What does BRAN indicate in braking action terminology?

• A. Brakes Are Normal
• B. Braking Action is Noted
• C. Braking Action is Limited
• D. Braking Action is Nil - can't land, no traction

Answer: (D)

Braking action describes how well a runway will slow an aircraft, especially when the surface is contaminated. The term BRAN is used to indicate braking action is Nil, meaning there is no usable deceleration at all. When braking action is nil, landing and rollout are not safe because the aircraft cannot slow effectively, so diversion or a different runway would be required. Other levels like normal, noted, or limited imply some deceleration is available, even if reduced. Nil is the most severe category, signaling that the runway cannot be trusted for landing with a normal stopping performance.
