PRIMARY FLIGHT DISPLAY (PFD)

The PFD is an integrated display of essential flight information. The
PFD is divided into functional groups, shown in Figure 3–19, that are
described below.
D
Mode Annunciators – The PFD displays mode annunciators from
the flight guidance system, PFD source selection, and comparison
monitor functions.
D
ADI Display – The ADI symbols use a truncated sphere format to
display standard attitude information. The attitude display receives
its inputs from the AHRS. The ADI also displays radio altitude,
marker beacon, and states of operation.
When either the pitch or roll data is invalid, all scale markings are
removed, the attitude sphere turns cyan, and
at the top center of the sphere.
D
Air Data Displays – The PFD airspeed, altitude, and vertical speed
displays receive inputs from the MADC. A standard slip–skid
indicator is on the PFD bezel controller.
