Another entry in the endless debate...

I've used Sporty's calculator and of course the aluminum E6B. There are
obviously disadvantages to both, but my flight instructor made the best
argument for the manual version. He showed me that once a relationship
is set, the dial shows you thousands of answers to the same question
with no further msnipulation. Set for 8 gals/hr. How much do I burn in
2.4 hours? How much in 3.9 hours? No more punching buttons. I agree that
wind correction is pretty crude, but it's also easier to visualize.

I equate it to a GPS instead of plotting a course. It's better to have
both. Can't beat a calculator for density altitude.
