What is the signal for out-of-sterile cockpit?

Explanation:
Two tones are used as the cue that the cockpit is out of sterile conditions, meaning it’s now permissible to resume nonessential communication and activities. The sterile cockpit rule requires pilots to minimize talk and unnecessary tasks during critical phases like taxi, takeoff, and approach. When those critical activities are complete and it’s safe to talk again, a brief two-tone signal is sounded to alert both pilots that normal conversation may resume. A single tone, silence, or three tones would not reliably indicate this transition, so two tones provide a clear, concise cue without being intrusive.
