Back in 2002 I was contracted by Embraer to make some photo coverage of the demo tour around Europe, after the Farnborough Show. Needless to say, I flew many sectors on it, tail number was PP
-XJA, and I was impressed. The seats were similar to the ones seen with the LOT machines.
Confort level was good+, noise was almost non-existant, and the plane perfomed very well, albeit being flown by manual control only and below FL290, as the A/P software wasn't installed yet.
A nice plane and a smooth ride.
