The LO chime timing before landing is approximately how many minutes?

• A. 1 minute
• B. 3 minutes
• C. 5 minutes
• D. 10 minutes

Answer: (B)

This is about a fixed cabin readiness cue that signals the crew to start final pre-landing tasks. The LO chime is timed to occur about three minutes before touchdown, giving a reliable window to complete safety checks and prepare passengers for arrival. Three minutes is short enough to keep the crew focused on approaching and landing, but long enough to finish required steps like securing galley items, ensuring seat belts are fastened, and briefing passengers. If the alert happened much earlier, the tasks could lose their urgency or be forgotten by touchdown; if it happened much later, there wouldn’t be enough time to finish everything safely before landing.
