Freda - how often do you actually have to plot
shapes from coordinates?
I fly 100-150hrs/year and the bigger part of that is in the UK. The number of instances where I see shapes that need plotting is in low single digits per year. In 2010, not yet.
You mention a model aircraft flying notam. You should not actually read dross like that, never mind plot it. Unless you fly at levels where you will get done for low flying, model planes are irrelevant.
All that matters is stuff that actually affects your flight -
bearing in mind that you are in Class G.
For example a notam saying that some plane will be flying in some area, not in accordance with rules of the air, that is garbage, because in Class G most people fly not IAW the rules of the air
99% of the text of the average NRB is skipped in seconds.
Maybe this is where so many people are going wrong. They actually read all the garbage... kite flying, unlit chimneys, military a/c flying with transponder codes allocated by General Hooton...............
