Newark Liberty and Philadelphia airports are currently experiencing a ground stop due to an air traffic control communication issue. The Federal Aviation Administration (FAA) has temporarily halted some incoming flights into Newark Liberty, Philadelphia, and Teterboro, New Jersey airports.
The problem is connected to specific frequencies at a Philadelphia air traffic control facility. According to FlightAware, a flight tracking website, more than 300 flights at Newark and Philadelphia, representing about 15% of flights, have been delayed.
The FAA ordered the ground stop around 10 a.m. Monday, with an initial duration until at least 12:45 p.m. A spokesperson stated, "The FAA is pausing flights into Philadelphia International, Teterboro and Newark Liberty International airports due to issues with some frequencies at Philadelphia TRACON." TRACON refers to Terminal Radar Approach Control, an air traffic control facility.
