Everyone may well be correct about the value of such a film- I know how useful they can be on road vehicles. However undoubtedly, IMO, the feds would want to see it "installed" under some sort of mod procedure, authorised by an organisation with the necessary modification approval (involving reams of paper and associated costs).
In essence, it boils down to the system not trusting the common sense of a pilot/operator but requiring a more formal review. Sounds very "jobsworth" but the trouble is that the consequences of any "problem" can be dire on an aircraft.
Of course, someone could just do it. It would be fine until a keen fed spots it (not very likely as they usually just look at the paperwork these days), or worse in the event of there being a problem (probably less likely still) the insurance walks away.
