In my limited experience the straight in finish, with a finish circle 2-3km, is the safest and least complicated solution for finishes.
Otherwise anything that reduces gaggles is a good thing IMHO. Although, end of the day respect the current pilots at comps right to set the rules for their comp........on the basis they don't increase the accident rate and therefore insurance premiums :-) Best Regards, Mike > On 13 Feb 2014, at 7:41 pm, Peter Champness <[email protected]> wrote: > > Excellent thoughts Harry. > > I am a very indifferent competition pilot but I have been in a few comps. > > My appreciation is that the worst danger in the comps I have been in involve > gaggles before the start.
