What are the three types of temporary flight restrictions?

The FAA issues TFRs under three sections of FAR Part 91: disaster TFRs (91.137) for wildfires and emergencies, VIP TFRs (91.141) for the President and other officials, and security TFRs (91.145) for sensitive facilities and public events over 30,000 attendees. Each type has different dimensions, rules, and any applicable exceptions.

Where is the best place to check for active TFRs before a flight?

The FAA's official TFR website at tfr.faa.gov shows a national map of all active and scheduled TFRs. Check it last before taxiing - not just when you file - because VIP TFRs can appear with very short notice. Your EFB is a useful visual backup but must have a current data update to be reliable.

What should I do if I accidentally enter a TFR?

Do not turn and exit as fast as possible. Immediately contact ATC, identify yourself, state your position, and follow their instructions. Fly predictably - no rapid turns or descents. Filing an ASRS report within 10 days and before the FAA contacts you provides protection from certificate action for unintentional violations, but it only works once.

What is the DC SFRA and who needs to know about it?

The DC Special Flight Rules Area extends 30 nautical miles from Reagan National Airport and requires FAA Safety Team online training, a filed flight plan, a published SFRA route or ATC clearance, and an altitude-encoding transponder to operate in. Inside 15nm is the Flight Restricted Zone, which requires a TSA security threat assessment in addition to all SFRA requirements. Any pilot flying on the East Coast should have a working understanding of this airspace.

The Temporary Flight Restriction, the Three Types That Aren't the Same, and the Preflight Step That Has to Come Before You Push the Throttle

Temporary flight restrictions (TFRs) live in the same NOTAM package as taxiway closures and lighting outages, but they carry consequences that minor procedural notices do not. Three distinct regulatory types exist under FAR Part 91, and the rules inside each one - including any legal exceptions - are not interchangeable. Treating them all as generic stay-out zones is how pilots end up talking to Center with cold hands forty miles from home.

What Is a Temporary Flight Restriction?

The FAA uses TFRs to protect a specific area of airspace from aircraft operations for a defined period of time. They are issued under FAR Part 91 and published in the NOTAM system under the FDC (Flight Data Center) category. FDC NOTAMs carry regulatory changes and flight restrictions - any reference to 91.137, 91.141, or 91.145 in the package means a TFR is present and requires a full read.

The authoritative visual reference for all active and scheduled TFRs is tfr.faa.gov. It displays a national map with clickable entries showing full details for each restriction. It takes about 60 seconds and belongs at the start of every preflight briefing.

What Are the Three Types of TFRs?

Disaster TFRs - FAR 91.137

Disaster TFRs protect airspace around wildfires, chemical spills, earthquake zones, and other major natural disasters. The primary purpose is to keep the airspace clear for aerial firefighting operations, damage assessment aircraft, and emergency response helicopters.

FAR 91.137 has three tiers. The first tier protects active rescue and firefighting operations. The second adds damage assessment. The third addresses news media access and includes a defined exception for aircraft coordinating with a designated news media point of contact. Radius and altitude floor vary by event - a 3 nautical mile ring or a 10 nautical mile ring is common, with a floor frequently set at 2,000 feet AGL. Read the actual NOTAM before assuming any specific dimensions.

The operational reality near an active wildfire: air tankers and lead planes work at low altitude and high speed, focused on the drop rather than traffic separation. Scooper aircraft hit mountain lakes and turn immediately. If smoke is detectable from the cockpit, assume the airspace ahead contains fast-moving aircraft that may not be reachable on any available frequency.

VIP TFRs - FAR 91.141

VIP TFRs go up around the President, Vice President, and other designated officials when security requirements call for it. They typically come in two concentric rings - an outer ring, often 30 nautical miles, and an inner ring, often 10 nautical miles.

The rules differ between rings. Inside the inner ring, the restriction is essentially absolute for uncoordinated general aviation. Inside the outer ring, IFR operations on an active instrument flight plan are permitted. VFR operations require a discrete transponder code, an operable altitude-encoding transponder, and two-way communication with ATC.

The critical characteristic of the VIP TFR is that it can move. If the President is aboard Air Force One, the TFR moves with the aircraft. These NOTAMs are also frequently issued with short notice - a route that was clean the night before can have a TFR sitting across it by the time you’re in the runup area. Checking tfr.faa.gov should be one of the last steps before taxiing, not one of the first when filing.

Military intercepts for TFR violations are not hypothetical. The procedures are in the Aeronautical Information Manual: the intercepting aircraft rocks its wings; you acknowledge by rocking yours. They turn; you follow. Immediately attempt radio contact on guard frequency 121.5 MHz and land where directed.

Security TFRs - FAR 91.145

Security TFRs cover sensitive government installations and regularly scheduled public events. Under FAR 91.145, any outdoor event with attendance over 30,000 people generates a 3 nautical mile, 3,000-foot TFR from one hour before the event begins to one hour after it ends.

The stadium TFR appears at every home game for every major professional venue in the country. It is predictable, and it is easy to forget. If you’re flying near a metro area on a fall Sunday afternoon, check the schedule before you file.

Security TFRs around national infrastructure can be standing restrictions or rotating ones. Make sure your EFB (electronic flight bag) is configured to display TFRs - ForeFlight and Garmin Pilot both show them as a red shaded overlay. When zoomed in on the departure airport, a TFR 40 miles out can disappear into visual noise.

How Do You Find TFRs in a NOTAM Package?

The disciplined approach doesn’t require much time, just a consistent sequence:

Before opening the NOTAM package, go to tfr.faa.gov. Review the national map, click anything near your route, and read the details. This takes roughly 60 seconds.
When working through the NOTAM package, filter for FDC NOTAMs. These carry regulatory changes, flight restrictions, and approach amendments - TFRs live here.
Any FDC NOTAM referencing 91.137, 91.141, or 91.145 gets a full read, not a skim.
Pull a fresh EFB data update close to departure, not two hours earlier. EFBs are a backup to the preflight briefing, not a replacement for it.

What Happens If You Violate a TFR?

The FAA treats TFR violations more seriously than most other airspace incursions. A VIP TFR violation can trigger a multi-agency response involving the FAA, TSA, and the military - potentially before anyone asks questions on the ground.

Filing an Aviation Safety Report through the NASA Aviation Safety Reporting System (ASRS) provides some protection from certificate action. Filing must occur within 10 days of the violation and before the FAA contacts you. It applies only to unintentional violations, works only once, and does not protect against criminal charges if the violation rises to that level.

The ACS answer on inadvertent restricted airspace entry: do not turn and run. Immediately contact ATC, identify yourself, state your position and situation, and follow instructions. Fly predictably. No rapid turns. No rapid descents. Get on a frequency and talk.

What Is the Washington DC Airspace, and Why Does It Matter?

The DC Special Flight Rules Area (SFRA) extends 30 nautical miles from Ronald Reagan Washington National Airport. Operating anywhere within the SFRA requires completing the FAA Safety Team DC SFRA online training course, filing a flight plan, flying a published SFRA route or holding an ATC clearance, and carrying an altitude-reporting transponder.

Inside 15 nautical miles is the Flight Restricted Zone (FRZ) - the most restrictive civilian airspace in the country. Entry as a general aviation aircraft requires a security threat assessment from the TSA, authorization through Reagan TRACON, a filed flight plan, an altitude-encoding transponder, and two-way communication. It is not sightseeing airspace.

Pilots based in Virginia, Maryland, Delaware, or anywhere near the DC metro area must treat this as foundational knowledge, not optional reading.

What Should You Do Before Your Next Flight?

Pull up the sectional for your home area and look at everything within 60 nautical miles in all directions. Identify restricted areas, Military Operations Areas, sporting venues, and sensitive facilities. Understanding local airspace geography before it matters under pressure is the difference between catching a problem in the runup area and catching it from Center at cruise altitude.

The preflight is not finished when the weather check is complete. It is finished when the airspace between you and your destination is specifically, currently confirmed to be what you expect it to be.

Key Takeaways

Three distinct TFR types exist under FAR Part 91 - disaster (91.137), VIP (91.141), and security (91.145) - and their rules, dimensions, and exceptions differ.
tfr.faa.gov is the authoritative national display; check it last before taxiing, not first when filing.
VIP TFRs can appear with short notice and move in flight - a clean briefing from the night before is not a clean briefing.
Stadium TFRs are predictable: 3nm/3,000ft, from 1 hour before to 1 hour after, for any event exceeding 30,000 attendees.
If you inadvertently enter restricted airspace, contact ATC immediately, fly predictably, and follow instructions. Filing an ASRS report within 10 days and before FAA contact provides enforcement protection for unintentional violations.
