Full title and description

St ARINC CHARACTERISTIC 755-4-2010 — "ARINC Characteristic 755-4: 2010 — Multi-Mode Receiver (MMR) - Digital". This characteristic defines the desired characteristics, interfaces and performance for an airborne Multi‑Mode Receiver intended to provide final‑approach flight path deviation guidance using ILS, MLS and GLS sources; Supplement 4 adds ILS look‑alike outputs and Final Approach Segment Data Message (FASDM) support for GLS CAT II/III operations.

Abstract

ARINC 755-4 (2010) specifies functional, performance and interchangeability requirements for a Multi‑Mode Receiver (MMR) providing approach and landing guidance from ILS, MLS and GNSS/GLS sources. Supplement 4 introduces ILS look‑alike ARINC 429 outputs to support GLS precision approach operations (GLS CAT II/III) and defines FASDM input labels and related avionics data interfaces.

Scope

This characteristic sets forth electrical, mechanical, environmental, data‑interface and performance requirements for a transport‑category Multi‑Mode Receiver (MMR). It covers ILS and MLS receiver design and performance, GNSS/GLS precision‑landing guidance functions (including integrity and RAIM/PRAIM considerations), ARINC 429 and MIL‑STD‑1553 interfaces, antenna requirements, annunciations and crew indications, airplane personality data (APM/APDM) formats, BITE/automatic test provisions, and data‑link receiver requirements. Supplement 4 specifically extends the MMR outputs to provide ILS “look‑alike” ARINC 429 messages to support GLS precision approach operations and adds Final Approach Segment Data Message (FASDM) definitions.

Key topics and requirements

• MMR functional description and modes of operation (ILS, MLS, GLS, standby, data broadcast modes).
• Receiver performance requirements: accuracy, sensitivity, selectivity, dynamic range and multipath behavior for ILS/MLS/GLS.
• ARINC 429 data outputs (ILS look‑alike outputs) and label/attribute definitions; ARINC 429 bus usage and mapping.
• GNSS/GLS precision landing guidance interfaces, integrity monitoring (RAIM/PRAIM) and GLS operational modes.
• Annunciation and warning requirements (mode status, failure annunciations), including updates to support RTCA DO‑253D annunciation conventions where applicable.
• Antennas (ILS/GLS/MLS/GNSS) and installation considerations, environmental and cooling requirements.
• Interchangeability, form‑factor and connector pin assignments (APM interface, standard interwiring), and maintainability/BITE provisions for automatic test equipment.
• VHF and C‑band differential data link receiver requirements and data‑link interfaces for precision approach augmentation.

Typical use and users

Primary users are avionics manufacturers, aircraft integrators, flight‑control and navigation system designers, certification engineers, and airline technical authorities. The characteristic is used to design, qualify and integrate Multi‑Mode Receivers in transport‑category aircraft and to ensure interoperability with aircraft displays, autopilot/flight‑director systems and ground‑based/space‑based precision approach services.

Related standards

Commonly referenced documents and related standards include ARINC 429 (airborne data bus), ARINC 739 (MCDU/Aircraft personality interfaces), RTCA/DO‑246A (GNSS/GLS guidance MOPS), RTCA/DO‑253D (annunciations for LAAS/GPS equipment) and other ARINC characteristics addressing avionics installation and data‑loading interfaces. ARINC 755-5 (2018) is the later edition that updates and replaces 755-4.

FAQ

Q: What is this standard?

A: ARINC Characteristic 755-4 (2010) is an ARINC/AEEC technical characteristic that specifies the functional, performance and interface requirements for a Multi‑Mode Receiver (MMR) used to supply final approach deviation guidance from ILS, MLS and GNSS/GLS sources.

Q: What does it cover?

A: It covers receiver design and performance (ILS/MLS/GLS), ARINC 429 and other data interfaces (including ILS look‑alike outputs added by Supplement 4), antenna and installation requirements, annunciation and crew indications, airplane personality data formats, BITE/test interfaces and data‑link receiver requirements for precision approach augmentation.

Q: Who typically uses it?

A: Avionics suppliers, aircraft manufacturers and systems integrators; certification and avionics installation engineers at airlines and regulators; test and maintenance organizations that develop or qualify MMR hardware and software.

Q: Is it current or superseded?

A: ARINC 755-4 (2010) has been superseded by ARINC 755-5 (2018). Records from standards distributors list the status of 755-4 as superseded (supersession noted in 2021) with ARINC 755-5 (2018) as the current edition. Users planning new designs should reference ARINC 755-5 (2018) or the most recent ARINC/AEEC release.

Q: Is it part of a series?

A: Yes — ARINC 755 is a characteristic within the ARINC family covering Multi‑Mode Receivers; the “-4” denotes Supplement 4 to the base characteristic (2010 edition). Later supplements/editions are released under ARINC 755 (for example ARINC 755-5: 2018).

Q: What are the key keywords?

A: Multi‑Mode Receiver (MMR), ILS look‑alike, GLS, GNSS, ARINC 429, Final Approach Segment Data Message (FASDM), APM, RAIM, BITE, avionics interfaces.
