There are a lot of vague statements being made around here by folks quoting or referencing obscure documents, regulations, and "law" re landing in any old place. It would be nice if folks would cite specific references they think apply to the situation rather than offer up vague recollections of what some source may have probably suggested.
One example...
If I recall correctly it also says in the FAR that you can deviate from any regulation in an emergency such as to save somebodies life.
Just where in the US FAR's does that statement come from. Give us a cut and paste of the wording...and the reference for that.
Ask yourself if the definition of "Emergency" as used by the FAA in the FAR's applies to the everyday conduct of EMS helicopter operations? Then, provide us the citation of the source you are using to make that claim please.
Now if you begin to use the FAR/AIM (Airman's Information Manual) as a reference you should also read what it says about it being a reference and accumulation of "recommeded practices" and the admonition those same practices do not carry the weight of rule or law.
The UK Air Law appeared to grant far more leeway in the accetable actions by pilots during "Life Saving" efforts than does the US FAR's.
Perhaps we could get Flying Lawyer to compare and contrast that for us if it would not be a violation of legal standards in the UK for him to do so.
