Training course
SoB
To get approval to fly RNAV in EASA land you must be certified by your authority of a/c registration. I do not have the UK CAA form on me at the moment but I can find it easily if needed. Part of the approval for RNAV from BRNAV through to RNPAPP is that you submit a copy of your training programme. Use the document I placed a link to and write yourself a seriously difficult quiz based on the key points you read in the document, submit it with your RNAV aopplication and this becomes your approved course. PM me if you wish to discuss over the telephone.
