747FOCAL
"I spoke with(and I can't reveal who I am or who I am about to talk about) a person that most probably knows 747 flight performance better than anyone. He said that an old 747 on initial
climb will have zero rate of climb at 30,000 ft at 830k. I would assume this airplane was much lighter than that. "
Can you clarify the above? I have not seen a 747-2 carry that much air speed, or do you mean 830K for the weight? Again, a bit heavy don’t you think. They were only going to HKG. Better go back to your 747 contact and
get him to explain.
Awaiting.
