Re: Turkish Airlines Flight 1951
'That's not correct, most landings are done manually.'
The landings that are done manually have all the complicated systems, the ones you seem not to trust, turned on to help the pilot fly the aircraft smoothly, having them do it fully manually would be far more dangerous. Notwithstanding the pilots having to make 4 manual landings in 90 days to keep their licence current, the auto-land is consistently better at capturing the localiser and glide-slope and maintaining it all the way to touchdown. On long haul that does mean most of the landings are 'manual' as they barely make enough flights to stay current, on short haul I believe some airlines actually forbid manual landings unless required for currency as humans are less efficient at it.
'Also, take into account that pilots are blamed, even when it's blatantly obvious that it's the precious autopilot who crashed the plane.'
No, you're going to have to provide some actual proof for that, maybe a link to a few accident reports where you can prove the pilots were unfairly blamed. Otherwise you're going down the conspiracy theory route of saying you can't trust the evidence because that's what 'they' want you to think.
It's worth noting, when I say the historic accident record I mean the fact accident numbers are at an all time low, even before you normalise for the increased rate of flying it has never been safer to sit in a commercial airliner irrespective of how it's flown. For example there were no passenger jet crashes in 2017, beating the previous year which was already a historic low.
So even if all the recent accidents have been due to the autopilot it's still safer than it was a few decades ago when there was more human interaction and less people were flying.
