Two local airports will have to cease operations on days when the president is visiting his club in Bedminster.
Jodi DiPane-Saleem still remembers the day she looked up and saw two fighter jets circling her small rural airport.
Turns out they were escorting a wayward pilot who had strayed into a presidential security no-fly zone while the United Nations was in session.
So she knows first-hand: When the President of the United States is in town, airspace security is for real.
The Federal Aviation Administration issued an updated Temporary Flight Restriction notice Tuesday for May 4-7, classifying the airspace over Trump National Golf Club in Bedminster as "national defense airspace."
That mans Donald Trump's upcoming visit this weekend will likely bring traffic to a stop at the two local airports unlucky enough to fall within a ten-mile security ring: Somerset Airport in Bedminister and Solberg Airport in Readington.
That ring cuts right through the center of DiPane-Saleem's facility, Central Jersey Airport in Hillsborough, but fortunately the U.S. Secret Service advance men decided to list the facility as being outside the ring, said Di-Pane Saleem.
"If we were not pulled out of that ring, we couldn't fly at all. We'd be completely grounded, " said DiPane-Saleem. "It would've killed us. We were really happy that they were willing to accommodate us and work with us."
The Temporary Flight Notice bans all flights in or out of a 10-mile radius of Trump National for the duration of the president's visit. That ban exists even if the president arrives at his property by car, as is expected this weekend.
Regularly scheduled commercial flights can fly over the ring, as can emergency ambulance, police, or firefighting flights that have requested permission.
Banned completely are take-offs and landings, including flight lessons, seaplanes, gliders, hang-gliding, crop-dusting, balloons, banner-towing, model aircraft and unmanned aircrafts from the two airports inside the zone.
Thor Solberg, Jr. of Solberg Airport in Readington Township in Hunterdon County said he's concerned Trump will make frequent weekend jaunts to New Jersey this summer.
The airport does about 60 percent of its business during the summer, and about 60 percent of that is on the weekends. The Secret Service has not been flexible about the need for a full shutdown during presidential visits, he said.
However, he said he was hopeful the airport's signature summer event, the QuickChek New Jersey Festival of Ballooning, would be allowed to proceed even if the president were in town.
"The Secret Service understands you can't drive a balloon in the direction you want it to go," Solberg said, explaining a balloon pilot could not intentionally fly a balloon in the direction of Trump National.
Russ Mensch, spokesperson for the July 28-30 festival, said it will go ahead as planned, even if Trump's in town that weekend. Executives from the festival, who met with the FAA in March, received a pledge from FAA representatives "develop and execute a good security plan that will ensure the balloon festival will go on as planned."
Although Central Jersey Airport is outside the 10-mile ring, DiPane-Saleem is worried about an upcoming Armed Forces Appreciation Day scheduled at her facility for May 20th.
The show includes antique and military planes of all kinds, all flown in by private owners. "It's a big event, and if they can't get in when Trump's here, my event is shot," she said.
The Secret Service has been mindful of the importance of community charity events, she said, and told her, "We don't want to be the enemy."
Presidential visits are disruptive to local air traffic no matter where they occur - whether West Palm Beach, where recreational pilots were grounded nearly every weekend, or Martha's Vineyard, where Obama family vacations would bring charter flights to a halt.
Small airports make their money from flight lessons, charter flights, banner-towing businesses, and recreational pilots - all of which could be impacted by a summer of Temporary Flight Rules.
Somerset Airport has already been in consultation with neighboring Central Jersey Airport to see if it could run some of its operations out of that facility, DiPane-Saleem said.
Pilots caught violating the protected airspace can be fined or lose their piloting license. Accidentally straying into a no-fly zone through inattention is less likely than it used to be, said DiPane-Saleem.
That's because pilots use navigational software that displays the 10-mile ring in real time - much the way commuters get real-time information about traffic jams on a GPS.
At Somerset Airport, they've been preparing for Trump summer visits by giving their pilots a cheat sheet on what to do if they are intercepted by NORAD fighters.
Pilots should acknowledge the fighter's presence with a "wing rock," it advises, and at all times "remain predictable."
