Hello,

 

i have a huge takeoff Problem with the 737 NGX.

 

If i leave all values in CDU --> FSActions --> FUEL unchanged and only enter the ZFM and CG% with double LSK click on the CDU --> Performance page the plane takes off normally.

 

However as soon as I change the Standard fuel amount of 21000 KGs to lets say 20500 the plane takes off at 110 knots before V1 is announced.

 

This problem happens with or without correct trim setting.

 

Hope you guys can help me !

 

Regards Andi

Are you using the NGX FMC or FSX menu for refueling?

I use the NGX FMC menu.

Try to load the default state of the aircraft on a runway, without changing anything just add 5 flaps and takeoff. See if it happens...

After 2 hours of trying i found the Problem. My Saitek Yoke is sometimes pulling up from alone even though calibrated correctly. I think i Need to get a new one. Thx anyway !
