This flight

Every leg, judged together. The departure is also checked for an immediate return — a problem after rotation puts you back down at close to take-off mass, the heaviest landing of the flight. Pick any row to open that leg on the charts.

Add a destination from the strip at the top of the page, and this becomes the whole trip at a glance.

Result

Compare factoring bases
Worst case 1785 kg · nil wind

A reference, not today's answer: the same chart read at maximum mass with no headwind. Expected to fail sometimes.
