How quickly should a pilot initiate the Resolution Advisory (RA) maneuver after it is displayed?

The correct response for how quickly a pilot should initiate the Resolution Advisory (RA) maneuver after it is displayed is within 5 seconds. This prompt action is crucial because the RA is a critical alert intended to prevent a potential mid-air collision. The timely execution of the maneuver helps maintain safe separation from conflicting traffic.

Following the RA guidance within the 5-second window ensures that the pilot acts swiftly enough to respond to the emerging threat, adhering to the protocols established for aviation safety. Delaying beyond this timeframe could diminish the effectiveness of the maneuver, as the aircraft may not be able to achieve the necessary separation in time, thereby increasing the risk of an incident.
