hi guys,
just my little opinion on it all.
when i first started my nav's, i was taught ten mile markers. yes they worked fine, but then i learnt the 6 minute markers. as an initial learning stage, by comparison, the 6 minute markers were far easier to learn, and were also easier to figure everything out when you're actually en route. figuring out the 1:60 with the 6 minute markers, i dont see being a problem, because you need to know not only how far along course and off course you are, but when you try to get yourself back on course with the details, you also need to know how long you have been travelling off course, so that you can alter your headings per time travelled, etc.
ten mile markers are great for working out distance, fine, but, for any work done en route, ease is the key, so that you're able to continuing navigating....which is what you're there to do in the first place. the time aspect, i believe, is far easier to work it all out not only quickly, but also efficiently. distances are easy to read from a ruler...time...you have to get out the calc wheel and still work out the distances.... i figure you may as well take the fastest way to work it out, so you can keep aviating.
i know now, after having learning the navigation.....exactly which way i will teach it. obviously my students will know both ways, but i will focus the majority of time in training these students, using the way, which will work quickly and easily for them.
sorry its so long
