Full title and description

St ARINC CHARACTERISTIC 755-5-2018 — "Multi‑Mode Receiver (MMR) — Digital". This characteristic defines the design, interfaces and performance requirements for a multi‑mode landing system receiver capable of providing flight‑path deviation guidance for approach and landing using ILS, MLS or GNSS/GLS sources; Supplement 5 adds GLS/GNSS annunciations and ARINC 429 label updates.

Abstract

ARINC 755‑5:2018 specifies the functional, electrical, RF and interface characteristics of a digital Multi‑Mode Receiver (MMR) intended for transport aircraft. It covers receiver performance, digital outputs (ARINC 429), RF/antenna requirements, GNSS/GLS precision landing guidance functions, failure monitoring and built‑in test (BITE), airplane personality data, and provisions for test equipment and installation. Supplement 5 integrates annunciation and data validity requirements aligned with RTCA/DO‑253D and updates GLS-related ARINC 429 labels.

Scope

The characteristic applies to digital multi‑mode landing receivers (MMR) that provide proportional deviation outputs and annunciations for precision and non‑precision approaches. It defines form‑factor and connector interchangeability, power and discrete signalling, ARINC 429 data outputs and attributes, RF performance for ILS/MLS/GNSS inputs, GNSS precision/GLS operational modes and monitoring, airplane personality data (APM) formats, differential data link receivers, BITE/OMS provisions, environmental and test requirements, and installation guidance for antennas and interfaces. Supplement 5 specifically addresses GLS/LAAS annunciation, GLS data validity labels, and correction to selected glide‑path angle ranges.

Key topics and requirements

• MMR functional description and operational modes (ILS, MLS, GLS/GLS SBAS/SBAS GLS optional modes).
• RF receiver performance: sensitivity, selectivity, dynamic range, channel requirements and interference handling.
• GNSS/GLS precision landing guidance functions, integrity monitoring (RAIM/PRAIM), and GLS mode handling.
• ARINC 429 data output formats, label usage and attribute definitions (including GLS data and config validity labels).
• Antennas (ILS/MLS/GNSS) characteristics, installation considerations and preamplifier/divider requirements.
• Control, annunciation and audio outputs (mode code audio, failure annunciations aligned to RTCA/DO‑253D).
• Aircraft Personality Module (APM) interface, data-block formats and configuration/data loading requirements.
• BITE, OMS/CFDS interoperability, provisions for automatic test equipment and unit identification.
• Environmental, EMI and test categories; procedures for performance verification, audio output tests and RF/antenna testing.

Typical use and users

Primary users include avionics OEMs, airborne system integrators, aircraft manufacturers, airline technical and certification teams, avionics test/maintenance organizations, and regulatory/certification authorities. The characteristic is used to design, validate, integrate and certify MMR equipment and associated antennas, to define ARINC 429 messaging for flight guidance, and to prepare installation and test documentation for aircraft modification and new production.

Related standards

Relevant and commonly referenced documents include ARINC 429 (data bus definitions and labeling), RTCA/DO‑253D (MOPS for GPS LAAS airborne equipment — annunciations referenced in Supplement 5), RTCA DO‑246(A) and other GNSS/GLS MOPS and DO‑178 series guidance where software assurance is applicable. ARINC 755‑4 (2010) is the previous edition and is superseded by 755‑5 (2018).

FAQ

Q: What is this standard?

A: ARINC Characteristic 755‑5:2018 is the ARINC specification that defines the characteristics, performance, interfaces and test requirements for a digital Multi‑Mode Receiver (MMR) used for approach and landing guidance from ILS, MLS and GNSS/GLS sources.

Q: What does it cover?

A: It covers functional requirements, RF and antenna characteristics, ARINC 429 data outputs and labels, GNSS/GLS precision guidance modes and integrity monitoring, control and annunciation requirements (including DO‑253D annunciations in Supplement 5), APM data formats, BITE/OMS interfaces, environmental and test procedures, and installation/interchangeability guidelines.

Q: Who typically uses it?

A: Avionics manufacturers, aircraft integrators, airlines, certification authorities and maintenance/test organisations use the characteristic to design, integrate, validate and certify multi‑mode landing receivers and to ensure correct ARINC 429 messaging and annunciations for precision approach operations.

Q: Is it current or superseded?

A: The 755‑5 edition (2018) is the current ARINC characteristic for the MMR; it supersedes ARINC 755‑4 (2010). Users should verify with their regulatory/certification authority for any required supplement or amendment when applying the characteristic to a certification program.

Q: Is it part of a series?

A: Yes — ARINC 755 is part of the ARINC family of avionics characteristics and interacts with other ARINC and RTCA standards (for example ARINC 429 for data bus messaging and RTCA DO‑253D for GLS/LAAS annunciation requirements). The characteristic includes attachments and appendices that form the complete specification for MMR digital implementations.
