Flight Plan Form Section 10 is the "Equipment" section, where one input whatever navigation or communication equipment on board. In addition, Section 18 is the "Other information" section, where you can add any supplemental information, some of it in relation to the aforementioned "Equipment" section. My aircraft has every RNAV\RNP capabilities with indicators 1 through 10 (RNAV/RNP 10, RNAV 5, RNP 4, RNAV 2, RNAV/RNP 1). I need to use the "PBN\" indicator to detail PBN equipment capabilities. My question is how exactly?
In my case, should I file PBN\A1B2B4C2D2L1O2S1? Is it over the character limit? Is it actually necessary? Does it make sense?
