Well done! :-) We all make little mistakes at some point or other. I like Jan like your approach to technology.
I saw FlightChops also made a couple of videos where he is clearly too busy thinking about production value / filming than learning in the lesson. Quite interesting to see his reflexion later on about it.
Although this is yet to happen, (thanks to good pre-flight and carrying many spare chargers to recharge the iPad / Garmin Glo if needed) being able to fly by sight / with map is really important when it all goes wrong!
Good luck on our skills test!
