I thought I had seen some discussion on this but nothing showed up in a search.... I've had my IR for a couple of years now. When I first started using it I would slow to approach speed after passing the IAF so I wouldn't get behind the airplane (as much anyway). Now it seems like I'm just dragging it in between the IAF and the FAF. I also don't like knowing other IFR flights might be waiting on me before they can depart or start their approach. I was wondering if there was a general rule on when you slowed to approach speed and why.
