Good evening,
I was wondering if it is possible to add the RNP requirements to the route that are being flown on the map or on the route segments. All routes have their RNP requirement, these are found in the Jeppesen Route Manuals. In real life, the app shows them. It would be a very nice addition as when flying we can check the RNP value against the one given by the aircraft database and change it accordingly in case it is different. Example: PMDG is giving always RNP 2 en route but in some routes this can be higher. It seems the database of most sim aircraft is not including this nowadays so would be very helpful in Navigraph Charts!
Thank you 
Problem is that that data isnt located anywhere in the ARINC 424 data; it would more than likely have to be a manual process. In most cases, its not individual airways but airspaces (like NAT DLM).
I know Lido Enroute charts have the RNP requirement on the physical chart, but Jepp charts don’t.

Thanks for the answer doug!
I don’t know exactly from where they take the data in real life, maybe is a manual process like you said. Maybe would be nice to add an option to manually put a note on the map, in case we know the requirement in a specific airspace. Like you said, for example, I know in NAT HLA it is RNP4, so I change it normally in PROG page pag 3/4. But would be nice to have this addition to add a note on the map, if not already present. Maybe there is and I do not know 
Thanks!
It comes from the text pages from the operator’s charting provider; so Jepp’s Airway Manual, or the Lido RSI Pages.
