Interesting to hear a few variants from this used in the recent Dragon launch.

"good readback" to confirm that the other side has correctly readback the information just sent "go for ..." you have approval to...

but more often speaking relatively normally: they were having some problems with the hardline, at one point Dragon saying:

"that was an improvement but, uh, completely unreadable"

Most of the listed words/phrases are common in aviation so I’m not surprised to see them used in aerospace too!
