Today I finished my sim proficiency check
and did the experiment.
We had ECAM messages as below
ENG 1(2) START FAULT
THRUST LEVER NOT AT IDLE
THRUST LEVER----------IDLE
We disregarded thiis message, left the thrust above idle.
the engine continued start automatically until stabilized.
Then the ECAM message disappeared, the next monent
the thrust increased to the thrust position.
Conclusion: Always always check the thrust levers are at idle
when you start engines.
