Sorry for the delay, didn't see this! The answer is technically yes...I don't have access to the files currently, although I haven't been able to stay on top of maintaining it anyway. It would be something I need to add in code. It had been on the list of potential future updates, but for doing dropoff/pickup type practice, I think Arma didn't care about crew weight in the past. If I can get it updated ever I'll try to add a setting to crew-up. Thanks for the feedback!

You're welcome, no stress and thanks for writing back.
You're probably correct in that at one point in time, added crew didnt affect flight characteristics at all, though I believe with the release of the Helicopter DLC came the optional Advanced Flight Model which can lead to significant changes in the heli responsiveness when flying with full load of passengers in comparison to just the pilot aboard, when the options enabled ( its most apparent on light choppers ) though unsure if this holds true for standard flight model.
Anyway know your missions very useful as is, having spent many thousands of lives practicing (death counter is a nice touch) and thoroughly enjoyed playing, which I still do... thanks for taking the time to make and upload it.
