I haven't yet purchased the A350 but I've spent plenty of time watching reviews of the plane and everything looks amazing.
Despite this, there is one small thing I've noticed which I find a little underwhelming.
The way the plane reacts when the gear touches down seems abrupt and sharp - there is no bounce/recoil/rebounding effect, it seems very cartoon/videogame-like.
I find this takes away from the realism and dampens the landing experience -I think this would be a really cool and important improvement given the level of automation built into the plane - landing is one of the only times you will hand fly the plane and I think the experience should be as immersive as possible.
Take the PMDG 777 for example - the sounds used and the way the plane shakes and rumbles on landing really makes it feel like you're landing a 250T aircraft.
I'm not sure if It's just me who noticed this, I'd be interested to hear what other people think!
