Ok I have downloaded the file from Avsim, and no longer having that problem. Thanks. I am starting to like this bird. The flight went pretty good, except for the landing. Is it true I need all 3 autopilot buttons activated to do a full autoland? I had only one activated and near the runway the plane went 'haywire'. I should disconnect the autopilot much earlier and manually land if only 1 autopilot is engaged? Finally how do I know what the Zero Fuel weight is? I was expecting to see it in the ACE configuration editor but I don't see it.

Hello.

Firstly, most Boeing airliners have three autopilot systems - left, center and right. Airbus have only two. In an emergency, airliners can autoland with just one autopilot engaged, though I imagine that most company policies recommend engaging all of the autopilots just incase.

Say you have one autopilot engaged during an autoland and it fails, you will have to disengage the entire autopilot system and take necessary action. However, say you have all three autopilots engaged during an autoland and it fails, the other two working autopilots will still be able to continue.

I have been told that there is an error with the 757-200 autoland in FS9. I've tried autolanding three times and every time I approach the threshold, the aircraft pitches down and lands heavy on it's nose gear first. Hopefully Captain Sim will fix this in the upcoming update. From now on, you will just have to disengage the autopilot before touching down (i.e. fly an ILS approach and manually land).

On an autoland, the aircraft will flare and rollout automatically, but since there's an error, you'll have to disengage the autopilot, flare and rollout manually.

Zero fuel weight can be found by going to the FS9 fuel window. I think you press alt, go to aircraft and click fuel and payload. Then select 0% fuel in all tanks and then you'll have your zero fuel weight.
