What is the Impact of Ground Velocity on Airplane Passengers?

[anneku]

Homework Statement

Should a passenger in an airplane be more concerned about the airplane's air velocity or its ground velocity?

Relevant Equations

relative velocity in two dimensions

Answer is ground velocity but I thought it should be air velocity as that will influence the turbulence and direction no?

 

[Orodruin]

Define ”concerned about”. As a passenger I would certainly be concerned if the air velocity was not sufficient to maintain the lift. However, for the purpose of reaching the destination, ground velocity is clearly what is relevant.
