Interesting topic. We are actually starting a UPRT centered ATO in Norway this spring. We are in the process of acquiring an Extra 300L.
We have experienced UPRT instructors on board and think we can provide valuable tailored training programs for operators and the private pilot.
Seems to be a niche market without too many providers.
I’m another who wouldn’t be here without URT. As others have mentioned, it is the startle effect that one needs to overcome. If you can think calmly while the spinning ground is rushing at you then you’ll be fine. Everyone should do it.
