Aerospace Vehicle Systems Institute
AVSI and WAIC
 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.

 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

Importance of WAIC to the Aviation Industry
 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

ITU-R and ICAO Lead Groups
WP5B is lead ITU-R Group
WAIC Preliminary Draft New Report
 Technical Characteristics and Operational Objectives
 Working Document adopted as a Preliminary Draft New Report (Nov. 09)
 Next step is to approve document as a “Draft New Report” (May 10),
and then Report (Nov. 10)
ICAO WG-F
 Working closely, updating, receiving guidance and feedback.
Regional Efforts
 Engagement in regional regulatory forums in Europe (CEPT), Americas
(CITEL), Asia (APT). Plans to present to Arab States and ATU in 2010.

ICAO Role and ITU-R Regional Support
 Depending on how ITU-R work progresses, and whether the option of a
WRC 2015/16 Agenda Item is pursued, support from Regions and ICAO
will be essential.
 Important that world-wide allocation(s) be obtained
 Spectrum usage must fall within ICAO Convention
 Equipment certification must have same regulatory benefits as “avionics”
and other aviation equipment
