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
(a) 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.
(b) 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.
Single Site ARSR or FUSION Mode when target refresh is only from an ARSR or when in FUSION Mode - ISR is displayed.
(a) 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 assigned courses and/or radar vectors with an angular difference of at least 45 degrees, is considered a correct application of this paragraph.
(b) 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 Para 5-5-4, Minima, subparagraph g must be applied when wake turbulence separation is required.
NOTE: Apply en route separation rules when using multi-sensor mode.
EN ROUTE. Vertical separation between aircraft may be discontinued when they are on opposite courses as defined in para 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 Para 5-5-4, Minima, subparagraph g must be applied when wake turbulence separation is required.
EXAMPLE
“Traffic, twelve o'clock, Boeing Seven Twenty Seven, 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.)
