Ho there,
I do land very often in EDDF since it is my main hub. What I recognized for some time now: whatever the (live) weather is in the Frankfurt/Main area, whatever winds the METAR says, it’s always very very bumpy in the whole area. Heavy gusts from about 10.000ft and below until landing. The ‘always thing’ is strange to me. Doesn’t happen on any other airport.
It might be a bug? It might be a coinsidence. No idea.
