The need for speed is hard wired into humans, it seems. Even those of us who enjoy flying slow also love the idea of eating up the miles in some fast cruiser. A flight that turns a three-hour driving ordeal into a 25-minute aerial jaunt becomes a bragging right for any pilot. Other than the pure thrill of logging a high groundspeed, going fast is only useful when you’re going somewhere. If perhaps your goal is aerial sightseeing then slow (and probably low) is the way to go. If you have to go fast, remember that old saying from auto racing: “Speed cost money; how fast do you want to go?” This equally applies to aviation. FAA actually drew a speed line back in the early 2000s when the SP/LSA rule was being written (just as now with the LSA 2023 rule in the works). No, I don’t refer to the 120-knot speed limit we’ll discuss below.
