JO 7110.65 5-5-7

TERMINAL . In accordance with the following criteria, all other approved separation may be discontinued and passing or diverging separation applied when: Single Site ASR or FUSION Mode Aircraft are on opposite/reciprocal courses and you have observed that they have passed each other; or aircraft are on same or crossing courses/assigned radar vectors and one aircraft has crossed the projected course of the other, and the angular difference between their courses/assigned radar vectors is at least 15 degrees. NOTE-

Two aircraft, both assigned courses and/or radar vectors with an angular difference of at least 15 degrees, is considered a correct application of this paragraph.

The tracks are monitored to ensure that the primary targets, beacon control slashes, FUSION target symbols, or full digital terminal system primary and/or beacon target symbols will not touch. REFERENCE-

FAA Order JO 7110.65, Para 1-2-2 , Course Definitions.

Single Site ARSR or FUSION Mode when target refresh is only from an ARSR or when in FUSION Mode - ISR is displayed. Aircraft are on opposite/reciprocal courses and you have observed that they have passed each other; or aircraft are on same or crossing courses/assigned radar vectors and one aircraft has crossed the projected course of the other, and the angular difference between their courses/assigned radar vectors is at least 45 degrees. NOTE-

Two aircraft, both assignedcourses and/or radar vectors with an angular difference of at least 45 degrees, is considered a correct application of this paragraph.

The tracks are monitored to ensure that the primary targets, beacon control slashes, FUSION target symbols, or full digital terminal system primary and/or beacon target symbols will not touch.

Although approved separation may be discontinued, the requirements of paragraph 5-5-4 , Minima, subparagraph g must be applied when wake turbulence separation is required. REFERENCE-

FAA Order JO 7110.65, Para 1-2-2 , Course Definitions.

EN ROUTE , TERMINAL (when STARS Multi‐Sensor Mode is selected). Vertical separation between aircraft may be discontinued when they are on opposite courses as defined in paragraph 1-2-2 , Course Definitions; and You are in communications with both aircraft involved; and

You tell the pilot of one aircraft about the other aircraft, including position, direction, type; and

One pilot reports having seen the other aircraft and that the aircraft have passed each other; and

You have observed that the radar targets have passed each other; and

You have advised the pilots if either aircraft is classified as a super or heavy aircraft.

Although vertical separation may be discontinued, the requirements of paragraph 5-5-4 , Minima, subparagraph g must be applied when wake turbulence separation is required. EXAMPLE-

“Traffic, twelve o'clock, Embraer One Seventy, opposite direction. Do you have it in sight?”

(If the answer is in the affirmative):

“Report passing the traffic.”

(When pilot reports passing the traffic and the radar targets confirm that the traffic has passed, issue appropriate control instructions.)
