With additonal in-built circular computer solving off-course heading corrections and unexpected diversions. Distance scale of WAC 1:1,000,000 The NAV-AID PLUS solves the most troublesome aspects of visual navigation, off-course heading corrections and unexpected diversions and 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. 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 or WAC 1:1,000,000. No multiple scales to cause confusion. 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 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. THREE SIMPLE STEPS 1.Place the centrepoint of the base-line over the present position. 2.Align the base-line with the departure point or last fix. 3.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! The NAV-AID RULE accomplishes the task quickly and easily. from SIFEBA Products, 100% Australian!
