Performance based navigation

from Wikipedia, the free encyclopedia

Performance Based Navigation (PBN, literally " performance-based navigation ") is a technology used in aviation to reduce emissions and increase efficiency in air traffic . It should also be the basis for the development of future ATM systems within the framework of SESAR and NextGen ( USA ). The ICAO has uniform here under the title PBN and globally applicable guidelines for the use of RNAV (Area Navigation) and RNP (Required Navigation Performance) created. The primary aim is to get away from ground-based navigation ( VOR , NDB , ILS ) and to increasingly rely on the use of satellite navigation . The main advantages of PBN procedures are, on the one hand, lower fuel consumption due to shorter routes and the associated reduction in emissions and, on the other hand, the possibility to fly around inhabited areas due to the more flexible design options for approach and departure procedures (keyword "Curved Approach") and thus to make a significant contribution to aircraft noise reduction.
