Ever tried to copy an area frequency boundary from an ERC(L) to a WAC? or better still from a little screen?? Your error might be 25 or 30 miles!
Thank goodness for Ozrunways then.
Many VFR pilots I have spoken to have difficulty in working out what the correct frequency is when at 8500 in areas where there are different frequencies allocated above and below 8500.
