This has been a big subject of discussion in our office since they debuted it at Farnborough. The patent is fascinating but the presentation was light on flight test/certification milestones.
I am not involved in anything Embraer but it’s a a v innovative step, kudos to them. I would imagine for the likes of London City or places like Innsbruck some big performance boosts available but certification will be a a nightmare. Given autoland has an easy contingency case (go around) by comparison I can see some big headaches.
edited to add - thank you for the patent as it’s the most detail I’ve seen on the subject.
They will have to demonstrate to the regulator that the probability of failure is low enough and the system robust enough to deal with all the potential failure cases and meet the required performance if they are sharp pencilling down to Perf A min margins which having done some (sim only) testing of engine out procedures at real performance limiting cases are pretty eye opening even with margins sufficient for my very average pilot techniques.
