2.3. Display
The PFD replaces the existing Attitude Indicator and DG in the center of the primary
ight instrument cluster. Like the instruments it replaces, the top half presents an
Attitude Display and the bottom half contains a Navigation Display (Figure2-26).
Between the two halves is the Data Bar. The Data Bar contains a dedicated display of
real-time winds, Outside Air Temperature (OAT), True Airspeed (TAS), and GPS Ground
Speed (GS).

Unlike the mechanical indicators it typically replaces, PFD can also display all the data
provided by the remaining four instruments in the six pack (airspeed, altitude, turn and
slip, and vertical speed), and much more. Concentrating all primary ight information
onto a single instrument directly in front of the pilot improves instrument scan and
reduces pilot workload, thereby enhancing safety, especially in busy phases of ight.
Additionally, analog backup instruments can be retained in the pilot’s primary eld
of view, and should be included in the instrument scan to cross-check indications of
both the primary (EFIS) and backup (analog) instruments.
