tested to Vd, 10% over Vne. And not just taken to the speed but then teste
d [short stick and rudder raps] to see if any flutter mode could be excited
at Vd. I have performed these tests at/up to 8000ft . We have never experi
enced any flutter mode. I also tested the tail plane underbalanced and over
balanced with the same results. To my knowledge we have not had any report
ed flutter incidence on the entire fleet. As you mentioned Pete did exceed
Vd on a few occasions. =C2-Ivan =C2-From: owner-europa-list-server@matr

Great article Will, thx! =C2-I wonder now how the europa was tested wrt V
ne and if Vd was tested/is specified, if there is a IAS/density altitude ta

I seem to recall a discussion on this but I can't find it on the list. =C2
-At 12000 ft DA at which I was flying today, the difference is between IA
S and TAS is 20 kts or roughly 20%. =C2-Thanks in advance Will
