Time to look to see if the same supplier provided pitot tubes to Boeing.
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?
ours or theirs?
Did Mujibur put gum on the static port thinking that he was plugging a hole?
Every competent pilot I know knows a pitch/power relationship for climb and cruise speeds. And if the airspeed indicator does not match what they know is a normal relationship between what the indicator says and what they have for pitch/power, they rely on experience.
I had an airpseed malfunction on a T-38 years ago, and landed it quite safely and easily by relying on that relationship. (And the white rocket will eat your shorts in a moment if you ever let the airspeed sink below what is recommended.)
My 5.5 years in aircraft instrumentation knows that most airspeed indication problems are caused by the pitot tube heater not working. But this was in a warm climate and I don’t think they got very high where the air would be cold, so maybe not in this case.
Lord I hope the pitot tube was not the root cause. These days, you can easily back up your instruments with GPS to get a 2nd opinion on air speed, altitude, and heading. Radar would be yet a 3rd source.
If the airspeed indicator survived then it will be used in another jet.....
