Now that all this discussion about Thrust Modes is up, how are you guys dealing with that bulletin regarding "eec software updates" that change the spool up/down time while at high altitudes ?
Here, is almost that a "common" SOP, to always select CON after reaching the cruise altitude.
Nevertheless, the bulletin says that this is only ONE of the methods that could help in case you get yourself trapped in such scenario (looooooong time to have an engine response after thrust decreased under 60% N1 etc etc).
