Indeed, though the way I read that FCTM excerpt is that it considers that 5-600' is EARLY.
It seems to be a bit of legalistic stuff to avoid MINIMUMS *click click* oh sh*t crunch rather than genuine advice on how to fly the aircraft. One or two of my colleagues have much earlier revisions of the FCTM which contain a lot more sensible stuff that seems to have been excised by the lawyers.
