There is a lot of information on how the pilot should ask the ATC to repeat a statement, but is there a standard way for the ATC to ask the pilot to repeat a readback, or any new information that the pilot provides?

  • $\begingroup$ If they are busy on another frequency or on a landline, I will frequently get, “Aircraft calling Center, go ahead”. I also hear, and have occasionally gotten, “N123 Say again intentions”. It’s their way of saying that what you asked for doesn’t make sense and giving you a chance to clarify. But mostly they just didn’t catch what you said and need you to repeat it. $\endgroup$ – JScarry Jan 29 '17 at 15:04

    $\begingroup$ @JScarry The excuse of the controller being on the landline is so common that I've heard pilots jokingly use it, too. "X Center, Say Again. I was on the landline." :) Whether ATC is amused is another question... $\endgroup$ – reirab Jan 30 '17 at 20:56

Yes, and it is exactly the same: Say again.

Station calling Georgetown Ground say again your callsign

Lufthansa 123 say again speed

Scandinavian 123 say again all after 'good morning'

Or simply

United 345 say again

    $\begingroup$ Don't know why i thought it would be different actually, given the structured nature of communication. Thanks! $\endgroup$ – Priyank Jan 29 '17 at 8:22

In the pilot/controller glossary:


Definition: Used to request a repeat of the last transmission. Usually specifies a transmission or portion thereof not understood or received; e.g., "Say again all after ABRAM VOR."

Notice this glossary is specifically "pilot/controller" they use the same terminology. There is no separate "controller-only" and "pilot-only" glossary of ATC terminology.
