Instrument Rating Checkride Practice Test

For an instrument approach, a pilot must have an IFR clearance, appropriate approach plates or charts, and knowledge of weather minima, making this the correct choice.

An IFR clearance is essential as it provides authorization from air traffic control to operate under instrument flight rules, ensuring that the pilot is legally permitted to conduct the approach in instrument meteorological conditions. The approach plates or charts are crucial because they contain the detailed information necessary for flying the specific approach procedure safely, including altitudes, fixes, and navigational aids.

Knowledge of weather minima is also vital as it determines whether the approach can be legally and safely completed based on the current weather conditions. This includes understanding the minimum visibility and ceiling requirements associated with the particular approach being flown.

In contrast, the other options lack one or more critical components that are necessary for a safe and compliant instrument approach. For instance, simply having an IFR clearance and adhering to visual flight rules would not fulfill the requirements since instrument approaches involve operating within controlled instrument conditions. Additionally, needing a special endorsement from a flight instructor or relying on a secondary flight plan and the approval of a co-pilot does not align with the standard regulations and requirements in place for conducting instrument approaches.
