Geez, I have sat on the sidelines watching those that want high speed finishes, noted the GFA training directive, and concluded that Darwinian selection will solve the challenge.
Firstly McReady: the damage to competition speed is already done some 50 km/5,000 feet away. One should have been on McReady, rather than finishing, under confident, at 200+KPH from 20 km. In the 1970's I recall calculating on a slide rule that a Blanik kinetic at 136 KNOTS, AMSL, no losses, equated to potential to 45 kts at 500 feet ~ or similar. [That is basic, 1/2 Mv^2 = mgh] Then that same sprog [me] could do a circuit and find somewhere to land that 20 others on the same final glide had not already filled!!! [Thanks Tracey T Narromine 77?] And I Directed competitions [in the l970's] that accepted finishes provided the glider was on the airfield [and that had risks - those in the clubhouse may not have seen them, or validated the finish [not to mention that 50 kts hoping to clear the near fence kills v 5 knots at the far fence]]. Then we had staff out in the 40C, now we have GPS/loggers. I appreciated refamil in JAN 2006 at Temora [tks Ron] where we ducked 20 gliders around the task, BUT the final objective was to be parked: off the far upwind end of a safe runway where no-one else could possibly hit us. Then and only then [in 40C] tow back to tie downs. GFA won't need a low finish procedure, Charles Darwin will have solved the problem. GFA should reinstitute the mandate: either straight in approaches, or a minimum of 500 ft AGL' 100 kts across the clubhouse/finish line/GPS cylinder. From somewhere the professional sprog can land safely.

There is now a GFA/CASA approved low finish procedure (provided you are signed out for it). -- Robert Hart [EMAIL PROTECTED] +61 (0)438 385 533 http://www.hart.wattle.id.au _______________________________________________ Aus-soaring mailing list [email protected] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring No virus found in this incoming message Checked by PC Tools AntiVirus (3.1.0.10 - 9.060.002). http://www.pctools.com/anti-virus/ No virus found in this outgoing message Checked by PC Tools AntiVirus (3.1.0.10 - 9.060.002). http://www.pctools.com/anti-virus/ _______________________________________________ Aus-soaring mailing list [email protected] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
