Newark problems and recent crashes put focus on air traffic controller shortage and aging equipment

The recent chronic delays and cancellations at New Jersey’s largest airport have highlighted the shortage of air traffic controllers and the aging equipment they use, which President Donald Trump’s administration wants to replace.

The Federal Aviation Administration is working on a short-term fix to the problems at the Newark airport that includes technical repairs and cutting flights to keep traffic manageable while dealing with a shortage of controllers. Officials are meeting with all the airlines that fly out of Newark starting Wednesday to discuss the plan.

But even before those problems, aviation was already in the spotlight ever since the deadly midair collision of a passenger jet and a U.S. Army helicopter above Washington, D.C., in January, and a string of other crashes and mishaps since then. The investigations into those crashes continue while the U.S. Department of Transportation tries to make progress on the long-standing issues of not having enough air traffic controllers and relying on outdated equipment. A U.S. Senate hearing Wednesday morning will focus on the FAA’s efforts.

Twice in the past two-and-a-half weeks, the radar and communications systems that air traffic controllers in Philadelphia who direct planes in and out of Newark rely on failed for a short time. That happened because the lines that carry the radar signal down from another FAA facility in New York failed, and the backup system didn’t work immediately.

So the controllers were left unable to see or talk to the planes around Newark Liberty International Airport for as long as 90 seconds on April 28 and May 9. The lines — some of which were old copper wires — failed a third time on Sunday, but that time the backup system worked and the radar stayed online.

But the first one of those stressful situations prompted five to seven controllers to take a 45-day trauma leave, and that worsened the existing staff shortage at the Philadelphia control facility, prompting the FAA to limit the number of flights in Newark each day.

The FAA currently has 22 fully certified air traffic controllers and five supervisors assigned to Newark in the Philadelphia facility, but the agency wants to have 38 controllers there. Another 21 controllers are in training there, and 10 of them are certified on at least part of the area.

The FAA quickly limited the number of flights in Newark to between 24 and 28 arrivals and the same number of departures every hour to make sure the remaining controllers…
