**drwls**, Sunday, June 2, 2013 at 1:21amPlane mass increases by a factor of 2^3 = 8.

Plane lift increases by a factor 2^2 = 4

Plane drag increases by an unknown factor between 1 and 2. Engine power will have to increase to compenstate for increased prssure drag and boundary layer friction.

The plane's velocity will have to increase by v1/v0 = sqrt2 so that the new lift (4*2 times higher than before) will match the increased weight (8x higher).
