Effective 25 April 2019 NAV Canada has turned off the "YSH" NDB, and it will be removed from all aeronautical publications.
NAV CANADA recently completed an Aeronautical Study to determine the requirement for ground-based navigation aids across Canada. The study was sent to Transport Canada for review from a safety perspective in November 2017. As a result of the study, and with Transport Canada’s agreement, it has been determined that the “YSH” NDB services at the Smiths Falls airport were no longer required. Currently, the Smiths Falls airport is serviced by GNSS instrument approach procedures that allow access to the airport, and maintains the level of service required under the Canadian Air Navigation Services Commercialization Act.
A "Notice" detailing the changes will be posted on the NAV CANADA website at Service Notices
a minimum of 60 days prior to the 'turn off' date, and will complement an Aeronautical Information Circular that will be published a minimum of 28 days prior to the change.
Please refer to the NAV CANADA website at Navaids Project
to stay updated on the changes, monitor progress, and to view the Aeronautical Study.
