Just resurrecting an old thread here....
I'd like to "compare" the turbulence levels at which some flyers here indicated they were getting motion-sickness.
I know it is different from person to person, but i am interested to find out. Also, is it the same movement sensation regardless of what aircraft?
If I may, I'd like to use the scenario of a glass of water on a typical boeing jet (737, 747 etc) whilst cruising altitude.
Mild turbulence: slight movement of the water in the cup.
Medium turbulence: perhaps slight spillage. cup itself may move intermittently
Strong turbulence: water spillage, cup needs to be held to prevent tipping.
