AFS computer redundancy
•Fail Operational capabilityFor precision approach, as soon as second AP engaged, if the active system fails, the second system takes over automatically
•Each computer consists of two independent processing channel (CMD and Monitor)
•Fail Passive capabilityIn case of disagreement between the two channels, the affected function or computer is disabled before it may affect A/C guidance

•Alpha-floor function is active above 100 ft. provided ATS is armed.
•FAC detects a too high AOA it send the signal to TCC to engage in Thrust Latch (THR L).
Alpha-Floor Protection
AOA minimum value which causes THR L engaged depends on F/S lever position:
-7° in clean configuration
-12° in 15°/0 °, 15°/15° and 15°/20° configurations
-11° in 30°/40° configuration

If the aircraft AOA exceeds a given value, ATS thrust latch modeengages in order to automatically apply thrust limit (THR limit) as selected on the TRP to ATS (except THR mode is already engaged)
The activation of α-floor protection is not accompanied by an AP/FD nose down order(the engaged AP/FD vertical mode remains engaged with the associated pitch command)
