I have been flying long enough to have several books thrown at me, currently the queue is quite short you shouldn’t have to wait.
Why is it then that when we see the FMA on a managed descent change from MACH or SPEED to THR IDLE, sometimes we do not see a corresponding change to the E/WD display to IDLE?
On some occasions when I have not seen the E/WD change to IDLE as described above on a managed descent, I pull OPN DES and then see the E/WD display IDLE. There must be something else going on here.
