Fully autonomous cars have been the ‘tech’ promise for the last 20 years, always saying ‘autonomous vehicles will be here in 10 years’. I’m still waiting. Autonomous vehicles will be here…..eventually…..2050 for a full autonomous vehicle I reckon. Autonomous heavy jet ops………another 50 years at least. Main stream quantum computing or a real AI able to actually make a decision will be needed first, not just a coded response to an inflight situation. As mentioned, auto land has been around for a while yet even that is still a two person operation. Not really up on the small/ business jet ops, but IIRC the only single pilot light jet ops are wee little fellas up to about 5-8 seats….just my two cents worth..
