FS2004: Take Offs With A Mind Of Their Own!

Tue Aug 24, 2004 12:48 am

Hi all,

I have just downloaded an A330-200 in MEA (Middle East Airlines) colours, I was doing a mini test flight around Seattle.. as I was on my take-off roll the plane lifted itself off the runway and climbed!

I didnt have the Auto-Throttle nor the Auto Pilot activated!

Why did this happen?

Well...it happens for me when on low fuel and lots of flap...especially my AirbusNG planes.

Thanks for your reply...

At the moment (as I am fairly new to FS) I fly with unlimited fuel, and my flaps were down at 5, which is normal for a take off roll.

And the same thing has just happened on a Britannia 757-200!!

There must be something within the files of certain downloaded aircraft that make them do this... I'd much rather do the lifting off the runway myself, as it takes some of the fun out of proceedings if its done for you!

It's normal with flight sim, the wings generate lift and as you thunder down the runway the lift is getting greater, all that's happening is that you are thundering down past T/O speed and the aircraft will pitch itself up, on the POSKY A332 (Full with Flaps 10) VR should be 155/165 knots KIAS, go too far past that and it will climb itself.

Same thing happens with the default cessnas too.

Check your trim.

Even in real life a Cessna will pull up its self. With Flaps and it matters how much trim.

Yep, Jim is most likely right. Check the trim. Make sure the elevators are level and not up, because if your trim is set incorrectly with the elevators up, it will lift off as soon as it's possible on it's own.

Last night I took my Canadian North 732 for a spin around YXY for something to do, and apparently my alerons were stuck in a position that to hold the wings level meant having the stick about 3/4 of the way to the far left (in other words all the way left to make a small left turn or about centre to make a small right turn). I didn't notice it till liftoff when the bugger just about put a wing into the ground, but I did manage to (with some difficulty) slowly and carefully turn it around fly out a little bit turn around again and somehow lined it up with the runway (atleast to the point where I could slam it down and use the nosewheel a little to put it on the centerline). I did do a replay and discovered they were in that position during taxi n all aswel..... Anyone ever had that?

CanadianNorth Yes. It happens when you have stacks of fuel in your right tank and none in your left.

It happened to me on a 737 in FS98 a few years back. I figured it was the speed and flaps in combination. However, no such luck with the 744 in FS9, I have occasions wher I struggle to take off in time (no crashes as of yet so I am fortunate in that way).

It happens to me occasionally, you should check the trim and make sure you lift off at VR rather than going too fast on the runway. Certainly a lot of flaps down will make a difference.
