Category II approaches are prohibited when braking action is reported as less than?

• A. Good
• B. Medium
• C. Poor
• D. Excellent

Answer: (B)

Braking action describes how much friction the runway surface provides and is reported in qualitative terms like Excellent, Good, Medium, and Poor. Category II approaches rely on a minimum amount of runway friction to ensure safe deceleration and the ability to land and stop within the runway under reduced visibility. The required minimum is Medium, so braking action must be at least Medium to permit Cat II. If braking action is reported as less than Medium, the approach is not allowed because the runway may not provide enough deceleration. Thus, Medium is the threshold—Excellent or Good meet it and are acceptable, while Poor does not.
