This is the E-190. And at x-plane.org, I just saw a forum post that they will release this livery soon. a) The SSG planes are no hardcore realism planes. They are certainly more complex than default XP planes, including custom performance settings in the MCDU, which gives some system depth. On the other hand, they do not offer a custom FMS, but integrate the XP default FMS with the SSG custom performance pages. b ) As far as I know, they are constantly working on updates. As you might know, the E-170 has just received a fundamental update.
