    NEFAB (Free route airspace)

    Hello! As of Nov 12th, NEFAB was introduced in Norway, Finland, Estonia and Latvia. This effectively means that our region is now affected by two free route airspace blocks (FAB), NEFAB and DK/SK FAB. I've just started to scratch the surface of the available info on this, but in essence I think this means that operators are free to route as they wish through either block, but still need to plan via a significant waypoint, navaid or coordinate on the borders between the two FABs. The lower limits for free routing are F285 in DK/SK, F135 in Norway and F095 in Fin/Est/Lat. The plan is to unify these two FABs next summer (2016), to allow for free routing across the entire region. Here are two screenshots representing my understanding of a possible routing between BIKF and ULOO under the current system, and post-summer 2016 (note that I'm not certain if ENOB is part of this, there's a chance you need to add a sigpoint at the western border of ENOR if routing north of ISVIG) : Current system Summer 2016 Here's an introductory article on the topic: http://www.nefab.eu/dev/view/86 Here's a chart depicting mandatory arr/dep routes to/from ENGM when free routing is used: https://www.ippc.no/norway_aip/current/aip/EN_ENR_6_3-23_en.pdf
