Referencing a new Information for Operators (InFO 19004) from the FAA, three NAT air navigation service providers may have started trials as early as March 28 of new separation minima using space-based ADS-B surveillance technology. Those Advanced Surveillance– Enhanced Procedural Separation (ASEPS) minima, which allow aircraft to fly closer to each other, conflict with established oceanic contingency procedures, prompting ICAO to develop new contingency procedures to ensure compatibility.
According to its website, the new procedures were published in ICAO’s NAT Ops Bulletin 2018_005 Rev 01, “Special Procedures For In-Flight Contingencies In Oceanic Airspace,” and in the Feb. 28 issue of the FAA’s Notices to Airmen Publication under the headline, “Procedures For In-Flight Contingencies In The New York Oceanic CTA/FIR During ASEPS Trial.”
NAT Ops Bulletin 2018_004 gives guidance to NAT operators on material they should include in pilot and dispatcher training programs and operations manuals to prepare them for NAT operations under ASEPS. The bulletin includes a description of a limited expansion of the performance-based communication and surveillance tracks.
“NBAA strongly urges members that fly in the North Atlantic region to ensure their flight operations teams are knowledgeable about these important changes,” said Brian Koester, NBAA’s senior manager for flight operations and regulations.
The changes to contingency procedures apply only to NAT airspace, not to Pacific or other regions. A single ICAO standard for contingency procedures is expected in November 2020.
Canada to Decommission VORs and NDBs
Nav Canada, the country’s provider of civil air navigation services, has finished a study of navigation aids and concluded that “given the comprehensive radar surveillance coverage, and the propensity of area navigation (RNAV) with global navigation satellite system (GNSS) equipped aircraft, many VOR and NDB navigation aids (navaids) are no longer required and should be decommissioned.”
The decommissioning process will be accomplished in 15 phases over the next seven years. Where a current NAVAID identified in the study serves as an instrument approach aid or anchors an airway segment, Nav Canada said it will “ensure that a RNAV/GNSS instrument approach procedures or RNAV airway segments are published, where required, before removal of the identified NAVAID.”
Aeronautical information circulars (AICs) will be published for each upcoming phase, Nav Canada said.

The first phase, consisting of decommissioning some 20 navaids are listed below and will start April 25. Corresponding aeronautical charts will also be amended.

= Port Hawkesbury (PD) NDB
= Bonaventure (YVB) NDB
= Bromont (ZBM) NDB
= Chute-Des-Passes (DG) NDB
= Salluit (YZG) NDB
= Smiths Falls (YSH) NDB
= Campbellford (YCF) VOR
= Hearst (HF) NDB
= Hornepayne (YHN) NDB
= Pelee Island (PT) NDB
= St-Bruno-De-Guiges (YBM) NDB = Ignace (ZUC) NDB
= Lansdowne House (YLH) NDB
= Ogoki Post (YOG) NDB
= Sachigo Lake (ZPB) NDB
= Aklavik (YKD) NDB
= Déline (WJ) NDB
= Lac La Biche (YLB) NDB
= Tulita (ZFN) NDB
= Williams Lake (WL) NDB
Nav Canada’s action follows the FAA’s decommissioning of legacy navaids that started in 2012.
FAA, NBAA Issue Joint Reminder on ADS-B Equipage Mandate
In late March, NBAA President and CEO Ed Bolen joined with Dan Elwell, acting administrator of the Federal Aviation Administration (FAA), to issue a reminder to the business aviation community to install Automatic Dependent Surveillance-Broadcast Out (ADS-B) equipment on their aircraft before the FAA’s Jan. 1, 2020, deadline.
The FAA first published its ADS-B rule in May 2010, as a significant step toward its Next Generation Air
