Dear all,
I'm in progress of flight test of my Europa and have come to speed 
performance test. I will need to show the speed for 100%, 75% and 65% 
power settings and for various altitudes.
I have some difficulties understanding what Rotax/Europa means when say
 75% power.
Looking at Rotax power graph you have 75% power only up to about a 
Density Altitude of about 3500 ft.
On the other hand Europa writes about the performance for 75% 
power @8000 ft.
When talking about let's say 75% power, will that be 75% of the max power
 the engine can perform a Sea Level or the 75% of what it can perform at 
the actual Density Altitude?
Trying to attach some graphs, but can't make it work.
