During landing, which condition involves Excessive Asymmetry or Loss of Braking requiring abnormal procedures?

• A. During Landing - Excessive Asymmetry or Loss of Braking
• B. Touchdown with directional instability
• C. Sudden engine flameout
• D. Normal landing checklist

Answer: (A)

During landing, a situation where braking is lost or the aircraft experiences excessive asymmetry directly challenges the normal, controlled stopping process. This is precisely the scenario that requires abnormal procedures listed in the Quick Reference Handbook for landing. When braking performance is compromised or one wing/engine side dominates, normal braking, steering, and spoiler/reverse thrust use may not keep the airplane controllable or ensure a safe stop, so the crew follows the designated abnormal procedures to manage control, confirm system status, and decide on the safest stopping method or go-around if needed. This is why it’s the best answer: it matches the specific condition that triggers abnormal procedures. In contrast, touchdown with directional instability is a related but separate issue, engine flameout is an in-flight engine problem, and a normal landing checklist is not an abnormal situation.
