That's ~ 35 meters per second!
Humans perceive acceleration. You will experience the same acceleration at terminal velocity that you do on the ground: none.
The main thing you would perceive at terminal velocity is wind. There will not be wind in the cabin, even in these flight conditions.
That's correct and all but the lizard part of my brain would be _far_ more concerned with the sudden change in direction/speed and not super concerned with "at least we're not continuing to fall faster!"
(assuming I wasn't standing by the bathrooms and thus thrown into the ceiling; then who knows what i'd be thinking)
1. The start of the drop. This will feel briefly like freefall.
2. The end of the drop. You recognized the gravity (pun intended) of this.
3. Turbulence. The plane will be experiencing terminal velocity wind. I assume this will shake stuff up a bit more than usual inside the cabin.
Using V = sqrt(2ma/pAC) you'd get:
V = sqrt(2(80000 kg)(9.81 m/s^2)/((1.225 kg/m^3)(210 m^2)(0.03)))
V = 451 m/s
Note this assumes an aerodynamically favorable configuration (e.g. nose pointed down) which is not how planes are typically flown.
