Multifunction Display (Mfd) - Beechcraft Baron G58 Pilot Operating Handbook

Section 7
Model G58 Systems Description
The PFD incorporates controls for communications, naviga-
tion, altimeter control, and Flight Management System func-
tions. Trend vectors are shown on the airspeed and altimeter
displays as a magenta line which predicts the airspeed or alti-
tude 6 seconds in the future assuming the current rate of
change is maintained. The turn rate indicator also functions as
a trend indicator on the compass scale. The PFD can be dis-
played in a composite format for emergency use by pressing
the DISPLAY BACKUP button on the audio panel. In the com-
posite mode, the full crew alerting function is retained, but no
map functions are available. When L BAT is turned on or exter-
nal power is supplied to the airplane, a reduced subset of the
G1000 system will power up including the PFD operating in
composite mode. This will allow the pilot to monitor engine and
electrical status prior to and during engine start. The PFD is
powered by Left Bus and is protected by a circuit breaker,
placarded PFD, located on the avionics circuit breaker panel.

MULTIFUNCTION DISPLAY (MFD)

The Multi-Function Display (MFD) is a 10.4 inch Liquid Crystal
Display (LCD) referred to by Garmin as a Garmin Display Unit
(GDU) 1043/1045. It displays engine data, maps, terrain, traffic
and topography displays, and flight planning and progress
information. It also controls and displays weather data link
information, lighting strike information, and audio entertain-
ment features. The display unit is identical to the PFD and con-
tains the same controls plus the addition of autopilot controls.
Discrete engine sensor information is processed by the Gar-
min Engine/Airframe (GEA 1 and 2) sub-system. When an
engine sensor indicates a value outside the normal operating
range, the legend on the MFD will turn yellow for caution
range, and red for the warning range. The legend will also
flash when the warning range is activated. If the pilot is on a
page other than the primary engine indication page when an
engine parameter is exceeded, the primary engine page will
