Which braking action code corresponds to 'good to medium'?

• A. 4
• B. 5
• C. 3
• D. 2

Answer: (A)

Braking action codes summarize how well braking works on a runway, based on tire grip and deceleration. The phrase “good to medium” describes braking action that sits between the good level and the medium level—mid to high in effectiveness. In this coding scheme, that exact descriptor is assigned to the code that represents that range, making it the best match for the sequence of braking performance described. The other codes map to descriptors that are either stronger or weaker than this range, so they don’t fit as precisely.
