In instrument flight fundamentals, what does instrument cross scan emphasize?

• A. Reading a single primary instrument
• B. Scanning multiple instruments to determine attitude
• C. Visual scanning outside the cockpit
• D. Interpreting weather data

Answer: (B)

Instrument cross scan focuses on building a reliable picture of the airplane’s attitude by actively scanning more than one instrument and comparing their indications. In instrument flight, you can’t rely on a single gauge, because each instrument has its own possible errors or lag. By moving your gaze among the attitude indicator, turn coordinator (or rate-of-turn indicator), heading indicator, airspeed, and altimeter/vertical speed, you continuously verify that they tell a consistent story about pitch, bank, altitude, and rate of climb or descent. This systematic cross-check helps you detect errors, maintain situational awareness, and respond promptly to any deviation from the desired flight path.

The other options don’t fit because reading only one primary instrument provides limited information and is more prone to error; looking outside the cockpit is external scanning, not instrument cross check; and interpreting weather data is not part of the cross-check process for maintaining aircraft attitude.
