MFD
1 - STATIC AIR TEMPERATURE (SAT) INDICATION
− The SAT is presented as a digital readout in degrees Celsius.
− Colors:
− Digits: green
− Labels: white
− Ranges from –99 to +99°C with a resolution of 1°C.
− In the event of ADC failure or invalid SAT, the digits are
replaced by three amber dashes.
2 - TOTAL AIR TEMPERATURE (TAT) INDICATION
− The TAT is presented as a digital readout in degrees Celsius.
− Colors:
− Digits: green
− Labels: white
− Ranges from –99 to +99°C with a resolution of 1°C.
− In the event of ADC failure or invalid TAT, the digits are replaced
by three amber dashes.
3 - TRUE AIRSPEED (TAS) INDICATION
− The TAS is presented as a digital readout in knots.
− Colors:
− Digits: green
− Labels: white
− Ranges from 0 to 999 kts with a resolution of 1 kt.
− In the event of ADC failure or invalid TAS, the digits are
replaced by three amber dashes.
PFD
1 - AIR DATA SOURCE ANNUNCIATION
− Label: ADC1 or ADC2.
− Color: amber when only one ADC is supplying both sides or
each ADC is supplying opposite side systems (ADC or SG
pressed on the Reversionary Panel - refer to section 2-4, Crew
Awareness).
− Annunciation is removed when each ADC is supplying the
respective side systems (ADC 1 supplying captain’s side and
ADC 2 supplying copilot’s side).
