I do not have anything more to contribute to this thread now the experts have explained how peformance data, etc, ad nausium, affect a departure., except!
The POINT of this thread was that the crew of the aircraft in question did all the fancy math for the flight, loaded fuel, passengers in the back, baggage, freight, food, flight plan, and the other complicated stuff.
Then they pushed back and started the engines......
Then asked "Any tall ships?"
Then they stopped and shut down and re-did all the fancy math.
The tall ships question should have come before the loading pax, freight, fuel, etc.
That is MY point.
