Skyranger,
There were Amber captions for Tx Pumps - because they were switched off - and Prime pumps - because they were switched on. The Amber Fuel caption, (there is only one), is operated as a mathematical sum of total fuel remaining and comes on circa 70 - 75 kgs total fuel. (How much did the AAIB find?).
There was no attempt at a restart - in order to carry out a restart in flight, the engine main switch has to be moved to "Off", which entails opening both guards.
Even if the guards were both opened and the switch moved to "Off" and then to "flight", the engine will not restart until N1 has reduced to below 17%.
(Where did the AAIB find the ENG Main Switches)?
