What is the maximum speed allowed for a pilot operating under BasicMed?

The maximum speed allowed for a pilot operating under BasicMed is 250 KIAS. This regulation aims to provide a balance between safety and accessibility for pilots who may not have a current medical certificate but are healthy enough to operate an aircraft safely. The 250 KIAS limit is specifically significant as it ensures that pilots remain well within the operational envelope typical of smaller aircraft, which are the main focus of BasicMed.

Moreover, the intention behind this speed limit is to avoid exposing pilots to high-speed environments that could complicate the management of medical conditions or impair operational decision-making. For context, many general aviation flights happen under lower airspeeds, making 250 KIAS a sensible and practical limit for this policy. This threshold aligns with the operational capabilities of most aircraft used by non-commercial pilots, keeping safety and functionality at the forefront.

The other options exceed this maximum speed and fall outside the established guidelines for pilots operating under BasicMed, thereby reinforcing the rationale behind the limit.
