I have noticed that when Otto is flying the plane, the altimeter is not always set correctly (ie: FSMeteo altimeter is 29.87 but Otto sets the altimeter at 29.94). This usually happens during descent and after getting ATIS weather for the arrival airport (but not always). I know it is linked to Otto flying, because I took over the flying and was able to reset the altimeter to the correct value. I am currently using v3.01, but this also happened with v3.00.

Bryan,When you are above your Transition Altitude, you need to set the altimeter to 29.92. When you are at/below it, set it to local (29.92 in/hg "Altimeter" in the US/Canada, 1013 millibars "QNH" everywhere else).When Robin is flying, she should set to 29.92 at TA, or 18,000' as the default. TL, Transition Level, is where "Flight Level" is said instead of feet and the ICAO standard of 29.92/1013 altimeter/QNH set is used.One thing to check is that you don't have TL's set to 0's in the controller page. 3.01 is at 0 when you first use it and you need to set the TL numbers for Departure, Center, and Approach airspace.This is all in the manual, except for the initial TL set in 3.01.

Scott,The behavior that I was describing was not related to transition altitude, as I was well below that (and it was set up properly at 18000'). The thing that I had noticed was that at times during the descent phase Otto would keep the altimeter set incorrectly. In one example, FSMeteo showed the current altimeter was 29.87... then I hit "B" to reset the aircraft altimeter... it changed to 29.87... then a few seconds later Otto would change it back to the earlier value of 29.94. My altimeter was well below 18000' (closer to 10000'). Eventually Otto goes back to the correct value... usually after ATC issues an "altimeter is" message.On my next flight I will try to keep a better sequence of when Otto keeps the wrong value. It may be a day or two until I can do that.Thanks!

Bryan,In that case, you don't need to worry about the altimeter until ATC gives it to you. In the real thing, you'd have no clue what the pressure is unless someone tells you. RC will usually issue altimeter every 100 miles or so, or when you change altitude, or when the pressure changes enough that you are in danger of getting busted for altitude. Pressure changes continuously, and telling you every change would drive you nuts (I know because RC used to do that).Robin is just going by what ATC tells her, and it's working fine.
