Yes, so no need for a validation..but have a talk with spanish CAA about the rating..
all european CAA have different feeling about this ..and I share their concerns..
In a SP model, the copilot is not really a full second pilot..plenty of controls remain out of reach for him...that's one of the reason....
I'm not flying Citattion anymore, but I have flown the I,II,SII,V, Bravo,Ultra and Encore..
and by the way, what is the name of this operator ??
Hasta la proxima..compadre
