Hello PJ2;
Thank you for pointing out that I was mistaken when I referred to the memory items. I regret that I didn't think a bit longer before writing that quick reply to A33Zab's post.
Of course one would hope that after AF447 no flight crew will ever be as ill-prepared for an UAS situation at cruise level. But, if I may rephrase my original question - would it help prevent future accidents if sophisticated Flight Guidance and Aircraft Monitoring systems, having rejected three sources of airspeed information as unreliable, and 'knowing' conditions such as configuration, weight and altitude, provide more specific information as to the appropriate response?
