Procedure for calculating weight and balance

If you fly a cruise speed of 150
knots in a Baron, you'd still have different elevator positions
depending on CG location. In fact, the position would change during the
flight with fuel burn. Which would be "neutral"?

The one that aligns the trim tabs with the control surfaces.

In this case, you really need to listen to what Thomas and others are
saying. There is no neutral position. There is just a natural
position for a certain flight regime.

The neutral position for trim tabs is the position in which the trim
tabs are aligned with the control surface. The neutral position for
control surfaces is the position in which they are aligned with the
surfaces to which they are attached (wings or stabilizers).

Ok Anthony, you have perfectly loaded your aircraft so the that it trims out
to what you like to call nuetra or default. What are you going to do once
you have burned off fuel and the CG changes?

Careful. Glass houses and all that.


Fire away.





Plus it's fun.


Dude, do more flying. I can think of a lot more fun things, than
constantly bashing one teenage boy on the net :-)

What's the neutral position of a Cub or Cessna 180?

The problem is he isn't a teenager.

Adjust the trim. Ideally, I'd be in an aircraft where the fuel load
is already at that ideal neutral point, and so very little adjustment
would be required.

I don't know. I've never flown anything that tiny.

No such animal.
