Met I use the most out of all the subjects.
And its funny the things you use with expecting to.
One person i know was ferrying a plane trans atlantic when the GPS went down. Had to get out the old plotting board and chart and using NDB cross hatches work out the position. You never know when its going to come in useful.
Anyway its a very good way of cutting down the numbers going for CPL/IR if we didn't have it there would be 100,000s of unemployed pilots instead of 1000's
