Navigational database
The FMGS included two copies of a commercial navigational database. The database was updated on a 28-day cycle as a part of normal scheduled maintenance. The investigation established that the navigational database that was current for the flight included a lowest descent altitude for the Melbourne ARBEY ONE ALPHA runway 27 arrival of 2,000ft.
