Procedure for calculating weight and balance

Unless you are familiar with every aircraft ever built, you don't
really know.

For a plane to have the fuel loaded as you suggest the fuel would have to be
contained in an infinitely narrow (forward to aft)tank and be moveable to
take into account what the pilot had for breakfast that morning.

Look at the control surface. If the trim tab is flush with the
control surface, it is in its neutral position.

There is no trim tab - it's a spring type system to balance out the
force on the column. So the question remains, what is the neutral
position?

Trim tabs that don't exist don't have neutral positions.

Hey don't be a ******. What is the neutral position for a spring type
trim control? You've claimed there is one, and I wanna know where it is
and how you can tell.

I said tab, not control. A tab is neutral when it is flush with the
control surface to which it is attached.

I don't think *you* asked the question - *I* did. Shall I quote it for
you?

Thanks! I've located and downloaded both. They should be very
helpful, particularly the latter.

Y'All,
Not exactly on topic but something to try in a simulator and again in an
air. Trim for level at cruise,
Put your hands and arms a far forward as you can and hold them there. The
nose of the aircraft will drop and the speed increase slightly in the
airplane but not in the simulator. Then put your hands up and back as far
as you can reach. The plane's nose will rise and airspeed will drop as you
lelnter a climb. You can actually fly the aircraft just be moving your arms
and using the rudder. This is NOT possible on the simulator.

During WWII (See my web site at www.whittsflying.com ) I was the mechanic
operator of a radar bombing
simulator on Tinian Island that provided simulated flights over Japan and
specifically Fukuoka. We worked on the attack only to find on the Sept 9,
1945 mission day that the target was obscured by smoke.

Nagasaki.was a secondary target requiring an attack from a direction
opposite to the one practiced. Thus this very first electronic simulator
paved the way for the failures of future electronic simulators to really
provide a true sense of what is supposed to happen.

Another Comparison:
I had a Designated Examiner that I had tutored through his CFI come to me in
need of a Flight Review.
I told him as, we got into the airplane, that we were going to make an IFR
flight from Concord to shoot the ILS in Oakland. We discussed the flight
and requirements except for one minor aspect which began on takeoff.

As he lined up on the runway, I informed him that I had electrified the
yoke. Were he to touch the yoke he would go up in smoke. Under the hood he
flew a perfect flight without touching the yoke including making
the Oakland published missed at which point I asked his permission to have a
go at it. It can be done in an airplane. Can anyone do it in a simulator?
Has it even been tried?
