I only know of one situation as documented in FCTM, that is in an early descent. What else can you guys think of?
It was earlier stated that there will be IDLE with VNAV SPD but that is not always the case. When doing an enroute descent during cruise flight, you get THR/VNAV SPD and the thrust levers have a partial reduction in power.

Not sure if there is some sort of variation in the amount of thrust reduction based on the amount of descent required which there apparently is with FLCH. Anybody know?
