If the letter Z is used, specify in Item 18 the other  equipment carried or other capabilities, preceded  by COM/, NAV/ and/or DAT, as appropriate.  If the letter R is used, the performance based naviga- tion levels that can be met are specified in Item 18  following the indicator PBN/. Guidance material on the  application of performance based navigation to a  specific route segment, route or area is contained in  the Performance-Based Navigation Manual (Doc RNAV- equipped aircraft capable of flying RNAV SIDs putting “NO SID” in the remarks section will not alw result in a clearance via a Preferential Departure Rout (PDR). The Pilot/Dispatcher must amend Field 18 NAV  from D1 to D0 and remove PBRN RNAV1 Code If a RNAV DP is filed, an ICAO fligh In Field 18, Pilots/Dispatchers must file a D1 or D2  depending on the RNAV DP. Additionally, Field 18  should include PBN/D1-D4 depending on the naviga- tion update source. See AIM/PANS ATM 4444 for ICA filing procedures.  RNAV Q-routes require en route RNAV 2, corr NAV/E2 code and PBN/C1-C4 based on navigation  system update source.  If an aircraft does not meet the requirements for RVSM, then the W filed in ICAO flight plan Field removed and STS/NONRVSM must be annotated in  Field 18.  Filing requirements for RNAV STARS. Field 18 of the  ICAO flight plan must have a NAV/A1 or A2 assigned the RNAV STAR. Additionally, PBN/D1-D4 for RNAV1 C1-C4 for RNAV2 should be filed. If unable to accept RNAV STAR, the flight plan must be amended t the NAV/A1 or A2 to A0.
