When I go XC flying of any reasonable length, I will plan using SD in advance and print out the PLOG at the latest opportunity to get the most accurate weather. I will draw up the VFR chart with route and have it handy in the cockpit.
I also input the route into my Garmin 696 which stays handy in case of ipad failure. Just as a complete belt and braces, I setup the GNS430 with a rough route just in case.
I'm amazed I even have the time to get off the ground with all this programming of electronic wizardry!!!
