Can somebody please explain how the MCAS system can cause an unreliable airspeed indication after takeoff?
I still don’t understand why a blocked pitot isn’t even being discussed.
It’s my understanding that this was a morning flight (local time).
Could the pitot covers have been left on, or possibly a mud wasp got in there overnight?
At the end of the day, if the engines and the hydraulics were working, why weren’t two qualified pilots able to “fly” the aeroplane in apparently fine weather back to Addis Ababa?
I’m honestly confused as to why everybody seems to be jumping on the MCAS bandwagon!
