That's so true. I had to use selected speed on a second approach until 1300 feet AAL the other day in Incheon as the ATC asked us twice nervously to reduce to minimum approach speed. They asked us to perform a missed approach just before as the leading traffic took too long to vacate the runway. On his defense we were only 2.5 miles behind when he touched down and strong wind. On the second approach, Our VAPP was as fast as 160kt+ on an A 321 cat D in Conf Full instead of 145kt and the leading traffic was a 737 just 3 miles ahead. If I did not select speed, it would probably have ended to another missed approach.
