Drone TFRs: How FPV Pilots Check No-Fly Zones Before Flying

The new southern border drone TFR is a long corridor along the whole boundary, not a circle around one site, and it covers the altitudes where FPV pilots fly. Here is a preflight routine that catches it and every other TFR.

On October 16, 2026 the FAA, together with the Department of Transportation, the Department of War and the Department of Homeland Security, put a new temporary flight restriction in place for drones along the U.S.-Mexico border. Some outlets still call the Department of War the Department of Defense. It is the same department.

The restriction matters to FPV pilots for two reasons. Its shape is unusual, and its altitude band covers nearly all recreational flying. It is also a good reason to tighten up how you check for TFRs in general. The routine below works for any TFR, and the border corridor runs through it as a worked example.

What the border TFR covers

The restricted area is a strip on the U.S. side of the line that extends one nautical mile north of the border. Vertically it runs from the ground up to a ceiling of 400 feet above ground level (AGL). Drone flights inside that block are banned unless they are authorized. Reporting on the announcement said it was effective immediately. That wording comes from a republished copy of the AVweb article, so check the original before you rely on the timing.

The government cited threats from cartel drones as the reason. In border cities such as El Paso, the strip of U.S. airspace right next to Mexico is now closed to drones without authorization. The FAA announcement and the matching DHS release are the primary sources.

Three details were not in the material behind this column: the NOTAM number, the end date and the exact boundary coordinates. The steps below show you how to get them yourself. That is a better habit than trusting a summary anyway.

Why this TFR breaks an old habit

Many pilots think of a TFR as a circle around a stadium, a VIP visit or a wildfire. If you check the area around your field and see no circle, you assume you are clear. The border TFR follows the full length of the international boundary as a line. A quick glance at a map centered somewhere else can miss it entirely if your spot is near the border.

The altitude band is the other problem. A ceiling of 400 ft AGL starting at the surface covers freestyle, bando sessions, racing gates and most long-range cruising. You cannot fly under or over this one in any practical way, so the only real question is whether you are inside the strip.

The preflight routine

1. Start with tfr.faa.gov

The FAA's Temporary Flight Restrictions list at tfr.faa.gov is the official source and is updated in real time. It lists TFRs for crewed and uncrewed aircraft alike. Do not filter it down to a few miles around your field. Scan the region, and open any entry that runs near your flying site or your planned route. For the border TFR, open the entry and read the full NOTAM text and graphic. That text is where you will find the details this column could not confirm.

The FAA also keeps a separate drone-specific TFR map on a different website. Rupprecht Law, an aviation law practice, recommends checking both.

2. Check NOTAMs directly

TFRs are published as NOTAMs. The FAA's NOTAM search at pilotweb.nas.faa.gov is linked from the same FAA site navigation as the TFR list. A second source helps if one site is slow or a graphic fails to load. You can also get a standard briefing from Flight Service at 1-800-WX-BRIEF.

3. Cross-check with a B4UFLY app

The old advice to download the FAA's own B4UFLY app is out of date. Since February 1, 2024, the FAA has delivered B4UFLY airspace information through several partner companies. Aloft Air Aware and AutoPylot are two of the approved apps. These apps are convenient in the field, where you may not want to read raw NOTAM text on a phone.

There is one caution. It was not confirmed that every approved B4UFLY app has already loaded the border TFR. Treat the app as a cross-check. If the app and tfr.faa.gov disagree, go with tfr.faa.gov.

4. Read the boundary, the altitudes and the times

For each TFR near you, answer three questions from the NOTAM:

• Where is the edge? For the border TFR, the edge is one nautical mile north of the border line. The exact coordinates are in the NOTAM itself. A nautical mile is longer than a statute mile, so do not eyeball it from a road map.
• What are the floor and ceiling? The border TFR starts at the surface and tops out at 400 ft AGL. AGL means the ceiling is measured from the ground below, not from sea level, so it follows the terrain.
• When is it active? Check the start and end times in the NOTAM. The border TFR has no end date in the sources used here, so confirm it before every session near the border.

If your planned flight path crosses the boundary at any point, you are inside the TFR. With long-range builds, think about where the quad could end up, not just where you plan to fly. A failsafe that carries the quad somewhere you did not intend is still your flight. If you rely on GPS Rescue, our GPS Rescue setup column covers how to configure it.

5. Find out how authorization works, if you need it

The ban covers unauthorized flights, which means some authorized flights are allowed. None of the sources used here explain how a drone pilot gets authorization to fly inside the border TFR. That process is normally spelled out in the NOTAM text, so read it there. Do not assume LAANC or DroneZone handles it.

6. Then, separately, check controlled airspace

Once you know you are clear of TFRs, you still need to know whether your site is in controlled airspace near an airport. That is a different question with a different tool.

TFRs are not LAANC

LAANC issues FAA airspace authorizations for drone flights below 400 feet in controlled airspace near airports. It is open to Part 107 pilots and to recreational flyers. Since February 20, 2023, recreational flyers have also been able to request near-real-time LAANC authorizations for night flying in controlled airspace.

LAANC does not authorize flight inside a security TFR. An app that tells you no LAANC authorization is needed has answered the controlled-airspace question only. It has not told you there is no TFR. Some companies do both jobs. Aloft, for example, publishes a B4UFLY app and is also an approved LAANC provider. That makes it easy to blur the two checks together, so keep them separate in your head.

Do not forget the standing stadium rule

One drone restriction does not show up as a new event TFR each time. A standing rule bans drones within 3 nautical miles of major stadium events from one hour before the event until one hour after. It covers MLB, NFL, NCAA Division I football and major motorsports. If your field is near a large venue, check the game schedule as well as the TFR list.

Make it part of the build-to-flight routine

Most FPV preflight checklists focus on the quad: props tight, failsafe tested, VTX on the right channel. Airspace belongs on the same list, ahead of arming. The Rules chapter of FPV Drone Essentials covers the FAA framework recreational pilots work within. Our Weight and Rules guide covers how a build's weight interacts with those rules.

A practical order that takes a couple of minutes:

1. Open tfr.faa.gov and scan the region, not just your field.
2. Open and read any NOTAM near your site or route, including floor, ceiling and times.
3. Confirm on a second source: the NOTAM search, a Flight Service briefing or a B4UFLY app.
4. Check the drone-specific TFR map.
5. Check for stadium events within 3 nautical miles.
6. Check controlled airspace and request LAANC if you need it.

If you fly anywhere near the southern border, run step 1 every time. A corridor that follows the whole boundary is easy to miss if you only look at the area around your own spot. For the broader policy picture behind restrictions like this one, see our counter-drone policy guide.
