Can anyone tell me at what point the EECs go from approach to intermediate or minimum idle as all my FCOM says is "after touchdown"? If the engines had gone to a lower idle the difficulty could be greatly exacerbated.
It's standard Boeing design practice to hold the engines at approach idle for 5 seconds after the air/ground transition, although the specific implementation varies with the different aircraft models. The older aircraft (e.g. 747-400 and 767) do it with time delay relays, newer models do it in software.
