Sfgiants13

It probably isn't but I thought I'd ask anyway. When I fly, I use unlimited FPS near the airports to help with smoothness and fluidity. Once I start climbing out until I get close to landing, I lock the FPS to help with the texture loading since it is still smooth enough once I"m away from the airports. Is it possible to use FSUIPC to program a key that will switch my P3D settings from locked to unlimited FPS?

This may be a dumb question but I couldn't find the info in the manual. When programming the FMS, the radio screen is set to "FMS auto" for both NAV1 and NAV2 unless I manually put in a frequency. 1) What specifically does FMS auto mean? Even if I plug in a frequency manually, when I use VNAV/LNAV it still runs off of the FMS. Does it just mean it's going to show and autotune the closest VOR freq on my route? 2) Once I do put in a frequency manually, how do I get that NAV radio to go back to FMS auto (even though I'm not sure what exactly it means)? 3) How do I pull up the NAV2 radio on the PFD? Thanks
