The NAV-AID PLUS offers the extra benefit, at little extra cost, of two instruments in one. An in-built circular computer allows you to do your pre-flight and en-route calculations of ground speed, distance and time intervals without the need of another instrument.

Each NAV-AID has for convenience one defined distance scale either WAC 1:1,000,000 or Sectional 1:500,000. No multiple scales to cause confusion - we are all aware of Murphy's Law.

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.

THREE SIMPLE STEPS

Place the centre point 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.

Today’s technology has given us the G.P.S. but V.F.R. still requires visual navigation as the primary method. The NAV-AID RULE or NAV-AID PLUS and Aeronautical chart is all you should require with the comfort that track corrections or diversions are easily taken care of.
