Which of the following is a requirement for a pilot to act as pilot-in-command under IFR?

To act as pilot-in-command (PIC) under Instrument Flight Rules (IFR), a pilot must fulfill specific regulatory requirements to ensure proficiency in instrument navigation and safety. The correct option highlights that a pilot is required to have completed six instrument approaches and successfully passed an instrument proficiency check.

This requirement is significant because it ensures that the pilot maintains a high level of skill in flying under instrument conditions, which can be challenging and demanding. The six instrument approaches confirm that the pilot has recent experience in landing an aircraft using instruments alone, which is crucial during low visibility or adverse weather conditions. Additionally, passing an instrument proficiency check indicates that the pilot has received thorough testing and checks on both their knowledge and practical abilities to operate an aircraft effectively under IFR conditions.

The other options do not adequately address the regulatory requirements for IFR PIC duties. For example, simply logging three instrument approaches without the proficiency check does not meet the necessary standards for safety and skill. Similarly, six instrument flights under actual IFR conditions, while beneficial, do not specify the required approaches or a proficiency check. Finally, completing three night flights with passengers is not relevant to IFR proficiency, as it does not focus on instrument flight capabilities. Thus, the importance of maintaining flight proficiency in instrument scenarios is clearly emphasized by
