Turn the raw legal text into a practical explanation grounded in Manual of Standards Part 173—Standards Applicable to Instrument Flight Procedure Design.
(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.
