Notes:It was over Montargis France LFEM at FL050 the windsock showed something like 230°/20 kts gusting 25.
Initially I wondered if I would fly or not and finally took the decision to make a short local flight, when I was at 3000' I managed to go VFR over the ceiling to FL050 not above because of a Class A airspace.
I decided to switch on my GPS to check the GS and while heading 090° my GS was 166 kts (and more probably!).
