_______________________________________________________________
1. General_______ The aircraft is equipped with three Air Data/Inertial Reference Units (ADIRUs). Each ADIRU receives data from the four types of sensors after:
-three pitot probes which provide total pressure data,
-six static probes which provide static pressure data,
-two Total Air Temperature (TAT) sensors which provide air temperature data,
-three Angle Of Attack (AOA) sensors which provide angle of attack data of
the aircraft. The TAT sensors and the angle of attack sensors are directly connected to the ADIRUs. The pitot probes and the static probes are connected to eight Air Data Modules (ADM) which convert pressure data before they send them to the ADIRUs. The sensors, the probes, the ADMs and the ADIRUs are power supplied as follows:
-------------------------------------------| EQUIPMENT | 28VDC | 115VAC | 26VAC | -------------------------------------------| ADIRU | X | X | X | |----------------|-------|--------|-------| | AOA Sensor | | X | X | |----------------|-------|--------|-------| | PITOT Probe | | X | | |----------------|-------|--------|-------| | TAT Sensor | | X | | |----------------|-------|--------|-------| | STATIC Probe | X | | | |----------------|-------|--------|-------| | ADM |13.5VAC from ADIRU | -------------------------------------------
In normal configuration, the Captain Primary Flight Display (PFD) and
Navigation Display (ND) show the data computed by the ADIRU 1.
The First Officer PFD and ND show the data computed by the ADIRU 2.
The data from the ADIRU 3 can be displayed by action on the AIR DATA
selector switch or on the ATT HDG selector switch located on the SWITCHING
panel.
These selector switches which define a priority order for the ADIRUs are
also used by several other aircraft systems (Ref. Para. 4.F.).
