What is the difference between a cyan ALT or an amber ALT displayed on PFD? |
Cyan: BARO reference miscompare between pilot amd copilot side. This can be done intentionally (FL/ALT) Amber: A miscompare between Altimeters is detected. |

|
Explain the 2 ADS |
Provide BARO IAS VS OAT Vne presented on the PFD’s and used by AFCS, AHRS, FMS, WX and TCAS. Consist of 2 Pitot static probes 2 ADM 2 OAT 2 Alternate static sources |
|
|
Describe the Pitot system |
One total pressure port, 2 static pressure ports and electrical heating. |
|
|
How are the standby instruments fed by pitot? |
The Copilot side provides direct data to the pilot side |
|
|
Describe the ADM |
It converts static and dynamic pressure into digital signals used by the MAU. |
|
|
Explain the AHRS |
Attitude and Heading Reference System. Consists of the AHRU, Fluxvalve and AHRS control panel. The AHRU is a strapdown assembly of 3 FOGs and accelerometers. Each AHRU powers 28VDC to its own Fluxvalve ADS and GPS inputs enhance the AHRS |
