9. Scan the above situation. The radar controller should take the following action.
A. Apply merging target procedures to UAL412 and AAL927.
B. Issue traffic to AAL61 and A39716.
C. Apply merging target procedures to N126AP and A39716.
D. No action is required at the present time.
Answer: D. "Merging target procedures"
apply if targets will merge, and the altitude separation is at or less
than the required minimum, which is 2,000 feet above FL290. Everybody here
is separated by more than that, so nothing needs to be done.
