Well, I can't put any proffesional input on flying and related procedures, but my English is good enough for a fairly exact translation of idioms.
So I'll put in my "2 cents" (in Russian it would be "5 kopeks")
What Krasnokutskiy was saying means "Calm down"- "Stay cool" -"Stop worrying".
So no subtle indications of possible error or wandering attention are present.
