+xAnd the MAYDAY cry reminds us of what ? . . . Skydemon is a navigational aid for convenience !
If you cannot go flying because Skydemon does not work, you may consider seriously quit flying.

Okay, so serious SemperFi! It was a light, little hearted joke. Just for the record, I only really use Skydemon as a planning tool, and it's a back up if I get really stuck to save infringing. I turn the screen off and fly bearings, timings and ground features - the old fashion way.
