Regardless of the circumstances in this case why cant the EU who mandate what size a cucumber must be can come up with a standard transition level ?{as in Canada, F/L 180, which puts the aircraft above the big rocks} some of the transition levels are simply too low given the rate of climb/descent of many aircraft in service in this day and age, it also prevents the QFE holdouts from trying to remove the top 300 feet of the local lumps. {Well not all the time, but it does reduce the chances of hitting a grain elevator as done by a certain exchange pilot a few years back}
Totally agree, We have the Alps and FL180 would be a good starting point. It is ridiculous that there is so much variation.
There was talk from EASA of having a standard transition level then it died a death
