FMGC Description

The Flight Management Guidance Computer (FMGC) contains a navigation database which provides navaid auto-tuning, position computation, navigational accuracy checks, and flight planning through the Multifunction Control Display Unit (MCDU). The MCDU contains a performance database that provides predictions of fuel, time, distance, speed, and altitude.

Each FMGC is linked to its own onside MCDU, RMP, and EFIS control panel. After entry of the flight plan and other required performance data into the MCDU, the FMGS generates the climb and descent profiles for departure and arrival, provides automatic airplane guidance, and computes current and predicted progress along the flight plan.
