Description

Navigation instrument for course and location determination

The innovation concerns a device for course and location determination, preferably in aviation, it can also si ^ igiges in the Used for shipping.

In aviation under visual flight conditions, the pilot usually uses a course triangle to determine course and location. The intended course or the point fire positions are entered on a map. The number of degrees is determined with the course triangle by placing it at an intersection of the course line with a longitude circle. This method is particularly laborious during the flight, especially since the radio beacon line usually has to be determined computationally in the case of internal bearings from the aircraft to the bearing station.

The novelty was therefore based on the task of a simple device to create that is efficient and inexpensive to manufacture and easy to use.

According to the invention it is proposed that on a circular, visible disc (1) with a diameter of preferably approx. 15 cm, which has a 360 ° division (2)) and a right-angled crosshair (3); has, several pointers (4, 5, 6) of preferably about 20 cm in length zv. which can be rotated independently of one another around the center point (7) of the disc (1).

A location can then be determined in the following simple manner be performed;

With a direction finder (VOR or ADF) available on board, the angles from the plug tool to two different direction finder stations are determined (with any necessary consideration of the windward angle and the location misalignment), The degrees are with the Pointers (5) and (6) set on the scale (2) of the disc (1). The disc (1) is then placed on the map that the Go pointer through the two bearing stations and the crosshairs (3) of the disc (1) parallel to the longitude and latitude of the The map is located - the center (7) of the disc (1) is then the location «

With the pointer (4) the heading can be set and the The plug direction is immediately visible on the map. With the help of a Distance ska la (8) on the pointer (4) can immediately determine the distance can be read from the current position to the next destination.

The particular advantage of determining the position with the help of the invented device is that it can be repeated continuously without having to calculate one or more new course lines and enter them on the map.

If the aircraft is moving on a known course line, that is The location can be found immediately with the help of a single VOR bearing, while the disc (1) with the crosshair (3) parallel to the longitudinal

and latitude η of the map so placed on the course line is that the pointer (5), which is set to the number of degrees of the bearing, goes through the bearing station.

The advantage of this method is that the location on a known course line can be determined at any time with the help of the invented device without intermediate bills , while with the previously common methods only the so-called transverse bearing is possible simply and without intermediate calculation.

With the help of the invented device, VPR pliers can use the on-board existing VOR and ADF devices much better and more
