How many crews have long forgotten the lessons from the B-757 tragedy in Cali, Columbia about 12 years ago, and others, or close calls in B-737s, A-320s etc? Four shiny, brand-new stripes are no protection. Neither are four old, faded stripes and an encyclopedic knowledge of theory and procedures, required by some foreign agencies.
Automation should never be trusted to keep you and your passengers alive, or even comfortable, whether with or without awareness of speedbrake extension in almost every descent, EGPWS, altitude warnings etc. Read up on what the Factory Test Pilot tried with the brand-new widebody aircraft at the factory airport. It is not difficult to find. Some automated aircraft are described by many experienced pilots as "having quirks", no matter how basic or advanced the automation. The more modes available, the higher probability that a new situation in mountains/IMC can set a trap? The CIVET into LAX at 230 knots with 3 runway changes can be bad enough.
As an observing brand-new Instructor Pilot commented about seven years ago during our Initial Training, when we discussed the need not to hurry anything: "Speed Kills". A mission-oriented mindset can quickly override the focus on safety.
'Tex', I hope you have a nice retirement.
