What is a requirement for a pilot who plans to conduct IFR approaches?

For a pilot to conduct Instrument Flight Rules (IFR) approaches, one of the key requirements is to complete a certain number of instrument approaches within a specified timeframe. This requirement helps ensure that the pilot maintains proficiency and familiarity with the procedures, which is crucial for safety when flying in IFR conditions.

Completing six instrument approaches within the last six months demonstrates that the pilot has recent experience and practice with the specific approach procedures, which include precision approaches (like ILS) and non-precision approaches (like VOR or NDB). This experience is necessary to ensure that the pilot is current, competent, and familiar with executing approaches amidst the conditions often encountered during IFR operations.

The other options do not specifically meet the established regulatory requirements for IFR approach proficiency. While logging hours and having a commercial pilot license are important elements of a pilot's qualifications, they are not specifically related to the ability to conduct IFR approaches in the same way that recent practice does.
