According to the Mavic Manual, flights in P-mode in "polar areas" are not possible (page 50). I was flying in northern Finland and experienced quite frequent drops from GPS to Atti mode in mid flight, and GPS was not recovered for 1-2 minutes - quite scary. Analysing the log files, I noticed GPS health problems, while there were still many satellites registered. Is this a consequence of this restriction? Anybody else had similar experiences? Can "polar areas" be defined more clearly, i.e. by latitude?
