Brilliant paint Sam! Love that alot.
When your told to climb to a FLIGHT LEVEL you change your pressure to 1013mb.
When your told to decend to an ALTITUDE you will be given a regional QNH so change your pressure to that.
And Tawn - Your pressure could be set wrong if you just press B and controllers really wont be very happy.
I laugh at this to be honest, they just care about my climb. I mean, come on its not like I was close to stalling or anything. <_<
Basically, FL is above the transition level, and Altitude is below transition level...
If you're above, your QNH is set to 1013hpa (or 29.92in), and if you're below, its either set to the regional QNH or Airfield QNH.
Hope this summarises it for you ;)
