May some old bones be allowed to comment? Yes, modern technology is a wonderful tool; but it is just that; a TOOL. It is not the master. Way back in antediluvian times my airline had some good kit for the era. However, when it all went t.u. there was no argument about disconnecting the lot, turning it into a big Cessna single and FLYING THE AEROPLANE. Once sorted, work out what went wrong and reinstate the automatics as appropriate. Remember, the best computer on the aeroplane is THE PILOT'S BRAIN, and the best safety device is THE PILOT'S SENSE OF SELF-PRESERVATION.
Thanks for listening "Nurse, is it time for that nice medicine again?"
