The manufacturers have little say in how their customers apply that technology to training - all they can provide is guidance on how their product is operated. The technology in and of itself is nothing more than a tool. It was not intended to sideline or replace the human pilot, it was intended to assist them.
Spoken like a true Techy guy Dozy, manufacturers have an ENORMOUS amount of influence with respect to regulators and operators.
If the airlines have decided to use technological advances as an excuse to cut back on training costs to the extent that safety has been affected, then the onus is on them to correct it. If the industry wants to continue to expand to the point where automation is mandatory in certain types of airspace, then they must increase hands-on training for when the fit hits the shan to make up for it. If a plurality of pilots feel that the technology has been misused by the airlines in such a fashion, then they should band together and do something about it.
Again Dozy, easy to say, and rather nieve.
Firstly, airlines have been sold a concept that more automated and envelope protected aircraft are inherently safer, which based on past experience is statistically correct, the trouble is it has created a raft of other issues, some of which include a continual erosion of piloting skills and organisationally a loss of respect in the profession as well as a new set of complex unforseen failure modes that overly clever designers and systems engineers never even contemplated.....after all the technology is so advanced and aeroplanes can fly themselves don't they?
You can inform us as eloquently as you like regarding the logic and inherent redundancies built into a system..but the fact remains that aviation is still the cruel mistress when things go wrong....just as it was recently where on a final vector to the ILS at our destination with the A/P engaged we flew through a localised area of turbulence that was powerful enough to roll the aircraft to 30 AOB and disconnect the A/P....pilot intervention prevented any further roll deviation and a departure towards the terrain 2000ft below us.
