Temporary Flight Restrictions (TFRs)

14.temporary-flight-restrictions. Temporary Flight Restrictions (TFRs)

A Temporary Flight Restriction (TFR) is a regulatory action issued by the FAA via Notice to Air Missions (NOTAM) that defines a specific area of airspace in which the operation of aircraft is temporarily restricted, prohibited, or limited. TFRs are not a class of airspace, but they overlay existing airspace and carry the force of regulation. Violating a TFR can result in certificate suspension, civil penalty, or — in the case of security TFRs — interception by military aircraft.

Purpose of TFRs

TFRs are established to:

• Protect persons and property in the air or on the surface from an existing or imminent hazard.
• Provide a safe environment for disaster relief, firefighting, or law enforcement operations.
• Prevent unsafe congestion of sightseeing aircraft above an incident or event.
• Protect the President, Vice President, and other public figures.
• Protect declared national disasters or events of national significance (e.g., space launches, major sporting events).

Regulatory Basis

TFRs are issued under several Federal Aviation Regulations, each tailored to a specific purpose:

• 14 CFR 91.137 — Disaster/hazard areas (wildfires, chemical spills, floods).
• 14 CFR 91.138 — National disaster areas in Hawaii.
• 14 CFR 91.139 — Emergency air traffic rules.
• 14 CFR 91.141 — Flights in proximity of the President and other parties.
• 14 CFR 91.143 — Flight limitations in proximity of space flight operations.
• 14 CFR 91.145 — Management of aircraft operations in the vicinity of aerial demonstrations and major sporting events.

The specific FAR cited in the NOTAM dictates exactly who may operate inside the TFR and under what conditions.

Typical TFR Structure

Most TFRs are described as a cylinder or stadium-shaped volume defined by:

• A center point (latitude/longitude or a VOR radial/DME).
• A radius in nautical miles (commonly 3 NM, 10 NM, or 30 NM).
• A vertical limit, almost always expressed in feet MSL (e.g., "surface up to and including 17,999 feet MSL").
• Effective times in UTC (Z).

Presidential TFRs (91.141) typically combine a 10 NM inner core (no flight permitted except under specific waiver) with a 30 NM outer ring (transient IFR or VFR operations to/from airports under tight conditions, with an active discrete transponder code and ATC two-way communication). Stadium TFRs under 91.145 are usually a 3 NM radius up to 3,000 feet AGL, in effect from one hour before through one hour after the event for stadiums seating 30,000 or more.

Pilot Responsibilities

Under 14 CFR 91.103, a pilot in command must become familiar with all available information concerning the flight before departure — including any TFRs along the route. This is not optional. Practical steps:

1. Check graphical TFRs at tfr.faa.gov before every flight.
2. Review the NOTAM text (not just the graphic) to confirm coordinates, altitudes, times, and exceptions.
3. Use a current EFB (ForeFlight, Garmin Pilot, etc.) with TFRs loaded — but verify against the FAA source.
4. During flight, monitor Flight Service on 122.2 or contact ATC for pop-up TFRs, which can be issued with little notice (e.g., wildfire response).
5. If transiting near a TFR, request flight following so ATC can warn you of penetration.

Common Exceptions

The NOTAM lists who is exempt. Typical examples:

• Aircraft participating in disaster relief, firefighting, or law enforcement operations under ATC direction.
• Scheduled commercial passenger and cargo flights operating IFR.
• Aircraft arriving or departing local airports may be permitted under specific procedures, but only as spelled out in the NOTAM — never assumed.

Example

A wildfire TFR might read: "Aircraft operations within an area defined as 5 NM radius of 39°15'N 120°50'W, surface up to and including 10,000 feet MSL, effective 1500Z 15 JUL until 0300Z 16 JUL, are prohibited except aircraft operating under direction of the Incident Commander on frequency 123.45." A non-participating pilot must remain clear laterally and vertically.

Consequences of Violation

Incursions are tracked by ATC radar and, near security TFRs, by military and DHS assets. Penalties range from administrative action and certificate suspension (typically 30–90 days for a first offense) to permanent revocation. Security TFR busts in the Washington, DC SFRA/FRZ may result in fighter intercept, forced landing, and federal investigation. There is no "I didn't see the NOTAM" defense — pre-flight planning is the regulation.
