In a controlled ejection without intercom, which signal indicates completion of the checklist?

• A. Thumbs up after checklist run
• B. Hold pink pages up
• C. Three face curtain signals
• D. Verbal confirmation

Answer: (A)

In a controlled ejection without intercom, you need a quick, clear signal that the checklist is finished and everyone knows you’re ready to proceed. A thumbs up after the checklist run fits this perfectly: it’s a simple, nonverbal cue that is immediately visible, unambiguous, and can be given right at the moment the checklist is completed without relying on voice communication or special equipment. Other signals like holding pink pages up or three face curtain signals require additional conventions or visibility that may not be as universally understood or as reliably noticed in the heat of the moment. Verbal confirmation, while common with intercom, isn’t practical when intercom is unavailable, as it can be drowned out by noise or missed altogether. So, the thumbs up after the checklist run is the most reliable way to indicate completion.
