Hi all,
Recently I bought a Flytec 6030 and I now have a new toy to play with
In order to make the Speed-To-Fly function and all other air-speed dependent functions workable, I entered the Wills Wing U2 polar data as it is published here:
willswing site at page polar-data-for-wills-wing-hang-gliders
(sorry I am not allowed to post HTTP links)
Namely,
V1: 175fpm@23mph
V2: 530fpm@44mph
as it appears in the right-side of the graph.
However, after several flights I noticed that:
1) the Indicated Air Speed is reported too low
2) the Netto Vario is increasing as the Indicated Air Speed decreases
After looking more carefully on the graphs published by Wills Wing, it appears that Vms is at 25mph although on the side it appears as 23mph.
Also in the WW U2 User Manual it is written that the Stall Speed at Maximum Wing Load is at 25mph.
My hook-in-weight is ~180 lbs, which is what WW state they have used to generate their polar graphs.
When I am flying at trim speed the Indicated Air Speed reported by my Flytec 6030 is 23 mph.
Anyone tried to calibrate this instrument for the U2?
Please advise,
Adrian.
