Cross-check

What is cross-checking in Instrument Flight?

Cross-checking, also referred to as “scan,” is an essential skill in instrument flight that involves consistently and logically observing an aircraft’s instruments for attitude and performance information. This process ensures that the pilot gathers accurate and up-to-date information about the aircraft’s altitude, airspeed, heading, and other critical performance parameters, allowing them to make informed decisions and adjust the flight path as necessary.

During cross-checking, the pilot must keep a steady flow of attention between the instruments and refer back to each instrument frequently to confirm changes in attitude or performance. The goal is to maintain an accurate picture of the aircraft’s state, as well as to detect any deviations from the planned flight path and take corrective action promptly.

Accuracy and consistency are key when performing cross-checking in and promoting situational awareness. Pilots must develop a disciplined approach to scanning, ensuring that they take in all relevant information, interpret it correctly, and make necessary adjustments to the aircraft’s altitude, speed, and other parameters.

Overall, cross-checking is an essential technique for safe and effective instrument flight. Without it, pilots can easily lose their situational awareness and make critical mistakes that could endanger themselves and others. By developing and consistently applying the cross-checking skill, pilots can ensure that they are always in control of the aircraft and are flying safely and efficiently.
