what happens when the battery fails or the tablet decides it's not playing, or the electronic system you learned is superseded in 2 years' time?
I will have my map and printed PLOG, I will know exactly where my position is when the battery decides to pack up so will carry on the flight using map, printed PLOG and watch... No big deal.
With the way technology is going in 2 years there will be something making life even easier to move on to - if there isn't and the app store closes forever, I will still have a map, ruler, whizz wheel and pencil.
The reason for learning the stopwatch & compass method during the PPL is the same reason why freeform jazz musicians are well-trained in traditional music first - get the basics right, and then you're well-set to learn other stuff more effectively.
I also agree this is essential, but I don't see why when you know this you can't use a gps as your main form of nav?
Personally I like to do all of my planning even for a local bimble. I wouldn't just jump in on a xc without having drawn a line on a map and thought about it first.
I wish more PPLs would realise that having a licence does not stop you from talking to instructors and asking for extra lessons in anything you may or may not have covered,
This is true I know, however my instructor didn't have skydemon and neither did most of the others... (Although after showing him what it can do he does now).
Best learn how to spell properly before relying on electronic devices to do it for you....
lol.
