How long does a Statement of Demonstrated Ability last?

A Statement of Demonstrated Ability (SODA) is an essential document for pilots who have certain medical conditions that could otherwise disqualify them from obtaining a medical certificate. The main purpose of a SODA is to allow these individuals to demonstrate that they can perform safely despite their medical conditions.

The correct answer indicates that a SODA does not expire as long as the pilot’s condition remains stable or does not worsen. This means that the pilot can continue to hold a valid medical certificate as long as they are able to show they can meet the necessary standards related to their medical condition. If their condition changes or deteriorates, the FAA may require reevaluation, potentially impacting the validity of the SODA.

Other durations listed in the options are not applicable to a SODA due to the fact that its validity is contingent on the stability of the individual's medical condition, rather than set time limits. Understanding this concept is crucial for pilots managing ongoing medical concerns, as it allows them to continue flying as long as they are capable of doing so safely.
