Good point Bigendbob.
They don't teach you that on your instructors course. Chart origami on 2 mile finals while steering with your knees while you trial flight barfs in the chart.
And if you do it right you only have to wipe it down afterwards and swap it with another one in the lost property box.
Anyone got their hands on one of those 1 : 1 000 000 charts?
What they like?
Wouldn't give them to a student mind but handy for the rest of us. Especially for the IR boys/girls that still want the option of VFR winging it.
