The FAA updated Order 8260.19G, detailing new national guidance for all FAA personnel responsible for implementing the U.S. flight procedures and airspace program. The order, which supersedes 8260.19F, also provides guidance for the military and other government agencies to use when interacting with the FAA regarding instrument flight procedures. Those procedures often determine the alignment and location of navigation facilities as well as the location, marking and lighting of airport landing and maneuvering areas.
FAR Part 95, explained in the new order, also establishes minimum en route, reception obstruction clearance and crossing altitudes, as well as maximum authorized altitude and changeover point, established by the FAA for instrument flight on federal airways. Changes include removal of “DME” from approach procedures that previously included that acronym in their name. In addition, the policy changes the naming routine for instrument procedures using “VOR/DME RNAV” to read “RNAV (VOR/DME).” The order offers guidance to determine the current magnetic variation (MV), as well as how to calculate the future MV for use in instrument procedure design and publication.
