OK, last one from me on this one (maybe);
Scenario: you are sitting on a deck offshore North Sea, nose into the wind, wind is 270/60. You lift off in a heavy L2 using 6 on the FLI (collective pitch angle on a scale from 0 to 10, etc etc) to stay in an unstable turbulent hover. You apply 6,5, make the TDP (take off decision point) at 20 feet, get out of the turbulence, and then as you reach 65 kts IAS make an immediate 45 degree bank turn to 090 degrees. (180 degree turn)
You do not touch the collective after setting the 6,5.
The 64 000 dollar question is: what happens??
I can tell you the answer, but I guess you know already, don't you PM. If you do not, you should not be in this business
And to everybody else on this thread: don't over-over-theorize this, it is not that complicated.
