Aerospace Vehicle Systems Institute

What is AVSI Aerospace Vehicle System Institute - A cooperative of aerospace industries and

government agencies. Members include Airbus, BAE Systems, Boeing, Bombardier, Embraer, Goodrich, Gulfstream, GE Aviation, Honeywell, NASA, United Technologies, US DoD (observer).

Brings together industry, government and academia to focus on developing improved aerospace vehicles.

Creates an environment for collaboration on R&D; investigates emerging technologies; influences standards and policies to promote cost effective systems development and certification.

What is WAIC An official project of AVSI Radiocommunications between two or more points on a single aircraft. May include integrated wireless components and/or installed components. Part of a closed, exclusive network required for operation of the aircraft. Do not provide air-to-ground or air-to-air communications. Only safety related applications are being contemplated.

Potential WAIC Applications Low Data Rate, Interior Applications:

Cabin Pressure Engine Sensors Smoke Detection Sensor Data (unoccupied and occupied areas)

Low Data Rate, Outside Applications: Ice Detection Landing Gear/Brake Temperature Sensors Engine Sensors

High Data Rate, Interior Applications: Flight Deck/Cabin Crew Video and Audio Air Data Sensors Engine Prognostic Sensors

High Data Rate, Outside Applications Structural Sensor Data Avionics Communications Bus Active Vibration Control

Wireless connectivity can improve flight-safety and operational efficiency, while reducing manufacturing and operational costs. Wireless link for redundancy Reduce aging wiring and associated conditions Weight Reduction Potential – environmental benefits

Increased Reliability Fewer connector pins/failures, cracked insulation, & broken conductors Mesh networks could provide redundancy

Improve Operational Efficiency Ability to obtain more data from aircraft surfaces Less wire maintenance to remediate chafing conditions Simplify and reduce life-cycle cost of airplane wiring Reduced weight should save fuel costs

Importance of WAIC to the Aviation Industry

ITU-R Working Party 5B - Update

WP5B is lead ITU-R Group

WAIC Preliminary Draft New Report Inputs from CEPT, US and Brazil – 4th meeting with inputs

US and CEPT documents almost identical, Brazil provided Glossary of Terms

Technical Characteristics and Operational Objectives

Working Document upgraded to a Preliminary Draft New Report

Next step is to make document a “Draft New Report”, and then Report

Now must start considering whether an Agenda Item is needed

Several Liaison Statements Sent WP5C (Fixed Service) – (37-38 GHz band)

WP7B (Space Services) – (37-38, 22.55-23.15 GHz bands)Slide 5

WAIC Update – 37-38 GHz Band

WRC-12 Agenda Item 1.12 seeks to determine if the aeronautical mobile service can be removed from the 37-38 GHz band

WAIC might be able to use this band Want to protect Space Research and Fixed ServicesWP 5B provided technical information (PDNR) to WP 7B and

to 5C (responsible groups)WP 5B asks whether any of the classifications of WAIC can be

acceptablePreliminary Political Analysis

Most countries will consider keeping AMS allocation if studies support sharing with WAIC

Slide 5

Aerospace Vehicle Systems Institute

WAIC Update – 22.55-23.15 GHz Band

WRC-12 Agenda Item 1.11 seeks to permit the Space Research Service in the 22.55-23.15 GHz band.

Liaison statement to WP 7B sent that states WAIC will not consider this band.

ICAO and Future Course of Action

AVSI has started reviewing potential bands First bands reviewed - see input to ICAO WG-F meeting

4200-4400 MHz 5030-5091 MHz 9300-9500 MHz

Potential Future WRC Agenda ItemFocus on “Aviation” bands

Review current RTCA, EuroCae, ICAO, ITU-R protection criteria. Should make job easier at ITU-R Will require extensive technical analysis, marketing and education of

aviation regulatory bodies

Focus on Bands above 20? GHz

Slide 5

Aerospace Vehicle Systems Institute

Need for ICAO and ITU-R Regional Support

If an Agenda Item is required, then support from APT and ICAO is required

Important that world-wide allocation(s) be obtainedSpectrum usage must fall within ICAO ConventionEquipment certification must have same regulatory benefits as

“avionics” and other aviation equipmentThe Service Definition chosen for WAIC requires support

ITU-R Working Party 5B - Issues

Potential Service Issue What Service will WAIC applications be considered under? – Most likely

Service is Aeronautical Mobile (Route) Service. ICAO and Arab States will most likely insist on this definition
