Mine's about an 11 when cold at the gate, gets to about, oh I don't know, maybe a 16 or 17 warmed up at the hold point. Could stay airborne for 45 mins or so when it's hours were low but these days alot less than that. Doesn't fly much actually but gets out now and then for re-certification. As it's an Airbus, its of course metric.. Love to have one of those Super Jumbos you guys talk about.....
