Weather that creates EGPWS warnings through the rad alt ( had it)
AOA vanes being blown by a stiff breeze on the ground creating stick shaker while lining up ( had it)
Cabin temperature reading 22 degrees when in fact it was over 30 and climbing, no other indications apart from pax getting very upset ( had it)
You’d have to start from scratch with all these system designs because they all rely on the pilot intervening if they go wrong. Starting from scratch will be very expensive.
Can you imagine if the weather forecasters get it wrong and all jets for capitol city A divert to Alternate B because that’s the only place they have enough gas for? With no Captain who is going to say six hours earlier at the pre flight stage “ nah actually we’ll put on another tonne cause I’m not sure the forecasters have got this right”? Certainly not the earth bound ‘dispatcher’. I’ve seen that too and people were parking aircraft on grass to get jets off the runway for fuel critical airborne aircraft.
I would bet that it won’t happen in my children’s lifetime.
