a nominal gradient greater than 5%, the IAL chart must show a climb gradient identified by an asterisk.

8.1.1.5              Prohibited and Restricted (P and R) Areas. Procedures which cross or abut P and R areas must be designed so that:

(a)         where the P or R area contains flying activities:

(i)            horizontally, the boundary of the P or R area does not infringe:

(A)        for holding—the primary holding area plus a 1 NM buffer;

(B)        for non-precision approach segments:
                                the primary area of Initial and Intermediate Approach segments plus a 1 NM buffer, and
                                the primary and secondary area of the Final Approach segment;

(C)        for precision approach segments—the OAS W and X surfaces plus a 1 NM buffer.

(ii)          vertically, the altitude limit over the area must be the vertical limit of the P or R area plus 500 ft, or the altitude dictated by obstacle clearance criteria, if higher.

(b)         where the P or R area is not used for flying activities:

(i)            horizontally, the boundary of the P or R area must not infringe:

(A)        for holding—the primary holding area;

(B)        for non-precision approach segments—the primary area of the Initial, Intermediate and Final approach segments;

(C)        for precision approach segments—the OAS W and X surfaces;

(ii)          vertically, the upper limit of the P or R area may be used provided obstacle clearance criteria are met.

(iii)        for the Missed Approach Segment, clearance from airspace is determined using a combination of vertical and horizontal dimensions:

(A)        vertically, the height of the nominal aircraft position in a missed approach is determined by applying the techniques of PANS‑OPS Vol II, or ICAO Doc 9905 missed approach criteria, using a gradient of 5% from the SOC to the missed approach altitude;

(B)        if this height conflicts with a P or R area, then horizontally the missed approach primary and secondary areas must not infringe the P or R area boundary.
Note: If a gradient of greater than 5% is required, the IAL chart must show the climb gradient identified by an asterisk.

8.1.1.6              Danger Area Associated with High-Velocity Gas Efflux. Procedures which cross or abut danger areas associated with high-velocity gas efflux must be designed so that:

(a)         for procedures based on conventional navigation aids:

(i)            horizontally, the danger area does not infringe the procedure primary area.

(ii)          vertically, the upper limit of the danger area may be used provided obstacle clearance requirements are met.

(b)         for GPS based procedures:

(i)            horizontally, the nominal final approach and missed approach tracks clear the danger area by a minimum of 1,000 m;

(ii)          vertically, the upper limit of the danger area may be used provided obstacle clearance criteria are met;

(iii)
