Agenda item 1.17 – Spectrum and regulatory requirements for WAIC

Outline >Background >Summary of Australian Position >Developments during WRC-15 >Summary of Outcomes >Future Impacts

Background (1) >AVSI developing WAIC to:  improve flight-safety & operational efficiency  reduce manufacturing & operational costs >Current aircraft comms systems require complex electrical wiring & harness fabrication, adding weight to the aircraft & increased fuel costs A350: electrical systems installation Typical wiring installation in A380 crown area (above ceiling panels)

Background (2) >WAIC systems only used for safety-related aircraft applications >ITU-R completed its work on this issue  Approved all Reports/Recommendations required for WRC-15  A single Method included in the CPM Report >The single Method supported by Australia and the APT

Summary of Australian Position >Australia supported the single Method in the CPM Report  APT Common Proposal to WRC-15 also supported  Mr D’Amico (AUS) the APT AI 1.17 Coordinator at WRC-15 >The single Method in the CPM Report  Supported an AM(R)S allocation in MHz  Supported the establishment of appropriate regulatory & procedural processes to support the use of WAIC in the band >APT Common Proposals  Primary allocation for AM(R)S at MHz band  New Resolution on use of WAIC  New footnote to limit the use of AM(R)S to WAIC systems  Modified/new footnotes to maintain status of ARNS, EESS & SRS  Suppression of Resolution 423 (WRC-12)

Developments during WRC-15 (1) >All input documents supported the single Method in CPM Report  CEPT and CITEL documents had some minor differences >SWG4A2 on a.i (chaired by Dave Kershaw (NZL))  Met once and developed a document based on single Method o CEPT and CITEL agreed to align with the CPM text  Considered the regulatory point identified in the Director’s Report on inconsistency between definition of AMS in No and No o No defines the AMS as a mobile service b/w aeronautical stations and aircraft stations, or b/w aircraft stations o No limits AM(R)S to communications b/w aircraft and aeronautical stations, without mentioning communications b/w aircraft stations  Agreed inclusion of resolves 4, stating “that No shall not apply for WAIC systems”

Developments during WRC-15 (2) >WG 4A  Russia queried contradiction between resolves 1 and 4 in the new Resolution with respect to No o Offline discussions resulted in resolves 1 being modified o proposals agreed & forwarded to COM 4 >COM 4  The 3 rd COM 4 meeting approved proposals >Plenary  The 3 rd plenary meeting approved all AI 1.17 proposals >Work completed on Friday of the 1 st week of the conference

Summary of Outcomes >Work on this item progressed quickly at the conference >All APT (and Australian) proposals adopted by WRC-15 >The conference agreed to:  ADD a primary AM(R)S allocation to the MHz band  ADD a new Resolution (COM4/1 (WRC-15))  ADD No. 5.A117 limiting use of MHz band by AM(R)S to WAIC systems in accordance with recognised international aeronautical standards and the new Resolution  MOD No to maintain the use of the MHz band by ARNS exclusively for radio altimeter  ADD No. 5.B117 to maintain the status of passive sensing in EESS and SRS in the MHz band  SUP Resolution 423 (WRC-12)

Future Impacts >Considerable work is required before WAIC systems will be incorporated on aircraft  EUROCAE and RTCA standards  ICAO SARPs >Equipment manufacturers of WAIC systems will have to demonstrate compliance  Certification with CASA >WAIC systems in Australia will fall under the Aircraft and Aeronautical Mobile Stations Class Licence
