Galley Insert (GAIN) Subcommittee

Last Update: July 3, 2008

APIM: Standard Interface for Galley Insert Equipment (pdf, 31K)

---

Goal: The goal of the GAIN Subcommittee is to standardize the physical dimensions and electrical interfaces for Galley Inserts to support standard installations.

The primary areas being considered for standardization include:

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

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
