My only aviation experience is as a passenger.
Having said that...
I thought modern jets had old-time pneumatic (air tube) pitots in addition to the new-fangled electronic ones, as backup.
The idea was (I thought) to always have a set of the most basic instruments as a backup using the oldest and known reliable mechanical technologies.
Is that wrong?
They do. That’s why things often turn out to be a little more complex than armchair observers on the internet think.
