Like in most of these places, I reckon nobody minds if you call up in English. Most pilots in Austria, Germany and Switzerland have English RT and English LP.
A small trip report I made for LOIJ:
Great trip report, thanks for sharing!
That’s a super report, THY 
I often wonder what those ski places are like in the summer. I’ve just come back from Madonna and there a lot of the lifts are running.
I’ve known some Germans who do day trips to LOIJ to ski. I’ve just checked the ski map and make sure there are some easy runs and on one of them everything seems bright red or black but this one looks better.
