Dealing with Pitot data, sometimes unreliable

Hi,

This happens over a period of time, as you say, and since in solid state, the water has slower Thermodynamic behaviour, lengthening the event?

I am assuming that most of Pitot discrepancies (among the 3) takes some time to stabilize in a condition capable to trigger a "switch law".

I am just imagining as "technically feasible" an EW resource that could warn the crew, before a major System change, any discrepancy and itīs rate of unstabilities, i.e. characterizing the differences between the (odd) number of AS sensors.

I consider an almost "useless" redundancy (for cruise level) the 3 identical Pitotīs and capable to trigger a "law switch". Doing that, (scanning and processing the 3) the System is almost like "amplifying" the Pitot problem.

Certainly Airbus SAS is working in better processing the info presented by current available Pitot, data. And also doing R&D on this issue. The Laser AS sensor filed patent by them shows it.
