The OP later stated he/she was working on a B1.
"We have no idea what level of piloting knowledge your 'B1' licence give you and I feel we are wasting our time here with someone who cannot use a search engine.

This person may be be better suited posting in the eng/tech forum. None the less YOU should be best suited to answer this question being a seasoned pilot. Sir, you wasted only your time in this response.. I might guide him to the tech/engeneer forum for possible information.
Hey this thread kicked me in the short and curlys as today I had a PDIS "lost Vref and predictive info". I am sure it was an awakening for these gents to fly this jet with this loss.
On my end we have no FMS training other than what we gather as a group and share.... PILOT information helps mutch. I for one have learned how to set up an FMS for flight, predictive data came up to 10k.
My point is, the more we get from you, the more we return in share and likewise. In the end you will see there is no high horse.
