Air Data Computer failure
What are the certification criteria for an ADC system when it is failing?
For instance if you have an ADC that has an internal problem and is producing erroneous data ,is there any requirement for the aircraft architecture to remove this data so that it does not affect other systems and for the ADC to produce a failure warning or crew alert.?
If the faulty ADC is replaced with data from a working ADC should not the faulty data be no longer available to other systems on the aircraft so that unnecessary system failures are not induced?
