8 Basic RNAV capability already can bring significant benefits: Enroute optimization (using RNAV 5, RNAV 1 and 2), improving capacity and reducing fuel consumption, noise levels, etc.; Replacing conventional routes with RNAV routes leads to reduced maintenance of conventional navaids (eg:NDB, VOR); Terminal airspace optimization and reduced controller-pilot communication. Improves the predictability and situational awareness since it creates a repeatable ground track and patterns of depature and arrival. PBN and Regional Aircraft Conclusion – Are we ready to go?
9 Many of the current regional aircraft cannot meet more stringent PBN requirements without retrofits that are often too costly, e.g.: incorporation of a VNAV capability, inertial, etc. Due to current forecasts of service, the economics to justify such retrofit costs may not exist. Therefore we recommend: To explore more the use of RNAV basic capabilities; Consider that for more stringent requirements, the future airspace must accommodate those aircraft without major operational restrictions; Exemptions for mandates need to be considered; Standards and Requirements need to be frozen in advance of the expected entry into service. In general 3-5 years is necessary; Developments based on preliminary standards add risks and possible re-work. PBN and Regional Aircraft Conclusion – Are we ready to go?
