Suplus1, Will and PT2
All thanks for superb, thoughtful, balanced and insightful efforts throughout the course of this extended discussion. Your comments and insights are deeply appreciated by this aerospace engineer who worries about your and your passenger's safety daily and who greatly values and welcomes your highly experienced and most valuable commentaries and discussions at all times. I rely on wise mentors in the aviation community to guide we engineers and hopefully helps us avoid the traps of hubris, over reliance upon automation, overly complex systems, which lead to tempting and allowing airlines to cut corners on costs and training. Such design and system approaches dangerously and imprudently lead some airlines and training schools to advocate that pilots become system monitors rather than skilled airman. There are many questions and ongoing concerns regarding training, airmanship and safety, backup instrumentation and systems design and we engineers ignore your advice, guidance and wise counsel at our peril. Thank you all.
