The Manila Aeronautical Data Communications Center (MADCC) is concrete result of the evolution of data communications. The most efficient, cost effective,  and secured form of aviation communications that utilized the latest in computer and networking technology to satisfy the demand of air safety and economy. The new AMHS system being used is a remarkable feat in hardware and software design since most of the components are COTS or commercial off-the-shelf whereby readily available in the market. Manila ADCC formerly called the Manila Aeronautical Fixed Service (MAFS) Station is currently tasked to provide Aeronautical Fixed Telecommunication Network (AFTN) and Aeronautical Message Handling System (AMHS) service primarily for the safety of air navigation and for the regular, efficient and economical operation of air services.

Area of Responsibility. The Manila ADCC is one of the major communications facilities of the Air Traffic Service. It is the central data communications unit of all ATS facilities. The MADCC link’s all airports’ ATS facilities to enable the exchange of vital aeronautical information such as NOTAM, weather reports, flight plans, departure and arrival messages, position reports and other messages important to aviation. MADCC is connected to four (4) Asia-Pacific countries that serve as gateway to worldwide link to other ICAO member states for the relay and exchange of the aeronautical messages.

Location. The Manila ADCC is currently located at the first floor of the Philippine Air Traffic Management Center (ATMC) Building, Civil Aviation Authority of the Philippines, Old MIA Road, Pasay City.

Hours of Operations. MADCC operates 24 hours a day, 7 days a week. It operates and provides Air Traffic Services via AFTN/AMHS with three shifts of 8 hours each manned by at least three (3) highly qualified personnel per shift headed by a shift supervisor. 

  • Shift 1 – 7:00 A.M. to 3:00 P.M. (2300 – 0700 UTC)
  • Shift 2 – 3:00 P.M. to 11:00 P.M. (0700-1500 UTC)
  • Shift 3 – 11:00 P.M. to 7:00 A.M. (1500-2300 UTC)

Organization. The MADCC is under the Aeronautical Information and Communications Department (AICD), together with Air Traffic Control and Airspace Management Department (ATCAMD), and Air Traffic Planning and Progression Department (ATPPD) make up the Air Traffic Service (ATS). The ATS together with Air Navigation Service, Aerodrome Development and Management Service, Flight Standards Inspectorate Service, Civil Aviation Training Center, and Aircraft Accident Investigation and Inquiry board are the major services of the Civil Aviation Authority of the Philippines.

    • messages  originated  by  an  aircraft  operating  agency of
    • immediate concern to aircraft in flight or preparing to depart;
    • meteorological messages restricted to SIGMET information;
    • special air-reports,  AIRMET  messages,  volcanic  ash; and
    • tropical cyclone advisory information and amended forecasts.
  4. Meteorological messages (priority indicator GG, non-urgent) shall comprise:
    • Messages concerning forecasts (e.g. terminal aerodrome forecasts (TAFs), area and route forecasts;
