The world of aviation was shocked by the crash of the Yeti Airlines plane in Nepal, even though the weather at that time was sunny. Flightradar24 also 'recorded' the journey of the iron bird before finally swooping to the mainland.
Flightradar24 is an information service in the form of real-time global flight tracking, starting from the place of origin, destination location, flight path, type of aircraft, position, altitude, direction, to the matter of aircraft speed.
Yeti Airlines crashed near Pokhara International Airport, Nepal, on Sunday (15/1) local time. The ATR 75-500 aircraft, registered 9N-ANC, flew from Kathmandu to Pokhara.
Unfortunately, when it was about to reach its destination, Yeti Airlines allegedly experienced a stall or lost lift and dived sharply to the ground. Whereas before, there were no strange reports related to aircraft disturbances. Otherwise, all seems fine.
"The mountains are clean and visibility is good. There is a light breeze and there are no problems with the weather," said Anun Joshi, superintendent of the control tower.
Flightradar24 said Yeti Airlines took off from Kathmandu at 04:47 UTC. The Flightradar24 receiver collected positional data from the aircraft up to 5:05 UTC.
It stated that the last signal received from the aircraft was at 5:12 UTC at an altitude of 2875 ft AMSL. Meanwhile, the height of Pokhara Airport is around 2700 feet AMSL.
"Throughout the flight, the transponder on 9N-ANC sent incorrect altitude and speed data. The rapid change in altitude shown in the chart above (as noted by the different colors on the track) indicates these incorrect values," said Flightradar24.
Furthermore, Flightradar24 revealed that the Yeti Airlines flight stopped transmitting position data seven minutes before the last data from the plane was received. Flightradar24 said the aircraft was still transmitting altitude, speed and Mode S extension data as of 5:12 UTC.
Flightradar24 also downloads and processes granular ADS-B data (several frames per second) to better understand flight data.
"Using historical data from other similar aircraft operating the same route over the last few weeks and the "MCP alt" setting received for this flight, we have removed the incorrect altitude data to show a clearer picture of the flight path."
