Galley Insert (GAIN) Subcommittee

Last Update: July 20, 2010

Co-Chairman: Ralph Schnabel – Airbus
Co-Chairman: Scott Coburn – Boeing
APIM 03-009:
Standard Interface for Galley Insert Equipment (pdf, 31K)


Goal: The goal of the GAIN Subcommittee is to standardize the physical dimensions, electrical interfaces, communication protocol, qualification test guidelines, and maintenance provisions for Galley Inserts to support standard installations. The primary areas of standardization include:

  • Standard wiring
  • Water connectors
  • Electrical connectors
  • Dimensions
  • Interfaces (Physical and Data)
  • Galley mounting rails

ARINC Specification 810: Definition of Standard Data Interfaces for Galley Insert (GAIN) Equipment, Physical Interfaces and ARINC Specification 812: Definition of Standard Data Interfaces for Galley Insert (GAIN) Equipment, CAN Communications have been developed to define galley equipment, component interfaces and communications data.

These guidelines and principals are defined in ARINC Specifications 810: Definition of Standard Data Interfaces for Galley Insert (GAIN) Equipment, Physical Interfaces and 812: Definition of Standard Data Interfaces for Galley Insert (GAIN) Equipment, CAN Communications.

Scope: The scope of the project is to cover all existing functional catering components (i.e., beverage makers, ovens, refrigerators, trash compactors, etc.) with future plans to include emerging catering components (e.g., ice makers, glass and dish washers, multi-beverage dispensers, etc.

Benefit: Standardization provides common installation provisions for commercial air transport multi and single aisle aircraft beneficial to the airlines, airframers, and suppliers.

The benefits are in real interchangeability of GAIN units:

  • All space envelopes, dimensions, connectors, and tolerances are standardized
  • Modular GAIN concepts, as changing configuration is assured, for example:
    • Coffee Maker <> Espresso Maker
    • Freezer <> Oven
  • ARINC sized equipment fits into existing common Galley compartment
  • Standard connector pin layout
  • Minor technical modifications needed on only ~60% of current galley
  • Standardized data bus (CAN bus) providing connectivity to the aircraft system interfaces and BITE

AEEC General Session (October 2008) Update:

The 2009 work program includes the development of Project Paper 813: GAIN Qualification and System Test Guidance. Additionally, further improvements will be made to ARINC 812 data transfer, data loading, network monitoring and master control unit functionality. A computer-readable ARINC 812 data base file will be developed as an open-source XML file that will be made available to various suppliers. The definition of the pin programming personality module will be included in ARINC 810. Galley equipment design and integration will be defined in Project Paper 814. Guidance for galley maintenance will be defined in Project Paper 815.

Draft 2 of Supplement 3 to ARINC Specification 810: Definition of Standard Interfaces for Galley Insert (GAIN) Equipment, Physical Interfaces

Draft 3 of Supplement 2 to ARINC Specification 812: Definition of Standard Data Interfaces for Galley Insert (GAIN) Equipment, CAN Communications
