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.

Conclusion – Are we ready to go?

9PBN and Regional Aircraft

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.

Conclusion – Are we ready to go?
