Aren't these maneuvers done such that the local acceleration for all the passengers remains pointing straight toward the bottom of the plane, so that if they close their eyes they don't feel like they are tipping at all? Why can't this continue to work for BWB?
I also don't really understand the turbulence issue. Do planes typically roll during turbulence? My experience has been mostly vertical vibrations.
- ithkuil 7y agoThat's once you set the bank angle and are turning. But in order to initiate the bank you need to apply a torque (via ailerons). If you sit at distance d from the axis you'll experience an acceleration due to this torque changing the angular velocity (four times per turb: once when the banking is initiated and the second time in the opposite direction when the desired bank angle is reached; then the same thing reversed when existing from the turn). An increased distance d exacerbates the effect (think of a lever).
