In response to significant questions and concerns regarding the implementation of the revised aircraft equipment suffixes contained in AC 90-100 and the Airman’s Information Manual, the NBAA was able to obtain some clarifications and guidance from the FAA. According to the NBAA website, “the FAA is creating a web site where a current list of compliant equipment can be found, (2) the FAA is developing a web based RAIM prediction capability – until then RAIM prediction does not need to be done for any RNAV route conducted where ATC provides radar monitoring or RNAV departure/arrival procedure which has an associated “RADAR REQUIRED” note charted, and (3) a clarification stating operators with FMS which incorporate IFR GPS sensors should use the /G or /L suffixes consistent with RVSM approval status.”
The new suffix table is effective September 1, 2005. You can obtain more information regarding the topic at the NBAA’s website here.
