Takata said (post 2219)
I don't fully understand why Goodrich would say that the pitot probes are also sending data for the cabin pressure controler (and for engine monitoring) when I understand that such system would use the static pressure instead of the total pressure in order to control the pressurisation (Cabin delta P). Moreover, the pressurization schematic is pointing ADIR 1+2+3 for the controler data.
It looks like each pitot probe is coupled with two static ports, then if the pitot probe is faulty, the static ports' data are considered faulty also?
Or, not only the pitot probes were frozen but also the static ports?
In fact, if the static ports were considered faulty, all of the sequence would make much more sense. In the Air Caraibes case, the sequence starts with the TAT probes freezing before the AIS, Altitude, ADRs went nuts.
For a possible explanation/resolution of the confusion about static pressure sourcing, see this post by OVERTALK:
