@OK465: what i wanted to convey with the second statement you quoted was: use it at your own risk. I guess it doesn't really contravene the first one.
Now, the FPV is a very handy tool, but be aware of the interconnections in modern aircraft systems and wary of added complexity in case of partial or complete system failures. Always be sure to keep those basic flying skills up, despite all the nice displays and computers they are still very much the basis of our job.
