BK-1
Aircraft Switching Unit
Description
BK-1 aircraft switching unit
BK-1 is the Latin catalogue form of the Cyrillic БК-1 equipment block. Open aviation listings confirm the designation but do not uniquely establish which system or series this card represents. Other records use БК for switching or control units in several unrelated installations, so a generic abbreviation alone is not sufficient to assign BK-1 to RSBN, DISS or another complex.

BK-1 role with ANU and DISS
An aviation training manual and a specialist aircraft-instrument forum identify БК-1 as the switching unit of the automatic navigation device ANU, operating together with the Doppler velocity and drift measuring system DISS. In that navigation chain the unit provides the required switching between cooperating equipment; it is not a DISS sensor or navigation computer. Its proper context is aircraft avionics.
BK-1 designation and compatibility
Use the complete plate marking, including any series, suffix or drawing number not visible in the catalogue title. BK-1, BK1, БК-1 and БК1 are search variants of the same base designation. The confirmed ANU/DISS context does not make industrial load-limiter blocks or unrelated domestic switching products equivalent. Verify the installed ANU and DISS execution, plate, connectors and aircraft wiring.
Inspection and ordering
Inspect the enclosure, connectors, keys, contacts, mounting hardware, seals and identification plate. Do not energize the unit until the exact supply and pinout are confirmed. An enquiry should include photographs of every marking, the source aircraft or system, series, quantity, condition and documentation. Functionally adjacent navigation switching units are available under Electronic Control Units, but cross-sells do not indicate interchangeability.
BK-1 documented navigation interfaces
The technical description identifies the ANU as an automatic navigation device and DISS as the cooperating Doppler velocity-and-drift measuring system. BK-1 is the switching block between equipment in that chain. The installation drawing, connector allocation, supply and number of switched channels depend on the ANU/DISS modification, so those values are not transferred from a different BK-1 execution.
