when I was learning to fly, there was something in the aircraft of all students who had not grasped navigation, it was called an instructor.
Rather a stupid comment. After completing circuit consolidation, students should then fly a number of solo GH trips
before starting navigation training. Unfortunately many of the inferior PPL schools don't seem to include this important element in their courses.
With a GNC250 as the secondary VHF radio, it made sense to keep the GPS element selected to present position from the home aerodrome. Students didn't even have to know how to select anything; all they had to do was just to switch it on and let it inititialise. Before they flew their first solo GH trip, they were checked to ensure they could indeed carry out this simple action.
