RM 855 radio management unit 7013270-985

7013270-985 is the exact Part Number for this BendixKing / Honeywell RM 855 radio management unit. The unit provides a centralized cockpit display and control interface for compatible aircraft radio and navigation equipment. This card is tied to the photographed configuration and complete suffix, rather than serving as a generic listing for every RM 855 version or a visually similar member of the same family.

The source listing identifies Part Number 7013270-985 as a Honeywell RM 855 TSO-approved radio management unit supplied in repaired condition. The photographed front panel confirms the Honeywell branding and RM 855-style control layout. Exact electrical, dimensional and interface specifications were not confirmed in reliable open manufacturer documentation for this suffix and are therefore not inferred. The identification information is important because voltage, lighting, software, hardware options, certification and connector configuration can differ across related versions. The complete Part Number and the approved technical record must be checked together before purchase or installation.

Operational role and system function

The RM 855 places radio-management selections, tuning, stored-channel access, identification and supported navigation-related controls in one crew interface. The buttons marked SQ, DIM, 1/2, STO, ID, PGE, TST and DME visible on the photographed unit indicate its control role, but the panel relies on connected radio equipment to perform transmission, reception and navigation processing. In service, the unit depends on the integrity of its associated sensors, antennas, transceivers, control panels, displays, data buses, wiring, power and grounding. A reported fault at the unit can therefore originate elsewhere in the connected chain, and troubleshooting should follow the approved aircraft and equipment procedures.

The practical role of RM 855 is to perform its defined function while exchanging required signals with compatible equipment. It cannot replace missing system components and should not be evaluated as an isolated consumer device. Controls or connectors visible in photographs do not prove that every possible function is enabled in a particular aircraft installation.

Installation and connected equipment

A complete installation requires compatible remote radios or navigation units, aircraft power and ground, the correct mounting and connector arrangement, lighting and data-bus wiring defined by the airframe design. Software or configuration compatibility, supported radios and pin allocation must be verified from the aircraft equipment list and applicable Honeywell documentation. A rack, backplate, connector kit, antenna, wiring, cooling hardware or other accessories are not assumed to be included unless they are expressly listed in the quotation. Similar panel dimensions or family names do not prove electrical or approval compatibility.

Before installation, technicians should compare 7013270-985 with the removed unit, aircraft equipment list, wiring diagrams, installation manual and modification records. Panel space, mounting depth, connector keying, pin allocation, circuit protection, lighting, ventilation, data format and configuration settings all require confirmation. Any substitution must be supported by approved data.

Configuration checks for 7013270-985

The suffix in 7013270-985 is part of the product identity. Software level, modification status, database requirements, embedded options, voltage and certification can affect compatibility even when two units look alike. These checks are especially important in aircraft that have accumulated supplemental approvals, avionics upgrades or wiring changes over time.

Incoming inspection should verify the manufacturer plate, housing, connectors, locking features, controls, display or indicator face, fasteners and evidence of unauthorized modification. Functional testing should use the approved bench procedure for the exact model and suffix. Installation and return to service remain the responsibility of appropriately authorized personnel.

Repaired condition, ordering and support

This 7013270-985 RM 855 is offered in Repaired condition from partner stock with a six-month warranty. Partner stock should be reconfirmed at quotation because allocation can change. The available serial number, current test status and release documentation for the specific unit are confirmed before order acceptance.

For an inquiry, specify Part Number 7013270-985, model RM 855, required quantity, destination and documentation requirements. Including the aircraft type and removed-unit Part Number helps prevent configuration errors. Related avionics can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Products shown there are related catalog positions, not interchangeable replacements unless approved technical data explicitly says so.
