The NAV-AID RULE solves the most troublesome aspects of visual navigation, off-course heading corrections and unexpected diversions. This Patented product gives the heading change from present position direct to the destination, or a selected diversion. The NAV-AID has for convenience one defined distance scale of Sectional 1:500,000. No multiple scales to cause confusion.

Todays technology has given us the G.P.S. but V.F.R. still requires visual navigation as the primary method. The NAV-AID RULE and your aeronautical chart is all you should require with the comfort that track corrections or diversions are easily taken care of.THE NAV-AID RULE has been constructed from a special synthetic material of such thickness and flexibility to allow it to be bent without permanent distortion or breakage.


  • Place the centrepoint of the base-line over the present position.
  • Align the base-line with the departure point or last fix.
  • Using the radials read off the number of degrees to alter present heading to fly direct to destination.No need for 1:60 rules or computers!
