With respect:
This is a mainly a pilots forum and not so much an "engineering" forum. Your quote relating to the "level of ignorance of certification requirements" may have been construed to mean "engineers have no idea how critical pilots deal with required certifications during line operations", so this may also be true that engineers are also "a disturbing ignorance" to line pilots in general. Pilots fly, engineers do what they do!
Yes, the engineers are by and large somewhat ignorant of what pilots do. However for the most part we know better than to go on a public form and overtly criticize what the pilots are doing based on that ignorance. Many posters - alleged pilots, although in some cases I have my doubts - on this form have no such qualms regarding what the engineers do.
