Avsi and waic l.jpg
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 l.jpg
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 l.jpg
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


    Icao role and itu r regional support l.jpg
    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
