Colour Philosophy
To facilitate the reading of information in the integrated avionics system, a colour
code has been defined. This colour code applies to all displays and readouts on the
MFDs in both FWD and AFT cockpits.
The colour code aims to alert the pilots of conditions requiring either attention or
immediate action. It helps the pilots in their operations, as the colour code makes
obvious what input or selection is possible or not, and highlights specific
information in abnormal conditions.
WARNING ALERTS
Red is associated with the indication of hazardous conditions that require
immediate pilot attention and may require immediate pilot action such as: error,
failure, malfunction, or danger. Red is also relevant to out-of-range conditions.
CAUTION ALERTS
Amber is used to indicate marginal conditions or to alert of situations where timely
pilot intervention or action is required. These situations include failures, out-of-
range data, indications trend, invalid data, and traffic alerts.
SELECTION, DATA ENTRY, DEFAULT SETTING, AND PAGE CHANGE
Green colour is used to identify the symbols enabling the selection, data entry, page
change capabilities, and setting default data.
Cyan colour is used to identify the FMS-generated pages and the selection
capability of the FMS-generated pages.
COLOR-CODING OF MFD INDICATORS
For the integrated avionics system, the color-coding uses Orange, Amber, Cyan,
Green, Magenta, and White.
Orange is used to identify the Ground Track Pointer on the compass rose.
Orange is used to identify advisory navigation information (DME Hold active)
and when flying over a middle marker beacon.
Cyan is used to identify flying over an outer marker beacon, bearing pointer
#2, and associated navigation source information.
Green is used to identify bearing pointer #1 and associated navigation source
information, and condition messages when FMS is the active navigation
source (OFS, NPA, and EXEC).
