Airport coordinates updated in flight safety rules

The FAA updated the precise geographic coordinates for Essex County Airport in New Jersey within the airspace rules that govern flight safety zones around the airport. The rules themselves—what planes can do in these zones—didn't change, only the exact location data and a reference system were updated for accuracy and clarity.

This is administrative maintenance, not a structural change: coordinates drift over time due to surveying improvements, and reference documents get renamed or replaced, but these updates don't shift how aviation works or who can fly where.
