I was doing a flight from KLAS to KDFW today and wound up with pressures at around 30.37mb. At this level of pressure, RC4 thought I was not at the assigned altitude and kept barking at me for busting it. I made sure my pressure gauge was indeed correct (pressing the letter b.), but it didn't seem to register with RC4 properly. This is the first time I've seen pressures this high and the first time RC4 couldn't interpret it. I'm not sure if anyone else has seen this issue, but it basically forced me to shut down RC4 and land manually.

Yes! I had similar.I solved it by using Shift-Ctrl-M to hand over control which seemed to set the pressure as RC wanted it, and Shift-Ctrl-M again to take back control . . . and made sure I didn't press B! I have read that there are times when you shouldn't use B with RC, but I need to read up on why.John

METAR KDFW 061753Z 18008KT 10SM CLR 16/M02 A3037 RMK AO2 SLP282 T01611017 10167 20033 58005is the real world surface pressure (MSL) in inches of mercury, not mb. 30.37 is not out of range for RC and is just above standard pressure. Your altimeter should be set for .in, not .mb, in the US/FAA areas. Some altimeters have a selector that allows you to switch and a few read both references, usually standby altimeters.(As a bit of trivia just a few weeks ago as severe weather pounded the midwest and southeast US some areas experienced record lows near I think 28.1 or similar equivalent to a category three hurricane.)That is a normal range. It looks like you were using real world weather. Standard pressure for flight levels (starts at transition altitude of 18,000 feet) in 29.92 inches or 1013 mb for FAA areas. See the RC manual about transition levels and transition altitudes.In general if RC tells you to go to a flight level your altimeter should be set at 29.92 in Hg or 1013 mb. If you are commanded to an altitude in feet the altimeter reference should be set at local surface pressure. This is stated appropriately by the RC controller.The "B" key in FS is hard coded to a transition altitude of 18,000 feet. This fails in many world areas as they use other assigned transition altitudes according to local procedures.What weather program are you using? Also be sure your FSUIPC is at 3.98 or better for FS9 and 4.60 or better for FSX. FSUIPC reads your altitude and surface pressure back to RC.If you are using Active Sky Enhanced for weather especially in FSX, please read the topic pinned at the top of this forum and searchg for those threads in this forum. Be sure the most recent service pack, released just a couple of weeks ago, is installed.
