Before the landing gear is extended, what chime is given?

• A. Hi/Lo
• B. Single
• C. Double
• D. Triple

Answer: (A)

Audible cues in the cockpit use distinct chime patterns to signal different actions or configurations. The two-tone Hi/Lo sequence is the specific alert used to indicate that the landing gear is about to extend, so the pilots know to prepare for gear deployment and verify the gear indicators and handle position. This pattern is chosen because it’s easy to recognize quickly, even in a high-workload environment, and it stands apart from other chime patterns that signal different conditions. The other chime patterns—single, double, or triple—are used for other alerts or warnings, not for gear extension, which is why the Hi/Lo cue is the best answer here.
