Framer et al
There is an assumption we all, or most of us anyway, make is for consistency.
When we changed from reduced power to detent in the Q400, it took a little while for the system to adapt, including the drivers with the new jet like speed we had all been promised.
We do not have to use this setting and could change our speed on the fright plans if required. It just takes a little bit of time to adapt, e.g. when the wheel is re-invented with new check lists or advisory calls or the latest fly-by-talk system.
Cheers
PS Maybe slow or slug or something similar needs to be added to the callsign, with company and ATC approval of course!
