Super thread. Exactly what I tried to start a couple of days ago.
Some eight seconds later the thrust reduced on the left engine to a similar level.
It's that
"to a similar level" that worries me. If we are looking for ice / wax etc., just what are the chances that there would be any similarity in a fault -- causing a specific reduction -- that was spread in time by 8 seconds?
This sounds horribly like a set of parameters being met that cause such a specific instruction.
