Air Traffic and Airport Administration - Hungary
Since the recent years in Hungary in investigating the incidents, accidents and disasters the Civil Aviation Authority (CAA) at cases where weather possibly involved claims aviational synoptic expertise. These collaborations also enrich general meteorology with airborne experiences never met without hitting it.
Introducing two case studies which are totally different respect to both the synoptic situation, the aircraft type, the phase of flight and the encounter: 1. (August, 1995) in an anticyclon with unstable airmass a Boeing767 international airliner during takeoff encountered a touchdowned microburst from a summer heat thunderstorm just crossed the runway and almost pushed back down onto from a tens of meters height – not happened a disaster (thank to only God!) but the plane’s tail damaged during as just touching the concrete; 2. (July, 2001) in the unstable warm sector of a Carpathian mesocyclon a private six-seat Cessna cruising on 10,000 feet reached close to an embedded Cb-cluster and captured, broken and crashed to the ground by one of its travelling downbursts – all six died and the plane destroyed.
Presenting the synoptical situation and meso/miso-scale patterns using simultaneous analysed and remote sensed fields with special care to tracking the CBs’ formation and movement by radar and lightning detection. Demonstrating the bursts’ dynamic with reconstructing the plane’s movement and track respectively from the flight data recorder and air traffic control radar data. In the case no. 2 on a simultaneous PPI-RHI weather radar indication also the burst itself and from aerial photos its further damaging to the land will be shown.
As the consequence recommending further new vital procedures for better avoiding these severe outcomes.
