To put it more succinctly, the FAA notes that the "various operating rules (91, 91K, 125, 121, and 135) have different requirements on aircraft departure and approach performance" and, "If AEO climb performance data is not provided by the manufacturer or otherwise furnished by the operator, pilots and operators must exercise sufficient care in determining expected takeoff/departure performance." Ensuring adequate climb performance exists to meet a SID, ODP, or DVA climb gradient under OEI conditions "does not adequately ensure compliance with the applicable OEI takeoff obstacle clearance operating rules" and the "FAA imposes no requirement, nor is it recommending, that operators use this FAA-approved AFM OEI performance data...
