LOKE,
This falls into that murky zone of the FAR's. We develop Engine Failure Procedures to enhance takeoff weights regardless of the SID's. For obvious reasons if the engine fails at V1, the aircraft must follow the OEI procedure to ensure obstacle clearance. However, if the engine doesnt fail, there isnt a requirement to follow that procedure, nor is there a requirement to assess the ALL engine flight path!
