Hi,
DW
I see no systems weakness in the design other than the pitot tubes
And this is the biggest weakness you can found on the modern planes who are using computers and automated flight systems
This is one of the most important source of data for the automation system
Another failure of testing and certification process .... and so another invite to disaster
For a Curtiss Jenny .. a pitot tube clogged was not a very important problem ... for a Airbus or other brand using automation .. it's a crucial data loss
