Your TAS at 10,000 is 144 KTS VS the snail like 125 KTS Calculated VNE on the gauge .
The interesting thing about VNE in "level flight":
1/ at sea level there is not enough power to get to 152kts; at 10,000 ft there is not enough power to get to 125kts.
2/ at 10,000ft the vibration level that you get, the colective position, they all come in a way that 125kts feels like 152kts.
unless you are thick and only look at the indicated speed, its not such a pitfall.
