Vmc in ground effect

[Traffic]

Don't lose any sleep over this. This is the same as wondering whether the glass is half full or half empty or whether the house burned up or burned down.

Vmc is a constant in an environment that changes not the other way around.

Ground effect reduces upwash and downwash of the airflow. This cushioning effect produces more lift and lowers the induced drag but this does not necessarily correlate with control speeds.

Vmc like all other critical V numbers are basically IAS dependent.

I always believe that if you are in ground effect you are arriving or about to die so who really cares.
