    Dave,

    Normally I use a pair of 45* protractor triangles to plot azimuths and intercepts but the very tight seating on a 737 means being creative with the plotting tools thus the unusual Helix protractor which will lay down an azimuth on the smallest of tray tables. If graph paper is used to construct a plotting sheet then the Helix protractor can become a compass rose anywhere on the sheet. Index cards are also very handy in tight places for producing 90* angles and subbing for a divider by marking distance on the edges.

    I'm interested to see your Helix protractor. Can you describe your use of it and if/why you prefer to a more conventional plotter?
