However, if you’re doing something different than preceding or succeeding traffic (even slightly different), it does stand out. So if they ask you to maintain 160, and you keep 165, that difference will be noticeable after a short while, if the others are doing 160 exactly.
And this is where the problem is, ATC expect us to fly exact speed of eg 160, but aircraft limitations due eg landing weight prohibit this to be done unless the big anchor is dropped down causing a lot of noise which no one wants.
Better would be a dialog with airlines, so that types unable to fly 160 at MLW are planned for at the appropriate speed they
can fly without dropping the gear, eg 165...
