Cessna, doesn't it make you feel kind of weird having someone else calculate the #s for you? Does the Pilot IC do a double-check on what the actual calculations were to make sure it makes sense? I mean, wasn't it something like this that caused the Gimli Glider incident in the 80s in Canada? for those of you who don't know, the Gimli Glider was a B767 that took 22,000 units of fuel for a flight, and it turned out that the pilots were using the new metric system at the time but the groud crews put in 22,000 lbs instead, which is significantly less... not sure if my #s are right but you get the gist... the pilots thought they had the right amount of fuel on board, and not halfway through their trip got low-pressure indications, ran out of fuel and had to glide into originally winnipeg, but when they realized they weren't going to make it, landed on a small abandonned airfield (that happened to be used by go-kart racers that day... of course the plane coming in on a wing and a prayer didn't make that much noise either so it was only at the last minute that people saw the airliner gliding in and scrambled out of the way for it to make a landing... there's a pretty terrible made for tv movie out there somewhere about it as well... maybe someone knows the title?
