What is required for a person to operate an airplane in simulated instrument flight conditions?

To operate an airplane in simulated instrument flight conditions, the requirement is that the other control seat must be occupied by a safety pilot with at least a private pilot certificate. This is critical because in simulated instrument flight, the pilot at the controls may not be able to maintain visual reference to the ground or other visual cues. The safety pilot is responsible for monitoring the flight, ensuring safety, and providing assistance if necessary. This setup allows the pilot to gain experience in instrument flying while having someone qualified to take control of the aircraft if the need arises.

While other options reference various qualifications (such as needing a flight instructor or the qualifications of a second pilot), they do not align with the specific requirements set forth for simulated instrument flight conditions as outlined by aviation regulations. It is essential that the safety pilot has the proper certification to act competently in this role, thereby ensuring the safety of the flight operation.
