Taking the Mystery Out of Temporary Flight Restrictions

By James Williams

Since Temporary Flight Restrictions (TFRs) are a fact of life for today’s pilots, it was clear that the topic had to be included in an issue devoted to the National Airspace System (NAS) and air traffic control. But, rather than repeat the tried, true, and admittedly tired explanations of what constitutes a TFR, we decided to focus instead on another angle: who constitutes a TFR, and how do they decide to establish such restrictions.

Even though I work for the FAA, I confess I started with the notion that “they” must be evil men and women in dark capes and masks, intent on curbing our fun in the sky. I set up an interview and, at the appointed time, walked through the doorway.

Imagine my surprise to be greeted by life-sized statues of Jake and Elwood Blues, denizens of the classic 80s comedy “The Blues Brothers.” I first assumed it was just an unexpected spark of quirky personalization in an otherwise drab government office. But, after speaking with members of the staff, I realized the statues were strangely appropriate. If you’ve seen the film, you might recall that Jake and Elwood Blues repeatedly insist that “We’re on a mission from God.” While no one in the Office of System Operations Security lays claim to a divine mandate, it is nonetheless clear that they have a strong sense of mission.

“We are truly GA’s last advocate,” says Frank Hatfield, director of System Operations Security. His office has the responsibility to work closely with various national and regional security agencies and organizations and determine how best to balance security requirements with the public’s need for access to airspace. It’s not an easy job. Hatfield and his staff face a daily challenge to balance very real security needs with the GA community’s equally real need for access to the NAS.

For better understanding of how the TFR process works, I sat down with Brian Throop, Darrell Hood, and Rick Hostetler. “The main things we work in this shop are the Presidential and National Special Security Event (SSE)-type TFRs,” Throop explains. “Darrell is our Homeland Security and law enforcement program manager, and so he works with the Secret Service on a regular basis to design and negotiate the airspace involved in VIP movements.”

It’s All about Balance

“Our overarching goal is balance,” Throop continues. “We get requests from our law enforcement partners or security partners who say ‘we need a TFR over X event’. We look at that request from an impact standpoint and coordinate with our local facilities. We try to apply an air traffic control or FAA filters to [the request]. If the initial request was 60 miles, could they work with 58? Could they start the TFR 10 minutes later? Could we get a cut-out area for this airport on the fringe? Our work is all about the many details and considerations involved in trying to lessen the impact on airspace users.”

There is no question about the reality of security concerns. “We get a lot of requests for TFRs,” Throop observes. “GA pilots may feel like TFRs pop up everywhere, but the number they actually see is probably only a tenth of the total requests. We get requests from virtually every police department, city council, mayor, or town manager with an event that they think merits a TFR.”

Happily for GA pilots, most requests simply do not meet the System Operations Security Office’s criteria. The staff starts by reviewing the potential threat against the benefit of a free and open society. As Throop stresses, though, the FAA does not make this decision in a vacuum. “We go to our contacts at TSA and FBI, and we ask if they have credible threat information about the event in question. They reach out to their field offices and, in most cases, the answer is no. So we go back to the requesting organization and explain that the event doesn’t meet our requirements for shutting down the airspace. On those rare occasions when TSA or FBI contacts do say that there is credible threat, we establish a TFR. But once we agree to the TFR, our priority becomes determining how quickly can we take it down and restore access to the airspace.”

Throop and his colleagues also stress that their advocacy is not confined to larger airports. “If there are pilots out there with a Maule or a Cessna with tundra tires taking off from a grass strip on their 250 acre farm, they have a need to use the airspace. So we advocate for that.” Throop says. “We will do everything we can to get them in the air. We never, ever dismiss a restriction as ‘well, it’s just one person or just one airport.’ Those people have an absolute right to access the airspace as much as possible.”

Getting the Word Out

In addition to getting TFRs in place, the System Operations Security Office also has the challenge of notifying the pilot community in a timely way, explains Darrell Hood, Homeland Security/law enforcement liaison. An example the staff aims to avoid repeating is the TFR established in Hawaii during the President’s vacations.

In 2009, the President’s visit to Hawaii virtually shut down much of the GA activity in the islands. For 2010, we worked with the General Aviation Council of Hawaii and the Secret Service to allow a lot more activity without compromising security,” says Hood. “We’re really proud of that.”

I asked Hood what kind of flexibility the FAA has when it comes to issuing or denying a TFR. The answer: It depends. In some cases, legal requirements leave little, if any, flexibility. Short of that, though, the FAA tries to balance the competing and often conflicting needs of security and access.

“The threat is probably the most important thing we look at,” notes Hood. “Is there a threat to either those in attendance, or to the event itself? Then we make a determination based on our analysis, along with input from law enforcement agencies, FBI, TSA, and Secret Service. They all have opinions, and they all have input. But then we make a decision.”

Though it may not always appear this way to pilots looking at a TFR in their home airspace, Hood stresses the mission: “The FAA’s mandate is free access to the airspace, so we try to honor that mandate on every request.”

Rick Hostetler, manager of Classified Operations, gave me a good example of an instance when the FAA declined to act on a request for a TFR. “Last spring, the Masters was the first big golf tournament Tiger Woods played after his personal difficulties. The Masters Tournament organizers wanted a TFR over Augusta because they were concerned about aircraft flying over for curiosity and press. As we saw it, though, the request did not meet our primary criteria. There was no credible threat, so we denied their request for a TFR. More often than not, that’s how TFR requests are answered.”


When it comes to letting pilots know about TFRs, Hostetler explains that his office works very closely with pilot organizations. Still, it’s a challenge. “There were six violators for the Super Bowl in Dallas. Not one of the violators knew there was a Notice to Airmen (NOTAM) for the Super Bowl because they didn’t check the NOTAMs,” Hostetler says. “All the flights involved originated within 40 miles of the game and five of them actually originated inside the TFR. Despite all of the media coverage and all the outreach we did, we still had six violators.” The goal of course, although an elusive one, is to have no TFR violations.

As I passed the Blues Brothers statues on my way out of the System Operations Security Office, I did feel better about GA’s position in today’s new world of security restrictions. There really are people out there—or rather, in this very building—advocating for GA. They may not win on every decision, but they are on our side, fighting every day to make sure our needs for access to the NAS are not only considered, but advocated and protected. Like the film’s protagonists, this small office keeps on going despite the enormity of the task and the difficulty of the odds. They do it without much recognition and with no fanfare. But, as it turns out, they may well be the best friend GA has in its ongoing struggle to safeguard access to the NAS.

My final question: What would you like the GA world to know? “I’d like GA pilots to know one thing,” Hood says. “We are their advocate for access to the airspace. But I’d also like to make a request: PLEASE, please check NOTAMs.”
