+7 (812) 702-60-98 FOR AIRLINES AIRFIELDS AND HE SCORE SERVICE ABOUT COMPANY NEW "OLD" ACCESSORIES IN THE STORE! New accessories, the Navigation ruler NL-10mk and the Navigational protractor, have appeared on the sale of our online store . No wonder it sounds, but at a time when even self-made aircraft assembled by aviation enthusiasts often boast an aviation navigator , or a tablet with navigation programs , the devices that stood at the origins of air navigation are still finding their users. Navigation ruler NL-10mk is a portable calculating instrument designed for navigation and other calculations. The navigation ruler consists of three main parts: the body, the engine and the sight. The body of the ruler consists of two bars, which are interconnected with metal clips. The degree of friction is selected by changing the deflection of the metal braces. The ruler scales are printed on white plastic (rigid PVC) by screen printing. The visor covers the body of the ruler from both sides. On both sides of the sight, there are marks for taking the reading. The navigational protractor is a measuring tool and is designed for drawing and measuring angular and linear values. The protractor is made of transparent plastic (polyethylene terephtolate) with a thickness of 0.7 mm and is half a square with a side of 125 * 125 cm. There are three scales on the protractor. The first goniometric scale is marked on the two small sides of the triangle from zero to 180º with a 1º division. The second goniometric scale is marked inside the first scale from 180º to 360º, also with a 1º division. The strokes are multiples of 5º longer. The center of the scales is located in the center of the triangle. The third scale is linear, printed on the long side of the triangle, from zero to 154mm. Graduation 1mm. Digitized through 1cm. The strokes in multiples of 5 mm are twice as long. In the center of the protractor, a graphical and formulaic relationship between conditional, magnetic and true courses is plotted.
