Sub heated AS probes and GIGO*

Hi,

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 LASER based sensor) shows a tentative to face the problem.

And the 30+ UAS incidents shows the (previous) vulnerability.

GIGO

(*) "Garbage" generated in the design
