Depends on your Runway analisis criteria.Part 121 inthe states follows the FAA swath which is nearly as critical as the ICAO swath(much wider to cover crosswind effect-an further out).Ergo if one can follow a climb gradient of 200'/nm one can comply with the SID gradient.With an engine out,if the Obstacle clearance swath is formated on ICAO criteria one must take up a specific heading to clear the rocks.A lot of Co's have not adopted the Icao,ergo one might follow the Sid Routing with out the nescessary obstacle clearance..
