Best place for CG along roll axis

There has got to be a MSFS usegroup that you can ask these questions on.
Not all MSFS aircraft react the same as a real airplane

and most any real airplane will drop the nose without aft stick pressure
when rolled into a turn.

After constantly struggling with a heavy nose in several aircraft it
occurred to me that having a fat pilot in front and nothing else was
moving the CG forward. I put some weight in back and moved the CG
further back over the wings, and handling improved greatly. Is there
a way (other than consulting a manual each time) to determine exactly
where over the wing is the best place for the CG? MSFS is kind enough
to show me a diagram with the current CG marked, but I don't know how
far back I should try to place it.

NO. Pilots must calculate weight and balance prior to each flight.

And they all do this methodically?

I'm not sure what you mean by methodically.

There is a specific method used to calculate W&B, so they should be using
the prescribed method.

If you mean do they always do this, I can only speak for myself. I have a
pre-calculated one for myself with full fuel, myself with fuel to tabs
(partial tanks) and myself and a 170lb person in the front right seat, both
with full fuel and tabs. Anything else I need to recalculate.

Mxsmanic,

Those that you don't find in your mile-high piles of accident reports,
yes.

The best place for the CG along the ROLL axis is somewhere near the middle.
Moving weight from front to back won't make a difference in this case.

In real life, you do have to consult the manual and do the math if you are
flying with a load you haven't already calculated to get the CG in range
from front to back.

Also, in real life there is a difference between having the CG too far
forward and not using the trim properly.

Does MSFS let you set the weight of the pilot? That's kinda neat. I wish I
could do the same in real life!


The FAA says I weight 170 lbs. Who am I to argue?

I think I remember when I weighed 170lbs. I was in 7th grade.

One thing I wonder is this: If I'm alone in the aircraft, in the left
seat at the front, can I put an counterbalancing weight in the rear
seat on the right, or would putting weight in a diagonally opposed
position make the aircraft unstable? If it works, it would be easier
to balance things; I could throw some sandbags in the right rear
corner of the aircraft to balance my weight.

It's not unheard of for a pilot to counterbalance weight in the plane if
necessary, especially in some models that are noseheavy, let's say because of
a three-blade prop. CG refers to forward/aft. I don't believe that weight &
balance for left & right side of a plane is of major concern, even on the big
planes...

This is all basic flight training stuff. I would recommend the book
"Stick and Rudder" as a good starting place.

I looked for it at the pilot's store Thursday, but I couldn't find it.
It's hard to find English specialty books here.

You can probably find it on EBay or half.com...

Mxsmanic, ask these questions over there. I guarantee you'll get the answers
you're looking for over there.

Using the roll axis to define CG location is not the classical way it
is done, however when weight is added up front or in back, it does move
the CG along the roll axis, since the axis about which the aircraft
rolls runs generally from nose to tail. The classic way is to state the
CG is at a location along the MAC (mean aerodynamic chord), usually
stated as percent of MAC.

So if someone tosses a bag in the back, or if the person next to you
weighs more or less than 170 lbs, you redo the calculations?

I don't recall mentioning turns.
