Less rare than simultaneous (including rate) obstruction of three Pitot Heads?
Fair question. However, I am basing my question on the FCOM. It's in there.
We are dealing here with most likely an extremely rare confluence of bad things. Yet I witness an unusual presence of "stuckness" and "dismissiveness". I'm not actually taking sides 3hl. What I seek to do is express my thoughts regarding possibilities.
Here, your statement is best directed at Airbus/AirFrance. Again, it's in the FCOM as a cause of duff speeds.
