Just returned from 2 weeks in New Zealand and took the opportunity to hire an instructor and a Tecnam Golf (now that's my idea of a microlight, full tanks, two large bodies,bubble canopy, joystick and a 110kt cruise but not allowed in the UK courtesy of BCAR-S). I flew from Wanaka where there is no Tower but everybody gives Downwind and Final calls on the aerodrome frequency. While I was circuit bashing I was in with a Cresco lobbing out tandem skydivers,a Robinson R44, 2 Cessna sight-seeing Cessnas that were very busy and best of all a newly -arrived L-39 jet which was giving pleasure flights at £700 for 20 minutes. Admittedly the viz was good but it was all very safe and is apparently the norm in NZ. Any lessons to be learnt for the UK?
