  1. Update on Wireless Avionics Intra-Communications (WAIC)ICAO, ACP-WG-W, Montreal Marcella Ost January 22, 2010 ACP WG-W/3 IP-3

  2. 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.

  3. AVSI and WAIC • 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

  4. 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

  5. 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. Slide 5

  6. 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 Slide 5
