Looking back through my log books some of my most interesting flights were using 1 mil maps with nothing on them. Flying across the Australian outback from MT Isa to Alice,Ulura to Port Augusta and Adelaide,Ceduna,Kalgoorlie to Perth.
This in 1989 with no navaids just a map and compass. GPS has taken a lot of the navigation skill out of flying in my opinion. Long distances on dead reckoning.
In many respects it mirrors the average home. Switch off the electricty and the phone,internet,heating cooking etc is gone.
A chart is a good solid old fashioned method of finding your way from A to B that will never let you down.
