SID and Pieced8, let's not forget the basic airmanship process of fuel endurance at the start of the sortie, THE FLIGHT TIME UNDERTAKEN, the pumps being inappropriately managed, followed by multiple warnings acknowledged and cancelled by the pilot leading ultimately to a poorly executed auto EOL.
if we should learn anything it is this:
Knowledge is power! The power to act correctly! Knowledge that despite any contents indications to the contrary, a fuel backstop WARNING, independent and robust, should be taken at face value as described in the RFM procedures. Thinking one knows better, acting on hearsay or past experience, does not cut it. Knowledge, training and discipline. These are the three things that stand out to me as the key learning points.
Alternatively we can immerse ourselves in multiple conspiracy theories and learn nothing!
