Summary

Commissioners were told the GCO unit at Grosse Ile has been decommissioned; the nearby non-directional beacon (NDB) removal is still in process and not yet reflected on charts or publications, and staff asked members to flag lingering website references.

Grosse Ile Airport and Commerce Park Commission members were told the ground communications outlet (GCO) has been decommissioned and that removal of the airport's non-directional beacon (NDB) has not yet been fully reflected on aeronautical charts or some online materials.

Jeff (commission member) led the follow-up discussion and asked whether the GCO and NDB had been removed from published sources and the airport website. Janelle (staff member) said the GCO "has" been fully decommissioned and that the NDB "is not fully decommissioned just yet" and may not appear on current charts.

Commissioners said transients had recently asked how to activate the GCO, suggesting outdated references still exist online. Janelle asked commissioners to email her if they find lingering website or handbook references so staff can remove or correct them.

Why it matters: lingering references to decommissioned navigation or communications equipment can confuse visiting pilots. Janelle noted a recent pilot who arrived on a Sunday and asked how to activate the GCO, and commissioners discussed removing outdated references from the airport's facilities handbook and web pages.

Next steps: staff will locate and remove references to the decommissioned GCO and follow up on the NDB removal status with affected charting and publication authorities; commissioners were asked to report any remaining references by email so staff can correct them.
