I have uploaded a PFPX file for the Premier 1A I have created, with data obtained from the POH. You can download it from Aerosoft's PFPX suport forum: http://forum.aerosoft.com/index.php?/files/file/4693-beech-390-premier-1a/ Feel free to try it out and report any issues here. Enjoy! David

There seems to be some confusion at Carenado about airspeed and Mach limits and the way they should be displayed. Many times I have gotten the dreaded overspeed siren only to look at the airspeed display and see my airspeed needle nowhere near the "barber pole" limit. Those limits, for purposes of the FSX/P3D aural warnings and "Overspeed" message, are contained in the aircraft.cfg file in the [Reference Speeds] section. Sometimes they are accurate and sometimes they are not. But either way, they are the limits the simulator uses internally. The problem arises in Carenado's gauge configuration files where those limits are seldom (read never) in agreement with those in the aircraft.cfg file. This is a brief tutorial on how to correct this error and have the airspeed indicator match the actual limits. I will use the Premier IA as the example. Tools required 1. A good Aviation Calculator. I like this one..... http://www.hochwarth.com/misc/AviationCalculator.html 2. The actual limits. For the Premier 1A, Ray has scrounged some good information for us.... Step 1. From Ray's data the limits on the Premier are Vmo = 320 and Mmo = 0.80. Note that these numbers aren't accurately reflected in the aircraft.cfg file. (max_indicated_speed=335 max_mach=0.82). Simply open the aircraft.cfg file and change them. Absent these numbers or if Carenado didn't produce them in their documentation, just use what's in the aircraft.cfg file. In the next step we will see how to get the proper crossover altitude with only the airspeed and Mach limit numbers. Step 2. Notice that in Ray's table the "crossover altitude" is actually given (in most of their airplanes it is not). Let's use the calculator to check it (or to find it if we don't have it). Open the Aviation Calculator from the link in another window. In the "Crossover Altitude" section enter 320 KCAS and 0.80 Mach. Press "Compute." The answer you should get is 27582 feet. From Ray's data this appears to be accurate (27,600 ft.). Step 3. Next, extract the cab file "CARPROLINE21_390IA.cab" into a new folder of the same name (minus the ".cab") and place it in your panel folder. Using "spb2xml.exe" make an .xml copy of the file "Proline_Config_390.spb" and put it in the same folder. (the freeware "spb2xml.exe" can easily be found on the internet). You should now have a file named "Proline_Config_390.xml" in the CARPROLINE21_390IA" folder. Step 4. Open "Proline_Config_390.xml" with notepad. Scroll down to the line that says..... 33730 (>L:Barber_Pole_Altitude) //Limit to use vne or barber pole max speed 337 (>L:Vne, knots) //Never exceed speed 328 (>L:Vno, knots) //Maximum structural cruising speed Change these lines to read... 27582 (>L:Barber_Pole_Altitude) //Limit to use vne or barber pole max speed 320 (>L:Vne, knots) //Never exceed speed 320 (>L:Vno, knots) //Maximum structural cruising speed ......and save the file. Step 5. Rename the file "Proline_Config_390_1.xml" and delete all other files in the folder. Step 6. Open the panel.cfg file and everywhere you see "Proline_Config_390" replace it with "Proline_Config_390_1". Save the panel.cfg file and run the simulator. You should find that the PL21 Barber Pole now matches the actual airplane limitations. Even though the Premier in v4 doesn't seem to have the blaring warning horn, you should see an accurate "Overspeed" warning on your screen should you have that option turned on.
