All,
Which all goes to prove --- Ya gotta cotton to what youse is doing, where ever you are.
About the only thing that is standard is that so many countries do it "their way".
RE; US, the AIM has a very clear statement of the meaning of the phrase "No ATC speed restriction".
Re: US FAR 91.117(d) ONLY the pilot in command has the legal authority to determine what "minimum safe speed" is, there is no "right answer", it is the responsibility of the Pilot in Command and nobody else. See also FAR 91.3.
For what it's worth, in a -400 heavy, I will not operate with flap out for one minute longer than necessary to clean up, on the basis of the O negative G limit, with any flap extended, alone. I can't forecast smooth air, can you.
Tootle pip !!
