Introduction
The Primary Flight Displays (PFDs) present a dynamic color display of all the
parameters necessary for flight path control. The displays provide the following
information:
The PFD consists of two general areas, the sky/ground attitude indicator and the
compass/backup mini-MAP. The AUX Display is located outboard of each PFD.
When the Display Select Switches are in the OUTBD or INBD positions the PFD
and AUX Display are shown in a half screen format. In this configuration, the
compass remains as a compass and does not become a backup mini-map.
Failure flags are displayed for airplane system failures. Displayed information is
blanked or replaced by dashes if no valid information is available to the display
system (because of out–of–range or malfunctioning navigation aids). Failure flags
are displayed when aircraft systems cannot generate a reliable display.
Flight mode annunciations are described in Chapter 4, Automatic Flight.
Airspeed
Airspeed is displayed on a tape and in a digital window on the left side of the PFD.
The current Mach number is digitally displayed below the airspeed tape when the
current Mach number is 0.40 Mach or above. A groundspeed readout is displayed
in the upper left corner of the compass/backup mini-MAP. An airspeed trend
vector indicates predicted airspeed in 10 seconds. Selected airspeed is displayed
above the airspeed tape.
Takeoff and landing reference speeds and flap maneuvering speeds are shown
along the right edge of the airspeed tape. Maximum and minimum airspeeds are
also displayed along the right edge of the airspeed tape.
Attitude
The attitude indication displays the airplane pitch and roll attitude referenced to
the horizon.
