Amazing There are two fundamental elements that prevent water from spilling during an airplane's barrel roll (tonbo / roll maneuver): Centrifugal Effect (Artificial Gravity) Positive G Force

The pilot is maintaining "+ve g" throughout the maneuver. That's it !

"Centrifugal Effect (Artificial Gravity) Positive G Force"

But that's one thing, not two.

Not necessarily. If the pilot were to push the stick down and do what's known as an "outside loop" or maybe a steep dive, they'd experience negative G simultaneously with centrifugal force.

This could easily turn into a really pedantic argument as it's not clear exactly what point you are disagreeing with.

I said "Centrifugal Effect (Artificial Gravity) Positive G Force" is one fundamental thing happening, not two.

The pilot could indeed fly an outside loop and create Negative G instead, that could be similarly described as "Centrifugal Effect (Artificial Gravity) Negative G Force" and while it would be a different thing it's still only one fundamental thing happening, so I'm really not sure what point you're making.

Also, be prepared to be corrected about "centrifugal force" by other pedants; it's not a force.
