Which statement describes ALC C1 (X)?

• A. ALC C3 description.
• B. ALC C2 description.
• C. ALC C1 (X): Temporary or mild conditions requiring medical follow-up but whose condition is clinically quiescent (inactive or unlikely to cause serious impact) if untreated or treatment is limited to primary care during periods of deployment or assignment.
• D. No medical limitations apply.

Answer: (C)

ALC C1 (X) describes conditions that are minor or temporary and still require some medical follow-up, but are clinically quiescent if untreated or when management is limited to primary care. This means the condition doesn’t pose a serious risk to flight duties and the individual can continue deployment or assignment while being monitored, rather than being fully disqualified. The other descriptions imply either more severe or different levels of impact—C3 indicates more serious conditions, C2 a different, more restrictive level, and saying no medical limitations apply would ignore the need for follow-up and primary-care management.
