It seems almost ridiculous the fact the aviation industry is still today using sub heated Pitot's.
A very simple device, so important, an essential input to the A/C complex IT Systems, seems to be not advancing to a "changing environment".
And clearly, the trigger of a serious accident where the System and the crew were not capable to deal with the consequences of it's VERY BRIEF failure in presenting consistent output.
Another almost ridiculous fact was a DESIGN FLAW that allowed Garbage In generate Garbage Out
affecting an essential System output, the aural Stall alarm. An essential input to a crew facing an unprecedented situation.
This first issue IMO should be addressed earlier by Airbus SAS and the patent filed (of a l@ser based sensor) shows a tentative to face the problem.
And the 30+ UAS incidents shows the (previous) vulnerability.
