What does “ X miles in trail, runway 25R cleared to land” mean?












7












$begingroup$


I was listening to the LiveATC Phoenix North Tower feed as he was clearing aircraft to land. He said something like "Southwest fifteen sixty five, Phoenix Tower, (aircraft type), X miles in trail, runway 25R, cleared to land".



What does the "(aircraft type) X miles in trail" portion mean?



Is the controller pointing out the aircraft behind the aircraft that is being given the landing clearance? If yes, why would the aircraft in front care?

The controller's telling Southwest 1565 it's cleared to land (otherwise they would use the other aircraft's identification), and by the way there is an airplane of a certain type coming up behind and to take that into consideration in the event that Southwest 1565 was thinking of spending too much time on the runway after landing instead of promptly getting out of the way.



That kind of comment added to the landing clearance suggests that the airplane behind is a little closer than usual, or is going significantly faster, or it's just really busy with airplanes spaced at minimum separation, and Southwest should expedite clearing the runway.

    This is standard phraseology, and is in the pilot controller glossary. It may also be expressed in "minutes in trail".

I highly doubt you heard the controller correctly, or understood what he was actually saying. Sometimes, the words are spoken quickly and to a novice, is illegible. Also, LiveATC radios are volunteer hosted and not the same as what controllers and pilots actually hear.



I suspect the controller was issuing the traffic AHEAD of the landing traffic. Typically tower controllers issue the traffic AHEAD in the sequence, not behind. I highly doubt a controller would expect a pilot to "figure out" that the mileage call for someone behind him meant he needed to expedite off the runway. Rather, it would include some "slang" language, "expect no delay off the runway, traffic is close behind." If it was being issued multiple times and you heard it repeatedly, you likely heard him letting the trailing aircraft how far behind the traffic ahead of them they were. Lastly, the controller may have been omitting (or you weren't hearing) a key word in the clearance that changed the context. I highly doubt the controller was issuing the trailing traffic to the leading traffic 10+ times in a row.

    I don't have a reference because it's purely a technique used by air traffic controllers, neither is required beyond the "Standard phraseology" of issuing traffic (as cited a little out of context) in the above answer.I suspect any "reference" provided to the contrary will be out of context. If we could hear the actual tapes (OP could provide the date/time they were listening) we could "hear the evidence" for ourselves, as I believe the OP misheard the controller.
