Fr8Dog:
Despite what some (Desert185) have claimed here, there is a large increase in pitch-up from the thrust of the engines.
In relative terms, compared to the pitch-up realized in a DC-8, the 747 by comparison has minimal pitch up/down when the thrust levers are moved. I was speaking in comparative terms, and would not characterize the 747 having "a large increase in pitch-up from the thrust of the engines" by comparison.
I am only speaking from my experiences in having flown different aircraft (and still flying both the DC-8 and 747 concurrently, BTW, making the comparison all the more obvious, at least to me). Your perception may differ, as everyone seems to see things differently, which is certainly verified by this thread.
