February 18, 201016 yr Some help please.The manual states that 4L on POS REF PAGE will display RNP/ANP Data.My FMC (FS9) shows no Data in 4L.Any hint to solve this? Thanks
February 18, 201016 yr This is where they would be displayed if meaningful values existed for them. FSX does not support ANP for GPS (it can be safely assumed to always be 100%) and even though INS drift is sort of modeled, I don't think it is modeled well enough for any sort of ANP to be calculated. RNP is not (to the best of my knowledge) modeled at all. Paul Smith.
February 18, 201016 yr RNP is not (to the best of my knowledge) modeled at all.That is my opinion as well. I don't think it can be modelled with the syntax in the procedures files (sidstars). Not until we can reproduce arc-to-fix AF legs and the rest of the current ARINC model anyway. Also there is an altitude constraint limitation where they are all treated as 'level off at' instead of 'descend through.' Dan Downs KCRP
