In the instrument landing procedure, the direction of the Runway of an airport indicated by a landing course transmitter that uses ILS (Instrument Landing System) Fan-shaped with low power radiated upwards with a radiation field of a certain shape in width and depth perpendicular to the flight path.

Each system provides information to the pilot in the form of a pointer on a directional instrument such as a ADF indicator, a VOR indicator, or an RMI indicator (Remote Magnetic Indicator), a daughter unit to a magnetic master compass.

Existing indicators of these types generally have three characteristics. For one, have such indicators a compass rose, which can either be rotated by hand or rotated by a servomechanism, which is connected to a compass system so that the course of the aircraft is below the lay line. To the second, the instruments represent a top view of an airplane in the center of the turntable. Finally These instruments include a needle that threatens itself in the center of the instrument and into the Points in the direction of the selected navigation transmitter station.

When using these indicators, the pilot must visually identify and relate to the correct position set the selected station by constantly doing various calculations and deliberations. Of the The pilot must then use the results of these considerations in the

Further modification of the device is possible insofar as a transparent card is applied to the front screen which can be rotated with the compass rose and the geographical area around the respective transmitter represents.

When an LED lights up, it shows (on the map) the location over which the aircraft is located. It dangerous high points are immediately recognizable and can be avoided.

Another modification can be made using known technology by instead of the light-emitting diodes a system is used, which the pivot point of the pointer 7, preferably an airplane symbol, slides along the needle 5 so that the position of the fulcrum 8 from the axis of the shaft 18 the Represents the distance of the DME instrument. With In other words, the pivot point can be positioned where the LED display would appear. Alternatively, the needle 5 can slide through a tube at the end of the shaft 18, during the fulcrum remains fixed on the needle 5. The result is the same; the fulcrum 8 on the needle 5 represents the DME removal. These embodiments can, for example, with suitable switches, motors and Translations can be performed as would be apparent to those skilled in the art.
