Kurs MP-70 Litera 13

Performance Specifications of the Kurs MP-70

Cat IIIa approach capability: 30 ft decision height, 200 m RVR. Three operating modes selectable from the pilot console: VOR en route, localizer-only approach, and full ILS coupling with autopilot. Output signals: 28 V DC discrete, AC sine-wave bearing data, ARINC-style serial on modernized blocks. Built-in test equipment runs the preflight self-check. Detailed diagnostics come out of the maintenance connector on the back of the receiver. The Kurs MP-70 mode-control assembly uses electromechanical relays in original units. Modernized variants moved to solid-state switching, which is worth noting if you are sourcing replacement relay sets for the older boxes.

Compatible Aircraft for the Kurs MP-70

Original installation list: Tu-154, Il-62, Il-76M, Il-86, Yak-42, An-22, An-24, An-30, An-32, An-124, and the Mi-8MT helicopter (Mi-17 export). Configuration is not identical across all platforms. Antenna placement, indicator type (5-inch HSI for transports, smaller integrated cluster for helicopters), and autopilot interface vary by airframe. A receiver pulled from one platform will not necessarily plug into another without an adapter harness. Confirm the part marking on the unit against your aircraft's documentation before placing an order. We can supply wiring data for most cross-platform conversions if your installation is non-standard.

Litera Numbers Across the Kurs MP-70 Family

The Kurs MP-70 family went through several production runs during its service life. Literas 1 through 14 are the main variants seen in the field, with Litera 13 being the most common configuration on late-production Mi-8MT and Tu-154 airframes. Each Litera has its own connector pinout, antenna match, and acceptance documentation.

The Litera number is stamped on the data plate on the side of the main receiver case. Cross-Litera installations are not uncommon in fleets that have been through several overhauls, but they require updated paperwork and complicate audit trails. If your aircraft documentation calls for a specific Litera and you receive a different one, the box may still work but the paperwork chain breaks.

The unit also shows up in some documents as "Kurs MP-70" or "Kurs-MP70". Match by part number rather than spelling.

Ordering Kurs MP-70 Modules and Replacements

We stock new-old-stock units (boxed, unused, controlled storage) and overhauled cores with current acceptance documentation. Common modules ship within a week: VOR receiver, standard 5-inch indicator heads, mode-control assemblies. Typical turnaround on a Kurs MP-70 receiver overhaul is 2 to 3 weeks if the unit is not damaged beyond standard work. Longer if there is corrosion or impact repair. Exchange-pool arrangements work well for fleet operators with consistent demand: ship a serviceable core in, get a tested replacement out, minimum AOG time. Include the part numbers from your aircraft's logbook in your enquiry. Documentation supplied on request: operations manual 6G1.000.084 TO plus airframe-specific schematics.
