Which of the following is NOT one of the parameters to be established during inadvertent IMC?

• A. Altitude
• B. Airspeed
• C. Heading
• D. Bank Angle

Answer: (D)

When recovering from inadvertent IMC, you quickly set and maintain four stable flight references using the cockpit instruments: altitude from the altimeter, airspeed from the airspeed indicator, heading from the heading indicator, and attitude from the attitude indicator. The goal is to establish a predictable, controlled flight path based on those four references. Bank angle is not something you “establish” as a separate parameter in this scenario; you generally keep the wings level (minimal bank) to prevent unnecessary changes in altitude and airspeed while you regain situational awareness and control. Therefore, bank angle is the one not to be established during inadvertent IMC.
