ARINC 791P2

Purpose of this Characteristic

This document sets forth the desired characteristics of the MarkI Aviation Ku-band and Ka-band Satellite Communication (satcom)System intended for installation in all types of commercial airtransport aircraft, referred to as an ARINC 791 satcom system.

The intent of this document is to provide guidance on the form,fit, function, and interfaces of the ARINC 791 satcom system.

This document also describes the desired operational capabilityof the equipment needed to provide a broadband network that can beused for data, video, and voice communications typically used forpassenger communications and/or entertainment.

The ARINC 791 satcom system is not intended, at this writing,for any required aviation safety functions.

The key goal of this characteristic is to promoteinterchangeability at a number of levels, as shown below, with theaim of minimizing airline life cycle costs:

• Aircraft Manufacturer Interchangeability: the same equipmentcan be fitted to aircraft built by different aircraftmanufacturers.

• Aircraft Type Interchangeability: the same equipment can befitted to a large number of different aircraft types.

• Equipment Manufacturer Interchangeability: equipment fromdifferent manufacturers can be fitted to standardized aircraftprovisions.

• Frequency Band Interchangeability: the same aircraftprovisions can be used for either Ku-band or Ka-band equipment.

• Satellite System Interchangeability: one Ku-band antennasubsystem can be used for different Ku-band satellite systems andthe same Ka antenna subsystem can be used for different Ka-bandsatellite systems. That is, in the future an airline could changetheir satellite provider (provided that the frequency band is notchanged) and could reuse an antenna subsystem, although a new Modemand System Manager (Modman) would be required.

Note: Outside Antenna Equipment (OAE), the Ku/Ka-band RadioFrequency Unit (KRFU) and the Ku/Ka-band Aircraft Networking DataUnit (KANDU) (which are collectively known as the AntennaSubsystem) and Modman are described in Sections 3 to 6.

• Antenna Subsystem and Modman Interchangeability: a consequenceof Satellite System Interchangeability is that the AntennaSubsystem can be sourced from one supplier and the Modman can besourced from a different supplier.
