NZHN is the only airport in the country that has a booking system for day VFR circuits. I wonder why that is if it's not bulging at the seams?
The booking system is only available to two operators. How can anyone else book to avoid getting bumped? Planning ahead doesn't come into it.
By locals I was referring to the local aviation community. Living nearby has nothing to do with my comment.
I also know the aviators at NZWK were pretty happy the CTC satellite operation there was canned. They didn't want NZWK to be another NZHN.
As for believing or not believing all that I hear. I do fly into NZHN from time to time so have seen and heard things first hand and have had my observations confirmed by others that operate there every day.
