had meant to allow QZ8501 to only elevate to 34,000 feet, but could not relay the information before contact was lost.
Indonesia AirAsia’s Flight QZ8501 disappeared from Jakarta’s radar at 6.18am local time Sunday amid stormy weather en route to Singapore from Surabaya.
On board the Airbus A320 jet were 155 Indonesians, three South Koreans, one Malaysian, one Singaporean, one Frenchman and one Briton, comprising 155 passengers and seven crew members.
The plane’s last known position was between the Indonesian port of Tanjung Pandan and the town of Pontianak in West Kalimantan on Borneo Island.
