Wake Vortex in USA
Serious question - no "if you don't like **** off home, you will not be missed" answers.
I'm obviously not understanding the USA understanding of wake vortex.
UK recommendations (which are in print) suggest two minutes delay when departing behind a larger aircraft from the same departure point (three minutes from an intersection).
I've never managed to find any recommendations in the FAA publications.
However, on the two recent occassions that I've heard a student be given a take-off clearance immediately after a jet has departed the same point - and said student has declined, citing the desire for (incorrectly) three minutes of seperation for vortex, the controllers have come back and said "You are departing from the same point"- in such a way that they appear to feel that there is NO vortex problem.................yet, on both occassions, a light aircraft on final approach to the same runway for a touch and go was warned about possible vortex problem - despite that aircraft being further away from the vortices.
How can a departing aircraft not be prone to a problem - but a touch and go can??
Also had a warning - some years ago - "Caution wake vortex from the preceding King Air".....but we were both on the taxiway.
