Hi dirk85,
Thanks a lot for sharing your experience! I'm sorry you didn't make it.
Do not plan on any help from your PNF: he is not going to do almost anything. He will not even call for positive rate, for the minima, etc. He will answer to the radio, but he will not even change the frequency if you dont tell him to do so.
Regarding what you said about the PNF not calling for anything. Did you give him the specific commands to call for minima, altitudeXdistance, etc? And yet he didn't do it? Or was it already discussed during the briefing that he wouldn't give any calls despite any commands to do so?
