* - and it is VERY embarrassing to be flying in selected speed on the ILS and having forgotten to activate the approach, you then push for managed speed at about 5 miles, only to have the A/THR put in a shed-load of power to get you back to 250kts !!!
I know exactly what you mean, I did it during my line training with the Head of the Training Department in the left seat. I looked at him expecting him to tell me what to do, he just looked back with a "What are you looking at me for ?" expression on his face.
I was rewarded with some extra sectors.
With over 8000hrs on the bus since then I've never done it again.
