An easy-to-use navigation aid for flying on course and time
This unique protractor, developed and copyrighted by NavBox/The Pilot Shop, is flexible and fits into a flight shirt pocket.
Part of it has a special finish. This allows you to put a pencil mark for wind direction and speed, much in the same way as you would have done on a slide graphic computer.
The Windprotractor comes with ample illustrated instructions and examples.
