What do we think of reducing speed to (your) slow flight speed as a mechanism to introduce spacing between you and the aircraft ahead?
My only concern with this is the pressure it puts on following aircraft, who may not be able to slow down as much. (60 Kts is a typical slow flight speed for what I fly).
Would you inform ATC that you were reducing speed for seperation purposes? (so that any aircraft following you would have an instant heads-up as to why you were getting closer!)
