I could tell you the LMT at Broken Hill, New South Wales whist on the other side of the world and plot to within a cocked-hat of 2NM - neither of which might seem particularly relevant today but it was once. I am often surprised at how little some of the more recently trained guys and girls understand about how navigation really works or how to 'read' the weather (I don't mean TAF's and METARS). Morse is another example.
Quite why I should relish having to take time off work, spend loads of money and mental effort to prove my passion, when I can jump in something with an N on the back, earn decent money and do what I love doing isn't what I see as learning all there is to know about it. I'd rather be doing it, not grounding myself to pass some nonsense exams.
Why are you then?
