Frequency selection through the 3.624.561-02 panel

The panel is designed for setting working frequencies used by VOR, ILS and SP-50 equipment. Frequency selection is made with two rotary selectors: one selector is used for the MHz portion, while the second sets the fractional part of the frequency. This type of layout is typical for cockpit radio-navigation controls because it lets the crew change the required channel quickly and clearly. The selected frequency is shown on the panel by a light indication, so the crew can visually confirm the setting before or during operation.

Mode control for Kurs MP-70 with 3.624.561-02

In the Kurs MP-70 system, the 3.624.561-02 panel is used not only for frequency selection, but also for selecting the required operating mode. The mode switch allows the crew to choose between VOR, ILS and SP-50 operation. This is important because the same control position in the cockpit must support different navigation and landing tasks. In VOR mode, the system works with radio navigation beacons. In ILS or SP-50 mode, the equipment is used for approach and landing guidance, depending on the installed system and airport equipment.

3.624.561-02 with onboard navigation receivers

The 3.624.561-02 works with the onboard receivers and components included in the Kurs MP-70 navigation and landing suite. Its selected frequency and mode are transmitted into the system, where the connected equipment uses them for signal reception and processing. For maintenance or replacement, the panel must be checked together with wiring, illumination, selectors, contacts and the receiving equipment. A fault in the panel may look like an issue with the receiver, especially if frequency selection, indication or switching is unstable.

Cockpit installation of the 3.624.561-02 unit

The panel is made as a standard cockpit control unit and is normally installed in a DZUS-type panel location. This format allows the unit to fit into aircraft radio and navigation control panels without taking excessive space. Since it is operated directly by the crew, the condition of the selectors, mode switch and frequency indication is important. Worn knobs, weak backlight, intermittent contacts or poor readability can create practical problems even if the rest of the Kurs MP-70 system is serviceable.

Identification and supply of 3.624.561-02

When ordering the unit, the full designation 3.624.561-02 should be used. The panel may also be referred to as PU 3.624.561-02, where PU means control panel. Before replacement, the part should be checked against the aircraft parts catalog, Kurs MP-70 documentation and the specific cockpit configuration. It is also important to clarify the required condition, documentation, connector compatibility and whether the unit is supplied as a standalone panel or as part of a larger navigation equipment set.
