HI
interresting proposition..question is ..is it feasible for say,three or four-engined aircraft?..and the possible argument from aircraft manufacturers..that the rate of occurence might not justify the additional cost of engineering...that the new set up will have it own set of what might go wrong...mistakes will always happen as long as the human factor is present
And the ready accusation of over-engineering everything.
Now from what i understand that we are looking for a device that will prevent an engine(s) thrust levers from beign advanced if an other engine(s) thrust lever(s) is in the reverse thrust mode..wouldn't this come with its own set of dangers?
Am rambling here..but just my thoughts on the subject for what its worth
