are you suggesting that one (ie corporate masters/pilots) need not worry about an engine failure during the miss .. on such a basis ?
not at all, what I am saying is, the driver cannot rely on the published MA procedure to be safe if they are OEI unless the procedure specifically states OEI and the climb gradient necessary.
Currently, the FAA requires all operators to have their OWN OEI procedures which must be approved by the FAA. Thus, most operators tend to use the published procedures, but evaluate the flight plan looking at the local conditions, especially temperature. The ac is then loaded according to those parameters, being weight limited as the performance changes per aircraft.
Given the multitude of configurations, it would be difficult to design OEI procedures without many caveats, hence the regulators usually put this on the operators. A public procedure, using the lowest common denominator, would be useless and an unreasonable constraint on most operators. (this is why the usual published OEI are something like a straight line to an altitude)
