EASA learning objective 022.11.03.01.01 states: ‘Describe typical data that may be provided by the FMS: lateral and vertical navigation guidance; present position; time predictions; fuel predictions; altitude/flight level predictions.’

The flight management system (FMS) controls the navigation and automatic flight guidance functions of the aircraft. Lateral (2 dimensions) and vertical (3rd dimension) trajectories can be pre-programmed and the FMS will then calculate time predictions (4th dimension)

Pilots will input the required lateral and vertical flight plan together with performance information via the FMS CDU to enable them to efficiently manage automatic guidance functions and aircraft performance during the flight.
The FMS incorporates various components such as a Flight Management Computer(FMC), Inertial Reference System(IRS), Autopilot/FlightDirector System (APFDS), Autothrust (A/T) and an interface with the pilots called a Command Display Unit(CDU) or Multi Function Control and Display Unit (MCDU).

The FMS does not provide graphical representations of aircraft systems or checklists.
