Subcommittees & Working Groups
Galley Insert (GAIN) Subcommittee
ARINC Project Initiation/Modification (APIM)
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 812A: 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 Specification 810: Definition of Standard Data Interfaces for Galley Insert (GAIN) Equipment, Physical Interfaces and ARINC Specification 812A: 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
Work Program
Further improvements will be made to ARINC 810 and ARINC 812A as needed.
Next Meeting
AEEC, AMC, and FSEMC are aviation industry activities organized by ARINC Industry Activities, an industry program of SAE Industry Technologies Consortia (SAE ITC)®, to establish consensus technical standards, known globally as ARINC Standards, and develop shared technical solutions that no one organization could accomplish independently.
