The additional means for "testing for a plugged pitot" is so trivial I won't even suggest (one of about 10 obvious ways) - simple enough even for a digital device to deal with. Not 'pilot error'; stupid fucking Design Error from the get-go.
And this chestnut is especially inexcusable because: EVERYONE KNOWS how easy it *could* be plugged, visibly OR virtually undetectable, except by a lo-pressure CHECK. Add one decision block to flow-chart:
Pitot tube: [blocked] [unblocked]
-- with logic to be sure and tell Captain >WHICH mode< the silicon is banking on, just now. <<< Hell, make it audio; purred a la Santa Baby.
Now we're fucking FLYING via Redmond-grade dumbth!
