Does turning in a plane make water fall out your glass?

I've been in a few arguments about this.





When a big plane like a 747 turns, its pressurized and all that but you dont feel it banking, the only way to know is if you look out your window, you are on your side but gravity seems like its still pulling you towards the floor of the plane instead of in to the side of the plane IE the earth.





Now I was wondering does that mean that if you had a glass of water, and the plane tilted while turning, like all passenger planes do, will the water move with the glass and you, or will it look incredibly weird as the water basically tiltes sideways ignoring the plane.





If anyone doesnt really understand the question I can explain a bit more thuroughly.





Thanks.|||Pilots are trained to do what are called 1 G turns. As the plane is turning the pilot balances the centrifugal force with the angle of the plane. Done correctly you'll never feel a thing.|||I'm a Pilot......I was trained to do a 1G Turn ?????





What are you talking about.....Sounds like you Baffled him with


Bull crap...

PS the forces CHANGE during the turn if there's WIND

|||no because the centre of gravity shifts and holds the water in the glass|||Depending on how hard the plane is banking the water will almost always ignore the planes tilt and be attracted towards earth.|||Yes it does, that's why it's not a good idea to fill your glass to the brim.|||Centrifical force hold the water in the glass provided the pilot turns the plane appropriately.|||Sorry, can't help. Once the plane starts to turn my stress level increases +++ and I switch off from what is happening. I certainly don't think about it.|||Water will not spill fom a glass in a coordinated turn. By that I mean that the turn must be made using , both rudder and aileron to create a smooth banking turn. The reason water would spill in a car that is turning is because a car makes a skidding turn. If you drive th car fast around a banked turn, water would not spill. Aiplane turns are banked and not skids. You could spill water in an airplane if you makde th turn using only rudder or aileron -- that would be a skidding turn. Hope this helps.|||If your Flying "Right" ... Your in what's called a Coordinated Turn....There's an instrument and it's got a "Ball" in liquid....


If the "Yaw" is off in your turn....it will show the "Ball" moving from center.....The rule is "Step on the Ball"





If the Ball was to the right....You would give MORE right Rudder...





If the Ball was to the Left.....More Left Rudder....





Until the Ball stays in the center during the turn...





Then the Water ( and the Fuel in the Tanks ) stays level...





Now if your Just learning to Fly.....Yes, the water could SPILL

Mike %26amp; "Jaz" in MN ( N381PM)|||gravity mantains water in the glass|||pressurization has nothing to do with not feeling the turn, its the pilot flying the aircraft...The guy up front is in a coordinated flight, using rudder and ailerons so the horizontal component of flight is in an equalibrium(think of centrifugal force). In other words, think of when you go around a tight turn in your car, you get pushed to the inside of the turn (a skid). Go around that same turn at a constant rate, and a burm of 30 degrees (just an example, not neccessarily 30, but its just an example!) , you won't feel that centrifical force as much pulling you to the side as much as you would feel it "in the seat of your pants!".





Bob Hoover has a great video demonstrating this. Check out the link:

Its a neat thing! Gotta love science!|||well think of it this way when you get a yoyo and swing it was is the act that keeps it away from the center (centrifical force) so what happens is a plane moving so fast such as the 747 which cruises as mach .85 turns and the centrifical force takes action thus keeping your water in your cup.








Cheers|||yes, it's happened to me and also my fish started walking away
