Boeing 727's didn't have advanced fmc's that tell the pilots what T/O trim is. Unless told otherwise in the loadsheets pilots normally use 5 units of trim.

Best Regards,
Robert ;)

We used performance charts from the Boeing manual to derive a stab trim setting.

The CS 727 is a game and should be flown as one. There is no way to balance payload. There is no way to determine takeoff EPR, V speeds, minimum flap manouvering speeds, climb EPR, outside air temperature. Those performance charts were not supplied. If you can get a hold of a Take Off Landing Data Card and some performance charts you could operate it more realisticly. Until then it's jsut a fancy default plane.

Until we wait for Captain Sim's solution you may try this :

Open the following file:

...\Microsoft Games\Microsoft Flight Simulator X\SimObjects\Airplanes\CS_B727-100\AIRCRAFT.CFG

find the following line:

elevator_trim_effectiveness = 1.0

change to :

elevator_trim_effectiveness = 0.3

JETPILOT, you'v been very helpfull in this forum. Thank you for all your posts.

Captain Mucura.

Thanks Captain....

I just tried it and it didn't affect anything for me. The trim is operting at the same rate. Did it work for you?

When your flying an approach you can't be looking down at your trim wheel. That's a band aid for a problem that should be addressed by CS.

I use the trim wheel on my go flight module to adjust trim. I do not look down and check position, with the exception of take off, where I set it at 4.5. On climb, cruise or approach I adjust the trim wheel to take my feedback stick to a position where it is not fully pulled back, or pushed forward. I have found like the real plane you will constantly be adjusting �the trim, as it burns fuel or gains/reduces alitude. I have a DVD's of the plane flying with Cougar Airlines, and the pilot is adjusting the electrical trim constantly, until the plane is set on autopilot.
