Dear AMA Members,

If you fly at an AMA field that’s part of the national altitude extension in Class G airspace released in April of 2025, there are important rules you need to follow—especially when flying above 400 feet. These guidelines help our fields to continue to operate safely and legally under the FAA authorization so future modelers can enjoy the extensions as well.

Here’s what you need to know before flying:

All pilots must:

•    Follow USC 44809 and AMA Safety Guidelines: You need to be aware of and follow all AMA safety code practices, USC 44809, and any rules that apply specifically to the flying site in question. 
•    Be Aware of Nearby Aviation Activity: Clubs should be aware if their field is within 2 nautical miles of charted, manned air traffic (such as small airports) and inform you of any safety mitigations or site-specific rules you need to follow in case of possible aircraft nearby. The increased altitudes do not constitute waivers from any other law or safety rule. See the FAQ link for documentation requirements.
•    Know Site-Specific Limits: Some sites have altitude or area restrictions based on their size or location. This might change during an event vs. daily flying if the local leadership feels it is necessary or is required by a separate local agreement. Remember, even if a field has received 700-foot or 1,200-foot above-ground-level (AGL) clearance, the club might have restrictions on when they allow pilots to utilize the space above 400 feet. Ask before you fly. 
•    Understand the National Authorization: Especially if you don’t regularly fly at a field covered by this authorization, you might not be familiar with all stipulations. Make sure you read through the authorization and seek guidance from local club leadership if you don’t understand a section. AMA and District leadership will be available for questions as well, but local restrictions could apply, and club leaders should advise members prior to operation. 
•    Be FAA Registered: Make sure you’ve registered with the FAA as a recreational flier if operating UAS above 250 grams or 0.55 pounds and are following registration requirements. 
•    Have Completed the The Recreational UAS Safety Test (TRUST): The FAA requires all recreational drone and model aircraft pilots to pass the TRUST safety test. If you haven’t done this yet, it’s quick and free to complete on AMA’s website. 
Other Items About These Sites: 
•    Flying Above 400 Feet Is Only Allowed During the Day: The altitude extension only applies between civil sunrise and civil sunset. If you’re flying at night, you must stay at or below 400 feet AGL unless otherwise specifically authorized. 
•    Fixed Sites, Not All Class G: This authorization applies to registered AMA sites within Class G airspace that have been submitted for review; it does not authorize altitude extensions for all modelers in Class G airspace. Members can easily view approved sites on the FAQ page.
•    You Must Always Stay Within Visual Line of Sight: You or your spotter need to be able to see your aircraft clearly with your own eyes. 
•    Operations Must Follow the Weather Rules: If operating during an event at an applicable site, look to your event managers, contest directors, and FAA national altitude extension for guidance on weather and visibility conditions. 
•    NOTAMS: A NOTAM must be issued for any AMA Sanctioned Event in Class G airspace when flying above 400 feet AGL.

If you have questions not addressed here or in our FAQ page, AMA District Vice Presidents, Leader Members, your club leadership, and AMA Headquarters can provide further guidance. 
Please take the necessary steps to disseminate this information through your usual communication channels, including club meetings, newsletters, websites, and any other relevant platforms. 
Please encourage all AMA members to review the official National Altitude Authorization Briefing Blog Post.
