When I’m operating as Tower or Approach, a lot of pilots would come in too fast, above 250 kt while they are below 10,000 feet. They’re not supposed to do that, so sometimes I tell them “Maintain slowest possible speed” since Tower cannot specify the exact speed.
On the other hand, when I watch planes in the real-world landing sequence on Flightradar24, I noticed that a lot of them are doing 260-290 kt on approach and sometimes even 320-340 kt on departure, all well below 10,000 feet. That’s at VHHK.
So is there really a strict speed limit in the real world and is it enforced?
