The post above by ACLS65 about Goodrich Sensor System 0851HL Pitot Probe is describing in short the the Pitot functions in the second page; the end of it is interesting to draw a direct link between the pitot's failure and the cabin vertical speed control also. Then, the advisory (no warning, no check list) at 2014Z might be also linked to the unreliable Air data provided by the pitots as Thales and Goodrich probes are interchangeable.
The 0851HL pitot is also functionally
interchangeable with existing pitot probes certified on
A318/319/320/321/330/340 manufactured by Goodrich
competitors.
DESCRIPTION
Sensor Systems Model 0851HL Pitot Probe is an integral
part of the Air Data System of the aircraft. Sensor Systems
pitot probes provide vital information for aircraft flight
control. Pitot pressure measurements are used for
calculating flight parameters, which include pressure
altitude, airspeed and Mach number. Air data probes also
provide information for secondary purposes such as
engine control and cabin pressure differential.
