Negative ghost rider. If it's not stated and you don't have or have an stc you can't use it. It is that simple.
You cannot make your own rules.
yr right,
Maybe that is what you think is the case, been taught, whatever, but it is not legally true, as far as aircraft certification is concerned. However, if one has been "trained" in Australia, either as a licensed pilot or maintenance person, I can easily understand how that legal misapprehension comes about.
As mentioned previously, a POH, by whatever name, is a combination of certified data, approved/acceptable data, and selected useful information for the operation of the aircraft by suitably trained, experienced and licensed crews.
In matters of LOP, if it is not specifically prohibited, it is permitted, as LOP is a quite normal operating mode for a four cycle (Otto Cycle) piston engine, aircraft or otherwise.
