inches of mercury.
Note: The unit selected does not appear on the PFD.
b. Inner knob : For selection of the reference value displayed in the barometer reference
display window and on the PFD below the altitude scale.
At FCU initialization, the window displays or 29.92, depending on the unit selected.
• Pulling the knob selects the standard baro reference setting. The PFD then displays
“STD.” (Rotating the knob has no effect.)
• Pushing the knob from the STD position makes the last selected QFE or QNH baro
setting displayed.
• Pushing the knob again changes from QNH to QFE or vice versa.
The window displays “QNH” or “QFE” according to the pilot selection.

selected pin program (QNH or QFE), independently of the baro reference setting
selected on the EFIS CTL panel.
