Introduction to the FCU Software application example
The FCU Software application is an interactive software prototype of the Flight Control Unit (FCU) of the Airbus A380.
The FCU Software application is an interactive software prototype of the Flight Control Unit (FCU) of the Airbus A380.
The FCU is an interactive hardware panel with several different buttons, knobs, and displays. The FCU allows flight crew to manipulate the auto-pilot parameters (e.g. altitude, speed and heading) as well as setting information to be displayed on the Navigation Displays (ND). One ND is available for each pilot.

The FCU Software is composed of two main interactive pages:
The FCU Software is composed of two main interactive pages:
- EFIS_CP: Electronic Flight Information System Control Panel for configuring piloting and navigation displays
- EFIS_CP: Electronic Flight Information System Control Panel for configuring piloting and navigation displays
- AFS_CP: Auto Flight System Control Panel for the setting of the autopilot state and parameters
- AFS_CP: Auto Flight System Control Panel for the setting of the autopilot state and parameters

The right side of the EFIS Control Panel is dedicated to the configuration of the Navigation Display. Thee top part provides buttons for displaying navigation information on the cockpit displays. The ComboBoxes at the bottom allow the pilot to choose display modes and scale.

The left side of the EFIS CP is dedicated to the configuration of the barometer settings. This panel is composed of several widgets:
- two CheckButtons enable pilots to select either Standard (STD) or Regional Pressure Settings (QNH) mode.
- two CheckButtons enable pilots to select either Standard (STD) or Regional Pressure Settings (QNH) mode.
- When in QNH mode, a number entry widget (EditBoxNumeric) enables pilots to set the barometric reference.
- When in QNH mode, a number entry widget (EditBoxNumeric) enables pilots to set the barometric reference.
- a button (PushButton) enables pilots to switch the barometer units between inches of mercury (inHg) and hectopascal (hPa). When switching from one unit to the other, a unit conversion is triggered, and the barometer settings value on the display is updated accordingly. When the barometer unit is inHg, the valid range of values is [22, 32.48]. When the unit is hPa, the valid range is [745, 1100]. If the entered value exceeds the valid value range limits, the software automatically adjusts the value to the minimum (when over-shooting the minimum valid value) or the maximum (when overshooting the maximum valid value).

AFS_CP
AFS_CP
The AFS_CP is dedicated to the setting of the different parameters of the autopilot.For example it can be used to change the aircraft route by modifying the heading and/or flight level.

The autopilot can be engaged with the buttons (PushButton) AP1 and AP2. If Autopilot 1 is engaged, three green bars are displayed on the PushButton AP1. If this is disengaged, three black bars are displayed in it. The behavior is the same for engagement of autopilot 2.

When one of the two autopilots is engaged, the pilot can set them up by managing different parameters : speed, course or trajectory, altitude, climbing speed or trajectory angle.

Interactions with the FCU Software
Interactions with the FCU Software
Pilots interact with the FCU Software via the Keyboard and Cursor Control Unit (KCCU), that integrates a keyboard and track-ball. When starting the descent (before landing), pilots may be asked to configure the barometric pressure to the one reported by the airport. The barometric pressure is used by the altimeter as an atmospheric pressure reference in order to process correctly the aircraft altitude. To change the barometric pressure, pilots select QNH mode, then select the pressure unit (which depends on the airport), and then edit the pressure value in the EditBoxNumeric.
