TEN-4,
Imagine yourself as a Global Express pilot (or other complicated/high cockpit workload a/c)....
I assume, by that you mean a flight where one has to change frequencies at three miles, then again at six miles!!
SATCO Biggin,
I hope I wasn't the reason for the "

". If so, then please feel free to PM me and I'll happily talk things through 'off the record'.
Best wishes,
Big Hilly
