I would recommend this tool without hesitation.

Great tool for learning the ins and outs of air navigational problem solving.

I highly recommend it prior to purchasing the electronic version, you may never need the electronic one after you use this very useful tool!

The E6B metal flight computer is an excellent tool for any flight student learning flight planning.

This thing is a wonder, absolutely outstanding tool for calculating wind angles, ground speed, time in route, distances, magnetic headings, etc
