------------------------------------------------| Parameter | Threshold | |----------------------------------------------|
| Total pressure | 5 hPa |
| Averaged static pressure | 5 hPa |
| Left static pressure | 2 hPa |
| Right static pressure | 2 hPa |
| Angle-of-attack | 4. |
| Total air temperature | 3.C |
------------------------------------------------Table 1 : Comparison Thresholds
The messages resulting from a miscompare between parameters point the faulty sensor if it can be identified (one data differs from the two others which are identical) or the sensors which disagree. They are sent to the CFDIU in normal mode through label 356 of the ADR output and can be accessed by "Class 3 Faults" page on the MCDU menu.

B. Interactive Function
(1) General The interactive mode is activated via the SYSTEM REPORT/TEST page ATA 34 chapter (Navigation) including Air Data and Inertial Reference System (ADIRS). As this system includes two parts (Air Data Reference and Inertial Reference), two interactive functions are available :
(a) ADR interactive function : select NAV from the SYSTEM REPORT/TEST page and then the selected ADR (1 to 3) to activate the ADR interactive mode and display the main menu (Ref. Fig. 032)
