Uplinker, shared reality;
The human contribution in safety approaches its limit; best to focus on maintaining the current level with training.
Humans cannot be considered as machines; not every training scenario can be foreseen or practiced, and that which is, can never guarantee to have well rested, well trained pilots with reliably memory, requisite situation assessment, and decision making.
Who pays; operators have difficulty in balancing current training budgets, increases unlikely to be passed on to the customer.
For technical solitions, manufactures should be able to absorb some cost, if there are advantages from reduced cost of operation, particularly with new aircraft - more sales. Similarly operators with reduced operating cost.
There are two distinctly separate concepts:- single pilot throughout the flight for commercial operations is distant, requiring new designs and certification standards.
Limited single pilot operations should be feasible with today's technology and certification; proof of concept required - AI & operators.
The certification of modern aircraft includes single pilot operation in considering incapacitation - continued flight and landing.
Thence as per slast.
Defeatist hypothetical scenarios are easy to imagine, but first assess these against certification requirements which are probability based; a realisation that not everything can be avoided or managed, but that which is, provides an acceptable level of safety in an uncertain world. Any new concept has to heed this.
A better understanding of the issues could be gained by considering how these new concepts can be achieved; how can systems be designed, tested, and certificated. Use the expertise of current operations and pilots to solve problems, not create flimsy barriers to inevitable progress.
