MCDU, FMC, FMS, Apakah itu?

                  Pertama kali naik Pesawat, pasti kita berfikir "bagaimana sih pesawat bisa terbang?" dan "Di cockpit ada apa sih?" Ya, mungkin itu sebagian dari pertanyaan yang mungkin terfikir (Menurut pengalaman saya sendiri :D ). Setelah saya baca-baca artikel tentang dunia aviasi dan bermain game Flight Simulator, Saya sedikit mengerti apa yang ada di dalam cockpit dan apakah fungsinya.

                Saat ini, Saya akan membahas salah satu bagian dari dalam cockpit, yaitu Flight Management Computer / Flight Management System. Jadi, apa sih fungsi FMC / FMS itu? Berikut saya kutip dari wikipedia :  

 "A flight management system (FMS) is a fundamental component of a modern airliner's avionics. An FMS is a specialized computer system that automates a wide variety of in-flight tasks, reducing the workload on the flight crew to the point that modern civilian aircraft no longer carry flight engineers or navigators. A primary function is in-flight management of the flight plan. Using various sensors (such as GPS and INS (Inertial Navigation System) often backed up by radio navigation) to determine the aircraft's position, the FMS can guide the aircraft along the flight plan. From the cockpit, the FMS is normally controlled through a Control Display Unit (CDU) which incorporates a small screen and keyboard or touchscreen. The FMS sends the flight plan for display to the Electronic Flight Instrument System (EFIS), Navigation Display (ND), or Multifunction Display (MFD)."

              Menurut salah satu profile Pilot Airbus A320 di Instagram (@pilotata320) yang telah memberikan izin untuk di copy ke Blog saya :

            Multipurpose Control and Display Unit.

            "Two MCDU are installed on the pedestal for flight crew loading and display of data.
            The use of the MCDU allows the flight crew to interface with the FMGC by selection of a flight plan for lateral and vertical trajectories and speed profiles. The flight crew may also modify selected navigation or performance data and specific functions of Flight Management (revised flight plan, engine-out, secondary flight plan, etc.). Additional data from peripherals CFDS (Centralized Fault Display System), ACARS (Aircraft Communication Addressing and Reporting System), Air Traffic Service Unit (ATSU) can also be displayed. Data that is entered into the MCDU that is illogical or beyond the aircraft capabilities will either be disregarded or will generate an advisory message.

            The MCDUs allow the activation of the back–up navigation in the case of a dual FM Failure."

                Sekian penjelasannya, Mohon dikoreksi apabila ada kesalahan dalam penjelasannya. Maklum, Pengetahuan saya di dunia aviasi masih "cetek".

                Those who doesn't understand with the written language above, you can translate it. Thanks for reading and Thanks for @pilotata320 to let me copy the explanation.
