10.6.13         Distance Separation minima using RNAV with Automatic Dependent Surveillance – Contact

Minima               Application                                              Conditions                                                                                                                                                                                                                                                                                                                                                   Diagram
A1                   Aircraft cruising, climbing or descending on same track    1. Separation must be established in accordance with subsection 10.6.10.

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.
                                                                                3. If an ADS-C periodic report is not received within 3 min of the time it should have been sent, action must be taken to establish communication. If communication is not established, or a periodic report is not received within 8 min from the time the periodic report should have been received, an alternative form of separation must be applied.
                                                                                4. Both aircraft must be approved either RNP 10 or RNP 4.
                                                                                5. Subject to subsection 10.6.7.11, distance or periodic ADS-C reports must be obtained at least every 24 min.

                                                                                3. Before the application of this standard, a Demand Contract Request (One shot) must be transmitted to each aircraft concerned.

Section 10.7:   Separation Standards—Vertical

10.7.1              Vertical Buffers between Aircraft Inside and Outside Controlled Airspace

10.7.1.1         Levels assigned to VFR aircraft must provide a buffer of at least 500 FT with the base of CTA.

10.7.1.2         If the base of CTA is a VFR level, levels assigned to IFR aircraft must provide a buffer of at least 500 ft with the base of CTA. If it is known that an IFR aircraft is operating less than 500 ft below the CTA base, levels assigned must provide a buffer of at least 1 000 ft with the base of CTA.

10.7.1.3         Where the base of CTA is an IFR level, levels assigned to IFR aircraft must provide a buffer of at least 1,000 FT with the base of CTA, unless it is known that no IFR traffic is operating at the base of CTA. In this instance a buffer of at least 500 FT must be applied.

10.7.2              Vertical Separation Below High Altitude Balloons

10.7.2.1         Unless visual separation is applied, aircraft in CTR/CTA must not be permitted to transit vertically below the 15 NM radius of the balloons position while the balloon is ascending until the balloon has passed FL600.
