A statement granted at the discretion of a Federal Air Surgeon to a person who is disqualified from obtaining a pilot's medical certification. Granted only if the disqualifying condition is static or non-progressive, and the person has been found capable of performing airman duties without endangering public safety. A Statement of Demonstrated Ability does not expire and authorizes a designated aviation medical examiner to issue a medical certificate of a specified class if the examiner finds that the condition described on its face has not adversely changed. In granting a Statement of Demonstrated Ability, the Federal Air Surgeon may consider the persons operational experience and any medical facts that may affect the ability of the person to perform airman duties.

“If we do take statements to be the primary bearers of truth, there seems to be a very simple answer to the question, what is it for them to be true: for a statement to be true is for things to be as they are stated to be.”
—J.L. (John Langshaw)
“That three times five is equal to the half of thirty, expresses a relation between these numbers. Propositions of this kind are discoverable by the mere operation of thought, without dependence on what is any where existent in the universe. Though there never were a circle or triangle in nature, the truths, demonstrated by Euclid, would for ever retain their certainty and evidence.”
—David Hume (1711–1776)
“The most striking aspect of linguistic competence is what we may call the ‘creativity of language,’ that is, the speaker’s ability to produce new sentences, sentences that are immediately understood by other speakers although they bear no physical resemblance to sentences which are ‘familiar.’”
—Noam Chomsky (b. 1928)
