Thanks much so far,
the problem I encounter when flying a somewhat underpowered turboprop is flying into the wake of a medium size aircraft which climbs quickly. The vortex then sinks and we end up in it. Highly uncomfortable.
Don't want to upset folks in the tower but don't want to have the aircraft taking a course of it's own either. A dilemma I guess.
Thanks for the link, at least I now have an official procedure to consult, because the rules seem to differ from the one's used on this side of the channel.
Happy landings (or take-offs for that matter)
