Teaching navigation
We still seem to be teaching nav as it was taught a lifetime ago; map, compass and watch. But the world has changed, controlled airspace is all over the country and the consequences of infringing are serious. As it is, the student will do her PPL nav with map and preprepared plog, gain a licence, then just fly around using skydemon. If skydemon becomes unavailable, have we adequatly trained her for that significant problem?
Would it not be better to teach all cross countries with skydemon, whilst maintaining a plog and following progress on a chart? On most training legs, the moving map could be taken away, such that loss of GPS and reversion to map reading would be a routine thing? It could then be hoped that this practice of running paper backup alongside skydemon would continue after graduation. But as it is, she may discard the map and plog in favour of total reliance on skydemon, with no training on reversion to paper.
