Which option is not part of the corrective actions for inadvertent IMC?

• A. Announce Inadvertent IMC
• B. Establish Instrument Scan
• C. Establish Safe Altitude, Airspeed, and Heading
• D. Squawk 7600

Answer: (D)

When you unexpectedly enter instrument meteorological conditions, the priority is to regain control by flying with reference to the instruments and stabilizing the flight path. The corrective actions focus on communication within the crew, establishing a reliable instrument scan to determine attitude and flight path, and setting conservative, safe parameters to maintain terrain clearance and begin a return to VMC if possible. Announcing that inadvertent IMC has occurred helps coordinate the crew and ensures everyone is focused on the same task. Establishing an instrument scan is essential because visual cues are unreliable, so you must rely on the attitude indicator and other flight instruments to hold a stable, controlled flight. Setting a safe altitude, airspeed, and heading is about maximizing your margin for error and making deliberate, predictable adjustments to steer toward better weather or a safe area.

Squawk 7600, on the other hand, is the transponder code used to indicate a loss of radio communications. While important in a separate communications failure scenario, it is not part of the corrective actions for inadvertent IMC itself.
