Agra. Surely you agree that our half wound back system makes VFR flying more complicated.
That is the most experienced pilots have the simplest system. IFR pilots just do what they are told by ATC- even when to change frequency .
But a VFR pilot flying en route has to constantly look down at the iPad and change frequency to the ATC sector. Then after hearing a pilot say " all traffic Windslow" has look down again and attempt to find out where that place is. Due to up to 13 frequencies on re transmit the location could be 400 miles away and not on the chart area being looked at.
This means less remaining vigilant to see other traffic.
See, I have actually flown across Australia testing out how the system works.
And it doesn't. It's a half wound back stuff up and must be fixed.
