What exactly happens when the trim is adjusted to point the
nose upward?


What type of plane is this for? I have a Mooney and also fly
a 182. Both trim system are very, very different.


For sake of those of us who only own MSFS, let's say a C172.


Does MSFS emulate the servo tab on the elevator? What does it
do when you change the trim in the air?


Trying to emulate real life trim on a simulation system that
uses spring centered control sticks isn't going to work like
real life as you may already know.


Should I post the spoiler on how a couple other mechanisims
work (besides servo tabs)?


I'll raise you one to make three additional trim systems. Any
more?


I can think of four for a total of five, depending on whether
you'd consider hydraulic centering to be the same as a bungee trim
system. theothersa re of course, a tab system which is th emost
common light aircraft system. the trimmable stab, a'la Cub and
most airliners and the vane, like some early T-carts had..
There're probably some others, but i can't think of any.


I'd count that as the same -the acutuating system doesn't count,
just the aerodynamic priciples. So, if you have four I'll raise you
again one to make five... Any raise on five basic methods?


Yeah, they;re essentially the same.

Go on. I'll call.


Should'nt we wait to see if there's any other raise?

Cheers


Would a 100% computer controlled system like the B2 count as yet another
way? Do they even have to trim it or does the computer automatically
adjust for whatever flight regime they set?
