Which phrase should be communicated when inadvertent IMC occurs?

• A. Announce Inadvertent IMC
• B. Establish Instrument Scan
• C. Maintain VMC
• D. Request a weather briefing

Answer: (A)

When inadvertent IMC occurs, the immediate priority is to alert everyone you’ve entered instrument meteorological conditions so you can switch to and rely on instruments. Saying “Announce Inadvertent IMC” communicates the exact situation right away, creating clear awareness for the crew and ATC and triggering the appropriate use of instrument procedures. It’s the concise, standardized way to acknowledge the hazard and begin corrective action. Establishing an instrument scan is essential, but it follows the initial declaration of IMC to ensure the crew is aware of the change in conditions. Maintaining VMC would be unsafe once you’ve entered IMC, and requesting a weather briefing is a planning activity rather than the immediate safety signal you need at the moment.
