So I hooked up my roommates Saitek Pro Flight Yoke, throttles, and pedals to my computer, mapped it all out, was going to do a short hop from KVRB to KMCO in the Challenger 300, pick up some "pax" and fuel, then blast off to N'awleans, but Xplane had different ideas. Had AirTrack set up to vector me for the ILS 36R at KMCO, taxied out, liftoff was no problem, positive rate - gear up, 1,000ft L ENGINE FIRE! Bells, whistles, warning lights and the ECS lit up like a Christmas tree. Its really funny how real world training kicked in. I immediately retarded the left throttle to idle, flipped the "RUN" switch to "OFF" continued down and activated the fire bottle for the left engine, and increased the thrust on the right one. I then preceded to keep flying the plane, and started a left turn to come back around to land. Mentally, I called my mayday and also tuned 7700 in my transponder. Flew a nice, high downwind and lined her up for the single engine landing. It wasn't my prettiest approach, but we made it back down safely. After I taxied off the runway, XP gave me a left side hydraulic failure too, so I had to turn the pumps on to taxi back to the ramp. I had turned on the "Mean time between failures" option on and set it to 2,000 hours. Totally random, but XP simulated a bird strike (hence the engine fire, probably a compressor stall) and gave me a "real world" scenario to deal with. Coupled with my real-world training, albeit not in anything as complex as this, the experience actually made me sweat a bit and was a hell of a lot more fun than any straight-line flight I've done before. That, was definitely cool!
