Different transition altitudes/levels in different world regions

Ah, thank you. I didn’t know that, because in my home country Germany we have 5.000 ft everywhere. But you’re right. Just found an article which says that some countries like France & UK have different TAs per airport, while other countries like Germany and Netherlands have the same TA everywhere.

Perhaps Asobo can make that a variable parameter per airport? I guess Navblue would have that data available?
