## Summary

The FAA is updating the Class E airspace around Pontiac, Illinois because the old radio navigation system (VOR) was turned off. They’re also fixing the airport’s location info to keep everything accurate and safe for pilots flying by instruments. These changes kick in on April 17, 2025, and won’t cost anyone extra—just smoother skies ahead!

## Abstract

This action amends the Class E airspace at Pontiac, IL. This action is the result of an airspace review conducted due to the decommissioning of the Pontiac very high frequency omnidirectional range (VOR) as part of the VOR Minimum Operational Network (MON) Program. The geographic coordinates of the airport are also being updated to coincide with the FAA's aeronautical database. This action brings the airspace into compliance with FAA orders and supports instrument flight rule (IFR) procedures and operations.
