Which of the following is NOT a restriction for pilots operating under BasicMed?

The correct answer reflects the fact that one of the key aspects of BasicMed is designed to provide greater flexibility for pilots. Under BasicMed, pilots are allowed to operate with more than five passengers, which distinguishes it from certain other flying regulations. This means that as long as they meet the requirements and restrictions set forth, they can indeed conduct operations with more passengers, which makes it more accommodating for general aviation pilots.

Conversely, the other options presented represent restrictions that BasicMed pilots must adhere to. For instance, pilots operating under BasicMed are limited to flying aircraft that weigh no more than 6,000 lbs, which is aimed at ensuring safety and ensuring that pilots do not operate larger, more complex aircraft without the requisite certification. Additionally, pilots must remain within the United States and are restricted to flying at or below 18,000 feet mean sea level. These limitations help maintain safety and regulatory compliance for those pilots opting to operate under this program.
