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.

  • 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
importance of waic to the aviation industry
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
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)


  • 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

icao role and itu r regional support
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
