When an aircraft is responding to an RA, traffic advisories and safety alerts regarding terrain and obstructions should be provided for ___.

• A. all aircraft in Class E airspace
• B. the aircraft responding to the RA and all other aircraft under your control jurisdiction
• C. the aircraft responding to the RA only
• D. all other aircraft under your control jurisdiction

Answer: (B)

When a Resolution Advisory is in effect, you must keep every aircraft under your control aware of potential hazards, including traffic and terrain or obstructions. The aircraft responding to the RA is actively maneuvering to avoid a conflict, but other airplanes in your control can also be affected by that maneuver or by nearby terrain/obstacle threats. Providing traffic advisories and safety alerts to both the RA aircraft and all other aircraft under your jurisdiction helps each pilot maintain situational awareness and coordinate safer separation. This duty does not extend to aircraft outside your control, and it isn’t limited to only the RA aircraft or only to other traffic—the key is informing every aircraft you’re responsible for so they can respond appropriately.
