A ' corrective ' RA requires __________.

A ' corrective ' RA requires __________.

• A. A lateral maneuver by the crew
• B. A vertical maneuver by the crew
• C. Immediate braking
• D. Autopilot disengagement

Answer: (B)

A corrective RA is resolved by changing altitude. When TCAS detects a potential collision, the corrective type of advisory tells you to perform a vertical maneuver—either climb or descend—to quickly restore vertical separation with the other aircraft. This vertical action is the most direct and reliable way to remove the threat within the short time frame before the encounter would be unsafe. Lateral maneuvers don’t guarantee separation in time, immediate braking doesn’t address the forecasted trajectory, and disengaging the autopilot isn’t required by this advisory. Follow the vertical command promptly, using pitch or vertical speed as needed, until the RA is cancelled.
