RNAV
I list my aircraft equipment in item 10 of the ICAO flight plan as SYRG/S (its a Cessna 172). I use G because the aircraft have an IFR certified GPS and I list R as it has BRNAV(RNP-5). I recently read that the inclusion of R indicates that the aircraft meets the RNP type for the route flown. If I fly from an airport with a BRNAV SID (RNP-5) to an airport with a PRNAV STAR (RNP-1) should I omit the R and if I do how does ATC know I have BRNAV equipment. I ask because it can be very useful to be able to fly a BRNAV SID but I don't want ATC at the destination airport to plan on offering a PRNAV STAR only to be told "unable" by me. What would you recommend.
