And of course don't forget we can open the whole debate again about how a map and stopwatch along with the mental arithmetic are better for navigation than a GPS and radio aids.......
Personally I use a CX-2, cheap cheerfull and easy to use and in the air I use the half wind rule.
The Whizzy wheel should be confined to a glass case in a musium somewhere along with the slide rule.
The brainiacs in industry were quick to drop the slide rule in favour of the computer realising how it improved things, perhaps we should also move into the 21st century as well instead of keeping flying in the dark ages.
