Flight Simulator First Officer can be found right here in the Avsim library. It's freeware, and works with any aircraft.

I don't have either of them, but I do use GSX and Flight Simulator First Officer (freeware), which have somewhat similar functionality as AES and FS2Crew. FSCaptain works wonderfully alongside with those. If necessary, it is very easy to switch on/off the officer's/cabin announcements if they should overlap with those of another application. I typically switch off the passenger boarding sounds from GSX and use those from FS Captain instead, and use GSX pushback rather than FS Captain's. I have set up FS Captain so that it will assign me to a particular gate at my destination, and then select the GSX follow-me car to lead me to it. FS Captain's first officer won't talk you through checklists, but he will set the passenger signs and alert you to set the altimeter when crossing transition altitude, for example (and the transition altitudes are realistic, as far as I have seen). Again, this can be toggled on/off if needed. FS Captain will also generate a despatch sheet (available though the standard FSX kneeboard) with detailed navlog, metar and loadout report. I mostly use default FSX and freeware aircraft, and the estimated fuel burn and arrival times are quite accurate. My apologies if this sounds like a sales talk, but I would rank FS Captain as my top essential addon, together with A2A AccuFeel.

Add another vote for FSCaptain. Doesn't matter whether you fly bush aircraft or heavy iron. You can let it generate random flights or use real-world airline schedules. It also adds a virtual copilot and cabin crew, and you may find yourself dealing with blown tires, birdstrikes or icing. Like a previous poster, I never fly without it anymore.
