I am New to the site and leaning a lot. Thanks to all that contribute. this is great source of information and learning at lot about my P3 Pro here are my newb questions: Lets assume I take off in P mode and during the flight I get a compass error message during the flight ...Should I manually switch to atti mode and regain control and land ? I believe it will it automatically switch to P atti mode while still in P mode but will P atti allow me to control manually, is not switching to atti the correct procedure? also Is there a message that comes up if the GPS signal is lost? (probably unlikely I know ) but what would be the procedures ? Many Thanks !!
