In instrument flight, what does a lack of cross-check indicate about situational awareness?

• A. It has no impact on safety.
• B. It can lead to unrecognized attitude, altitude, or airspeed deviations and increases risk.
• C. It improves reaction time.
• D. It only affects autopilot.

Answer: (B)

Cross-check is the ongoing process of scanning and comparing the aircraft’s instruments to build a coherent picture of what the plane is actually doing. In instrument flight you’re constantly watching attitude, altitude, and airspeed and then reconciling what each instrument shows. When you don’t maintain that cross-check, small errors or discrepancies can slip by without being noticed. You may think you’re level when you’re not, or you may miss a slow descent or a speed change, because you’re not actively confirming that all indications agree. That gap in awareness means deviations from the desired flight path can go unrecognized, which markedly increases risk. Regular cross-checking helps catch instrument errors or disturbances early and keeps your situational awareness accurate, guiding timely and appropriate actions.
