Fuel-Off
Good post. But not everything is lost if, as you demonstrate.
It does not need old equipment to get more proficient. It only takes a look through the magenta/FD. Take the last incident down in India ....
What has been demonstrated is being lost if something shows an unexpected and apparently wrong turn and a desperate attempt to regain the FDs quickly, with a wrong switching and then a religiously following of the two bars almost leading to a stall.
When the magenta does not look right, pick a pitch and heading, check power and fly the big jet like a Cessna (or for that matter a MFS). Let your buddy sort out the electronics and then continue.
It's not rocket science and there's no excuse to stall things with magenta lines.
Pitch, heading and power are and were the same on a Cessna, Caravelle and in a 787/350.
And both will stall if pulling too much for too long!
Your attitude is good start!
