Anyone who uses both have any problems? I have one that I have seen so far and that is when I use the key assigned to fspassengers nav,speed,altitude etc. When I use the key assigned, the input values desired are not vocally sounded and put into the autopilot. Thanks

I love FSPassengers, however I saw warnings on the MD11 about using external payload modifiers (like FSPassengers). I know that doesn't answer your question, however I thought I'd share my concern.Tim Dobrowolsky

I have been using FSP for both FS9 and FSX for years. There is one thing I've learned over the years when it comes to complex aircraft. Disable FSP's ability to modify the payload and fuel. It's just not worth the time and effort. I use FSBuild2 and TOPCAT for that and let my passengers come along for the ride.
