What would be the effect of a thin layer of ice on a parachute canopy?
There are no aerodynamics other than pure drag. This does not even consider
that the trip down is going to be pretty quick anyway. Also the constant
flexing of the canopy is going to shed any layers that amounted to anything,
just like deicing boots. I'll wave to you on my way down!

I don't know that there would be any aerodynamic impact, I was thinking
more of weight. I've never seen a round canopy up close and personal.
Are you sure they flex all that much? I can around the periphery where
the cords attach and the air is spilling out, but I suspect that the
middle half or more of the canopy is pretty rigid once filled with air
and stable.
