R3                  Climbing, cruising or descending                                                 1. When both aircraft are climbing to non-vertically separated levels:
30 RNAV                                                                                              (a) both A and B must report reaching their cruising levels; and
                                                                                                     (b) if B reports at the cruising level first, immediate action must be taken to ensure separation is maintained.
                                                                                                     2. May only be used in CTA.
                                                                                                     3. Aircraft must be approved:
                                                                                                        (a) AUSEP; or
                                                                                                        (b) GPSRNAV; or
                                                                                                        (c) GPSOCEANIC; or
                                                                                                        (d) RNP10; or
                                                                                                        (e) RNP4.
                                                                                                     4. When using DME-derived information for level changes above FL 290, both aircraft must be on the same side of the DME beacon.
R4                  Aircraft cruising, climbing or descending on same track                          1. Separation must be established by reference to the same 'on-track' waypoint, whenever possible ahead of both aircraft or by use of ADS-C.
50 RNAV                                                                                              2. Distance reports obtained by CPDLC must be sent by both aircraft at the same time or from the leading aircraft first.
                                                                                                     3. When aircraft are at, or expected to reduce to, the minimum, speed control techniques, including assigning Mach number, must be applied to ensure that the minimum distance exists throughout the period of application of the standard.
                                                                                                     4. If an aircraft fails to report its position within 3 min, immediate action must be taken to establish communication. If communication is not established within 8 min from the time the report should have been received, an alternative form of separation must be applied.
                                                                                                     5. Both aircraft must be approved either RNP10 or RNP4.
                                                                                                     6. Subject to subsection 10.6.7.11, distance reports must be obtained at least every 24 min.
R5                  Definite Passing                                                                 1. Reports (including ADS-C reports) must indicate that the aircraft have passed and the distance between them is opening.
50 RNAV                                                                                              2. Both aircraft must be approved either RNP10 or RNP4.
R6                  Aircraft cruising, arriving and changing levels when not vertically separated    1. No closing Mach number may exist.
80 RNAV                                                                                              2. The Mach Number Technique (MNT) must be applied during the application of the standard.
Mach No. Technique                                                                                   3. Aircraft must be approved:
                                                                                                        (a) AUSEP; or
                                                                                                        (b) GPSOCEANIC; or
                                                                                                        (c) MNPS.

                                                                                                   Note: The requirement for 'no closing' may not be waived.

R7                                                                                                   1. Using the same waypoint, reports must indicate that the aircraft have passed and the distance between them is opening.
80 RNAV                                                                                              2. Aircraft must be approved:
Definite Passing                                                                                        (a) AUSEP; or
