My problems are really starting in times I've 200+ airframes in my list simultanously,
Another aircraft with miscode hex Vq-BJX Rossiya Airlines -periodically using two hex (424964-true,424164-wrong).
For me it looks like a fault in the database or the software accesing the database. 424164 is assigned to VP-CFF. If VQ-BJX is shown during reception of hex 424164 there must be something wrong with the database itself or the software accessing the database.
With correct working software and database, during the reception of a particular flight id, from two different hex codes at the same time, the flight id should occur with aircraft data of both hex numbers in the flight history list. With many hours between the two receptions I would say VQ-BJX is in the database with two different hex adresses against it. The different Boing types are supporting this presumption. Hex 424964 is the correct one and 424164 is a false entry which should be exchanged with the data of VP-CFF. Unfortunately VQ-BJX seems indeed repeatingly using false hex of 424164 (either a dodgy or deliberately/unknowingly miscoded box). Nevertheless the type data of the Boeing aircraft(s) is still inconsistent and needs to be checked if both entries VQ-BJX shall be kept.
A one digit variation in HEX address can easily be caused by reception of corrupted data packets. I've about 10 cases per day. Ususally placed in or around the peak times of air traffic.
