THE MARCH TO PBN

摘要

Many of us routinely use GPS as sole-source navigation throughout our flights. Congratulations; you're leveraging the benefits of Performance Based Navigation. That's good. We have thousands of RNAV (GPS) approaches, many with vertical guidance, and they're far safer, more reliable and more accurate than ground-based approaches. We often fly direct or nearly so. All these advances are reshaping the National Airspace System (NAS) and the way we fly IFR, but PBN is still young. In October 2016, the FAA published the PBN NAS Navigation Strategy 2016. It shows how full-scale deployment of PBN's many features will be realized in three terms. We are presently in PBN's near term, 2016-2020, followed by the midterm spanning 2021-2025 and the far term, 2026-2030. Let's look inside that paper to get a preview of what to expect in the future.
