Clearways is now the only site where cadets are housed when out in NZ.
The Hamilton traffic situation was nightmarish about 5 months ago with aircraft who were in the VFR circuit routinely being told to land because there were so many aircraft outside the zone waiting to come in and traffic needing to depart. Not to mention the scheduled movements when the training aircraft would stop and literally back up to the fuel pump while this traffic landed/departed.
The NZWK operation has been canned in terms of operating there as a second base however it is routine for cadets to be sent there in the first month or so of training in order to get their first few solo flights complete in a 'quieter' environment. These lesses are all circuits and cause the circuit traffic is so quiet at WK compared to HN that this seems to happen with most courses now.
