Title: AIDC Implementation in Hong Kong, China

AIDC Implementation in Hong Kong, China
  • APAC/NAT AIDC TF/2 - AIDC Seminar
  • Stanley Lau
  • Ag. Senior Electronics Engineer
  • Civil Aviation Department
  • Hong Kong, China
  • 23 July 2013

Background
  • Hong Kong, China has put AIDC into operational
    use between HK and Sanya since Feb 2007.
  • Standalone system use real-time data from ATM
    System.
  • Further AIDC technical tests have been conducted
    with other ACCs such as Guangzhou, Zhangjiang,
    Taibei
  • HK and Taibei AIDC operation commenced on 16 Nov
    2012.
  • Success in reduction of ATM personnel workload
    and elimination of human errors arising from
    voice communications via Inter Area Speech
    Circuit (IASC).

Operation Efficiency
  • Using subset of core messages, namely, EST, ACP,
    LAM, LRM as well as TOC and AOC with Sanya
    recently (28 Mar 2013) out of the 13 core
    messages as agreed with counterparts in
    accordance with APAC AIDC ICD and ICAO ASBU
    B0-25.
  • Efficiency gained by utilizing AIDC is
    significant. e.g. in Dec 2012, about 29,000
    transactions (HK-Sanya and HK-Taibei) were
    completed, representing the equivalent number of
    IASC calls were saved. Less than 6 of
    transactions reverted to voice, including missing
    flight plans, late/fail AFTN transmissions as
    well as operation needs.
  • Expecting more extensive AIDC usage in new ATMS.

Implementation Issues
  • Different versions of AIDC messages and Cyclic
    Redundancy Check (CRC) initial values (Xmodem,
    Kermit, 0xffff and 0x1d0f) being utilized, AIDC
    partners require to indicate which ICD version
    and CRC initial values during technical testing.
  • LRM and error code/messages feedback from
    counterparts needed to be captured in the Problem
    Message Queue (PMQ) of the ATM System and require
    prompt response to the counterparts e.g. voice
    coordination.
  • AFTN and subsequent ATN network with inherent
    network latency, circuit diversion/re-route or
    system maintenance of the network that will
    affect the timeliness of AIDC messages, which are
    considered as time- and mission-critical.
