|Nature:||Passenger - Scheduled|
|Departure airport:||Warszawa-Frédéric Chopin Airport (WAW/EPWA)|

|Confidence Rating:|| Information verified through data from accident investigation authorities|
The aircraft was flying at an altitude of 1500 metres (5000 ft) AMSL while approaching runway 13R at Budapest when the flight crew detected a glider flying opposite them at a lateral distance of 100-150 metres and at an altitude exceeding their own level by 90-150 metres (300-500 ft). The glider was a single-seated glider type Schleicher Ka-8B, with registration number HA-4007, operated by Malév Aero Club.
The pilot of the glider performed an endurance flight near the upper limit of the airspace permitted for the flight and may not have realised flying through an intensive upstream which lifted the glider a couple of hundred metres higher, and the aircraft thus entered an airspace used by airline flights.
– the affected glider climbed above the altitude limit specified for the given airspace,
– the cause of infringing of the altitude limit was the pilot’s lapse of attention originating in his fatigue.
During the investigation, the IC (investigator in charge) encountered the following phenomenon which is not directly related to the event, but deserves attention from the aspect of flight safety:
– Some of the border lines of the airspaces limiting those flying VFR below the TMA are difficult to identify when navigation is based on visual perception.
