navigation or performance data and specific functions of Flight Management (revised flight plan,
engine-out, secondary flight plan, etc.). It is also possible to display additional data from peripherals
(Centralized Maintenance System (CMS), ARINC Communication Addressing and Reporting System
(ACARS), Air Traffic Service Unit (ATSU)...). If the flight crew enters data in the MCDU that is not
logical, or is beyond the capabilities of the aircraft, it is disregarded or it generates an advisory
message.
The MCDUs enable backup navigation in the case of dual FM failure.

FLIGHT CONTROL UNIT (FCU)
Applicable to: ALL
The FCU on the glareshield is the short-term interface between the flight crew and the FMGEC. The
flight crew uses it to select any flight parameters, or to modify those selected on the MCDU. It is
possible to engage or disengage autopilots and autothrust functions. It is possible to select different
guidance modes in order to change various targets (speed, heading, track, altitude, flight path angle,
vertical speed).
FM SOURCE SELECTOR
Applicable to: ALL
This selector enables the flight crew to transfer the FMGEC data to the offside MCDU and EFIS
display in the case of an FM failure.
OTHER FLIGHT CREW INTERFACES
Applicable to: ALL
THRUST LEVERS
The thrust levers are the main interface between the Flight Management Guidance and Envelope
Computer (FMGEC), the Full Authority Digital Engine Control System (FADEC), and the flight
crew.
The thrust levers:
Arm the a‐utothrust at takeoff, when the flight crew selects FLX or TOGA
Limit the maximum thrust by their position when autothrust is active‐
Disconnect the autothrust system when the flight crew sets them to IDLE‐
Command the thrust manually when the autothrus‐t is not active
Engage the common modes (takeoff or go‐-around) when the flight crew selects TOGA (or FLX
for takeoff)
Set the autothrust to ACTIVE mode, when they are between IDLE and CL detent (MCT in‐
engine out).
Applicable to: ALL
ELECTRONIC FLIGHT INSTRUMENTS (EFIS)
Two Primary Flight Displays (PFD) and Navigation Displays (ND) provide the flight crew with
full-time flight guidance, navigation and system advisory information for all flight phases. There
is an EFIS control panel at each end of the glareshield and it is used to control both Primary
and Navigation Displays. This panel includes controls to select various modes within the PFD.
A selector enables the barometric altimeter setting to be displayed on the PFD. It is possible to

select various distance ranges on the ND, and two switches enable the display of either the left or
right VOR/ADF bearing pointers on the ND.
Applicable to: ALL
PRIMARY FLIGHT DISPLAYS
The PFDs combine several conventional flight instrument indications on one color display panel,
for the centralized reference of flight data.
This centralized color display includes:
Flight Director attitude guidance targets‐
Armed and engaged modes‐
Navigation and instrument approach information‐
Altimeter setting‐
Barometric altitude‐
System messages.‐
Applicable to: ALL
NAVIGATION DISPLAYS
The flight crew can select five different navigation compass displays:
ARC (map mode)‐
ROSE NAV (map mode)‐
ROSE VOR‐
ROSE LS‐
PLAN.‐
Information displayed on these modes uses the position of the aircraft as a reference point for the
flight plan navigation data (lateral and vertical information).
Applicable to:
RNP PUSHBUTTON
The flight crew uses the RNP pb to control the lateral deviation (L/DEV) scale display on the PFD
during RNP AR (SAAAR or equivalent) operations.
