Show HN: Calculate Your Private Jet's Carbon Footprint

Also winds/jet stream at actual flight level at the time flown, and finally the price of Jet-A(1)/B at the involved FBOs.

Or use the stuff built into the flight deck of any contemporary Jet not belonging into a museeum :)

Or let the pilots handle that, which come with the Jet, anyways, when you charter one.

Delegate!

Or at least in my case it is.
