What action is needed to specify a physical disability that does not affect the ability to fly safely?

The appropriate action to specify a physical disability that does not impede the ability to fly safely is obtaining a Special Issuance Authorization. This authorization allows individuals with certain physical conditions to be assessed on a case-by-case basis to determine whether they meet safety standards for flying.

The process typically involves providing medical documentation and, in some cases, undergoing additional evaluations or tests. The Federal Aviation Administration (FAA) has established guidelines for conditions that may require special issuance, recognizing that many physical disabilities can be managed effectively, enabling individuals to operate an aircraft safely.

In contrast, a Certificate of Fitness primarily refers to a simpler declaration of health that may not delve into the specifics of a physical disability. A Medical Examination is part of the process but does not inherently indicate that the examiner can authorize flying with a disability. An Airworthiness Certificate relates to the aircraft itself and does not pertain to the pilot's medical qualifications. Thus, Special Issuance Authorization is the correct and specific means to address a physical disability while ensuring safety standards in aviation are met.
