Weight and balance, ballast, trim when flying alone

I've seen pictures of selectors with a "both" position, although apparently
they don't come that way from the factory. Odd that such a position isn't
standard. Dreamfleet puts such a selector in its Bonanza (one of the very few
departures from reality) because MSFS supposedly exaggerates fuel imbalances.
I always leave it in that position.


Please point me to such a picture. I've never seen one.

I want you to do an easy experiment that will show you the problem with
a non gravity feed system that uses a "both" position.

Take a glass of water and two drinking straws. Put one of the straws in
the water and hold the other out side of the glass. Now put both straws
in your mouth and suck. Unless you are doing something to block the
straw that isn't in the water you will find it very hard to get a drink.
The same thing happens with a non gravity feed fuel system in the "both"
mode.

Xactly. I know of an RV6 where they installed a selector with a both"
position "in the interest of safety" How it got past the DAR I have no
idea, but it crashed on it's second flight........

Add a fuel pump.

You sucking provides the analog to the fuel pump.

Where would you place the fuel pump to deal with the problem?

That would depend on the aircraft. I don't know where it is placed in a
Bonanza.

Where it is in the Bo doesn't matter because it doesn't draw from both
tanks at once.

Where would you place a fuel pump in a low wing plane with a tank in
each wing that would not suck air from the empty tank?

In a common sump that is lower than either tank.
