EFIS Control

!!! note "API Documentation: EFIS Control Panel"

Description

This panel controls:

  • Desired ND modes (ROSE-ILS, -VOR, NAV, ARC, PLAN) and ranges.
  • Baro setting.

Usage

Barometer Reference Display Window

  • Barometer Range: 745 hPa to 1100 hPa.

Barometer Reference Selector

  • Outer ring selector:

    • Allows switching of the barometer reference to either hectoPascals or inches of mercury.

    Note: Unit selection does not appear on the PFD.

  • Inner knob selector:

    • Allows manipulation of the value displayed in the barometer reference window and on the PFD (visible below the altitude scale). When the FCU is initialized, it will display 1013 or 29.92 based on the outer ring selection.

  • Pulling the knob selects the standard baro reference setting. The display window and PFD both will show "STD."

    • When in STD position pushing the knob makes the last selected QFE or QNH setting available.
    • When pushing the knob after switching from STD position, it will change between ONH to OFE based on current selection. The display window will note QFE or QNH.

  • Note: The QFE selection is a program installed on both the FMGC and GPWS computers. It allows for each computer to use the selected program independently of the barometer reference selected through the EFIS control panel.
