Guys
I was flying to Samedan today, and was able to catch up METAR over Germany. Thay stated OVC090. As I know, they will let me descend to FL170 as IFR so I assumed, that clouds are somewhere in FL150. I even didnt tried to go there and asked for alternate (st gallen).
But what the hell. When I have descended, I have realized, that there is flat overcast over all the Alps in FL150. Just to cancel IFR and fly there, but I didnt wanted to change my decision.
So my question is.
- Over Samedan, they let you descend to FL170 as a IFR
- Tha altitude of highest peaks around Engadine valley is JUST 12.000 ft
- Do you have some non certified GPS procedure, some set of waypoints and altitudes, that will guide you safelly from FL170, lets say to FL100 in the middle of a walley?
