my 767 seems to have a problem, I can't make her climb over FL260. She always stall at that altitute. oh I'm using the V/S mode with +1500 feet climb rate, althought reduce to +500 feet won't solve the problem. What did I do wrong?

Do you use indicated airspeed? You also have to look into the outside temperture; if its warmer than about - 40 degrees C then it's to warm at FL260.Finally, what T/O weight do you set? With the default value of 246 000 lb the aircrafts ceiling is about FL320 with full fuel.If this doesn't solve it, give us more details.Regards,G

Are you using the PIC airfile or Posky's? I had the same problem with the Posky airfile but if you merge it using Lee's merge file, it flies great!

I had the exact same problem and I can only second on Flic74's reply. Do a PIC/POSKY merge and you'll be fine and dandy.. :-)Regards
