Useless as is. Needs to be combined with something like <a href="https://www.greatcirclemap.com" rel="nofollow">https://www.greatcirclemap.com</a><p>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.<p>Or just use something made by Jeppesen, Universal Weather and Aviation, Air Routing International, ForeFlight, ...<p>Or use the stuff built into the flight deck of any contemporary Jet not belonging into a museeum :)<p>Or let the pilots handle that, which come with the Jet, anyways, when you charter one.<p>Delegate!
