A retired air traffic controller said it's safe to fly out of Newark Liberty International Airport but stressed that building a larger workforce is the bigger challenge.Why It MattersNewark Airport, under the auspices of the Port Authority of New York and New Jersey, has made national headlines over the past week because of drastic increases in flight delays and cancellations for reasons including staffing shortages and inclement weather.What To KnowRetired Federal Aviation Administration (FAA) air traffic controller Harvey Scolnick told CNN This Morning anchor Audie Cornish on Tuesday that he has "no problem whatsoever" flying out of Newark, calling the airspace "safe.""I still think they have a staffing problem," Scolnick said. "They're talking about hiring 2,000 controllers next year. They may have to hire double that, or maybe 5,000. That is the issue."Controllers want time off. It's difficult to get time off. They're working mandatory six-day weeks. The fact that controllers are now required to have extra time off in between shifts makes it more difficult to swap. I honestly think that controllers are overworked and don't see any light at the end of the tunnel."The federal government is being more aggressive in "supercharging" air traffic controller hires to boost the airspace and, in turn, bolstering safety while reducing disrupted flights.That has included a multi-faceted campaign set forth by Transportation Secretary Sean Duffy and the FAA to provide potential new air traffic controller hires with higher base salaries and swifter hiring times.The government's plan includes hiring at least 2,000 controllers this year, which they say can be accomplished by streamlining the hiring process from its former routine eight-step process to a five-step process—which the FAA said has already shaved five months off wait times and allowed more than 8,300 candidates to take the aptitude exam, or Air Traffic Skills Assessment (ATSA).The approximate median annual wage for air traffic control specialists is $127,805, according to FAA data. Salaries for entry-level air traffic control specialists increase as they complete each new training phase.An agreement between the FAA and National Air Traffic Controllers Association (NATCA) also provides incentives for potential applicants, including a $5,000 reward for new hires who successfully complete the initial qualification training and a $10,000 award for Academy graduates who are assigned to one of 13 hard-to-staff air traffic facilities.Scolnick acknowledged that being an air traffic controller is "a high-pressure job" that requires quick decisions and adjustments in the heat of the moment. The situation involving Newark is not necessarily a surprise, he added."Now, these controllers at Newark, many of them are unhappy to begin with," he said. "They were, about a year ago, working at a facility in Westbury, Long Island, and suddenly they found themselves working at a facility at the Philadelphia airport. So, they're not too happy to begin with because they've had to relocate."In addition, they are short-staffed. And that seems to be the problem at the FAA right now. The FAA for years, as I can recall, in the busier facilities, has always operated short of the required number of fully certified controllers that were programmed for those facilities."What People Are SayingAn NATCA spokesperson told Newsweek: "The dedicated, American, hard-working employees who serve as controllers are the foundation of our air traffic control system. These controllers and the thousands of other aviation safety professionals represented by NATCA ensure the safe and efficient movement of millions of passengers and tons of cargo through our dynamic airspace every day. These professionals ensure the safe movement of aircraft through the National Airspace System as a primary goal."An FAA spokesperson told Newsweek: "Our antiquated air traffic control system is affecting our workforce. We must get the best safety technology in the hands of controllers as soon as possible. We are working to ensure the current telecommunications equipment is more reliable in the New York area by establishing a more resilient and redundant configuration with the local exchange carriers. In addition, we are updating our automation system to improve resiliency."What Happens NextAir travelers hoping for a reprieve on Tuesday at Newark were disappointed. As of 12:15 p.m. ET, 194 flights into or out of Newark had been delayed and 100 had been canceled, according to flight tracker FlightAware.
