NAV-AID RULE - DESIGN PATENTS: Australia 51271, Canada 245/30913, U.K. 936201, N.Z. 11461, U.S.A. 21627

The NAV-AID RULE and the NAV-AID PLUS solve the most troublesome aspects of visual navigation, off-course heading corrections and unexpected diversions.

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.

“It really is as easy at that”

• No need for 1:60 rules or computers! The NAV-AID RULE accomplishes the task quickly and easily.
• 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.
• 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 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.
