B. Multi-Function Display (MFD)
The MFD is a 10.4 in liquid crystal display. Bezels on the left and right side of the MFD have the
%
controls for the ICS. The lower edge of the MFD has ‘softkeys’. The function of the soft keys relates
%
to the on-screen display and if a key has a function related to the current display the display will
%
show the function of the key.
%
The MFD displays engine and airplane pages on the left slide of the screen. The remainder of the
%
screen is used to display navigational pages. The bezels on the left and right side of the MFD have
%
the same controls and function as the bezels on the PFD. The left side bezel on the MFD has also
%
the controls for the autopilot system. Refer to Chapter 22 for more information about the autopilot.
%
The Engine instrumentation system window (EIS) is on the left side of the MFD and displays a full-
%
time dedicated display of engine parameters. The information is presented in three displays:
%
)
Engine Display. This is the default display and shows following critical engine and fuel
%
indicators:
%
)
Engine load. The engine loads are displayed as a percentage. Pointers on each side of a
%
vertical scale move to show the engine load. If the system fails the display shows a red or
%
yellow cross to the left or right of the load indicator to show which engine system has failed.
%
)
Engine RPM. Pointers on each side of a vertical scale move to show the engine rpm. If the
%
system fails the display shows a red or yellow cross to the left or right of the RPM indicator
%
to show which engine system has failed.
%
)
Fuel flow. Small windows to the left and right of a GPH marking show the engine fuel flow
%
digitally. If the system fails a red or yellow cross is displayed in place of the digital indication
%
for the failed system(s).
%
)
Oil temperature. Pointers above and below a range bar indicate the oil temperature. The
%
range bar is color coded, green to show the normal operating range, yellow in the cautionary
%
range and red in the warning range. The pointers move from left to right to indicate the oil
%
temperature. The pointer above the range bar indicates the oil temperature of the left engine
%
and the pointer below the range bar indicates the oil temperature of the right engine. If the
%
system fails a red or yellow cross is displayed above or below the range bar to show which
%
engine system has failed.
%
)
Oil pressure. Pointers above and below a range bar indicate the oil pressure. The range bar
%
is color coded, green to show the normal operating range, yellow in the cautionary range and
%
red in the warning range. The pointers move from left to right to indicate the oil pressure. The
%
pointer above the range bar indicates the oil pressure of the left engine and the pointer below
%
the range bar indicates the oil pressure of the right engine. If the system fails a red or yellow
%
cross is displayed above or below the range bar to show which engine system has failed.
