Operations Over People Explained: Categories 1–4
Since April 2021, most operations over people no longer require a Part 107 waiver — instead, they fall into one of four categories based on aircraft weight and injury risk. Understanding which category applies to your aircraft is the difference between legal operation and a regulatory violation. Here's the plain-English breakdown for 2026.
Why categories exist
Historical Part 107 prohibited flight over any person not directly participating in the operation, with waivers as the only exception. The 2021 rule change replaced that blanket prohibition with a risk-based framework: the smaller and less dangerous the aircraft, the more permissive the operations allowed. Four categories with progressively higher risk thresholds and more demanding compliance requirements.
The category is a property of the aircraft configuration, not the operator. An operator who wants to fly over people determines which category their specific aircraft (with specific payload and configuration) fits and complies with that category's requirements.
Category 1 — the small-drone category
What qualifies: aircraft under 0.55 lb (250g) with no exposed rotating parts capable of laceration.
What's allowed: operation over people, including over open-air assemblies of people, without any waiver, provided the pilot complies with all other Part 107 rules. The most permissive category.
What "no exposed rotating parts capable of laceration" means: propeller guards or ducted-fan designs typically qualify. Bare props on standard consumer sub-250g quadcopters generally do qualify — the FAA has taken the position that most small propellers on lightweight aircraft don't produce laceration injuries during the kinetic-energy limits of Category 1.
Most sub-250g consumer aircraft (DJI Mini series, HoverAir X1 series, Autel Nano before discontinuation, Potensic Atom 2) qualify for Category 1 in stock configuration. Adding heavy payloads that push the aircraft over 250g takes it out of Category 1.
Category 2 — larger aircraft with proven low kinetic energy
What qualifies: aircraft that, in a maximum-transferable kinetic energy test conducted by the manufacturer, don't cause more than 11 ft-lb of energy transfer upon impact with a person. The aircraft must also have no exposed rotating parts capable of laceration and must not contain safety defects.
What's allowed: operation over people, but not over open-air assemblies of people (concerts, sporting events, protests, marches) unless the assembly has been notified and is directly participating.
The Means of Compliance (MoC): the manufacturer must have declared compliance with the Category 2 kinetic energy limit through a Means of Compliance accepted by the FAA. This puts the burden on the aircraft manufacturer, not the operator. In practice, few consumer aircraft above 250g have completed Category 2 declaration.
Category 3 — larger aircraft, restricted operations
What qualifies: aircraft that meet a 25 ft-lb maximum kinetic energy standard (higher than Category 2), with no exposed rotating parts capable of laceration and no safety defects.
What's allowed: operation over people only in limited circumstances — over people who are inside a closed or restricted-access site, OR over a specific person or persons who have received sufficient notification.
The Means of Compliance: same MoC declaration process as Category 2, but at the higher energy limit. Category 3 covers most professional inspection drones that are too heavy for Category 2 but need to operate around people at industrial or restricted-access sites.
Category 4 — airworthiness-certified aircraft
What qualifies: aircraft that hold an FAA airworthiness certificate (Type Certification under 14 CFR Part 21) issued specifically for operation over people. This is a fundamentally different (and much more demanding) regulatory path than Categories 1–3.
What's allowed: operation over people including open-air assemblies, subject to the aircraft's specific type certification conditions.
Practical reality: Category 4 is enterprise-only. Type certification is a multi-year, multi-million-dollar process. As of 2026, a handful of specialized delivery and public-safety aircraft have achieved it. No standard consumer or prosumer aircraft qualifies.
Sustained flight over open-air assemblies
Category 1 permits sustained flight over open-air assemblies. Categories 2 and 3 do not (with limited exceptions). Category 4 does, subject to type certification conditions.
"Sustained flight" is not defined by specific duration — the FAA interprets it as any flight where the aircraft passes over the assembly with the purpose of remaining over it, as opposed to incidental transit at altitude. For most sub-250g consumer operations, this is the practical distinction between "flew across a park" (probably fine) and "hovered over a concert" (Category 1 sustained operation, still allowed if the aircraft qualifies).
Category 1-eligible aircraft — the practical list for 2026
The consumer sub-250g aircraft that ship in configurations qualifying for Category 1 in stock form:
- DJI Mini 4 Pro, DJI Mini 5 Pro (existing US retailer stock while it lasts)
- DJI Neo
- HoverAir X1 Pro Max
- HoverAir Aqua (waterproof, launched 2025)
- Potensic Atom 2
Adding heavy payloads (large ND filter sets, external strobes, tracker devices) can push the aircraft over the 250g threshold. Verify total flight weight before claiming Category 1 status.
Recommended sub-250g aircraft for Category 1 operations
Sub-250g Category 1-eligible aircraft
Consumer sub-250g aircraft in stock configuration — qualifies for Category 1 operations over people including open-air assemblies. Verify total flight weight (aircraft + payload) stays under 250g on your specific configuration.

Propeller guards / lightweight prop cages
Optional propeller guards for aircraft near the 250g threshold. Confirm added weight keeps the aircraft under Category 1's threshold. Some designs add safety margin without pushing the aircraft into a heavier category.

Bottom line
Category 1 covers most consumer sub-250g operations without special documentation. Category 2 requires manufacturer Means of Compliance declaration — few aircraft have it. Category 3 covers larger aircraft in restricted contexts. Category 4 is enterprise-only via type certification.
For most small operators, the practical decision is simple: if you need to operate over people, use a Category 1-eligible sub-250g aircraft, or plan the operation to buffer people from the flight path entirely. The middle categories exist but are more constrained than most operators realize.
Frequently Asked Questions
Can I fly my sub-250g drone over people without any special permissions?
Yes, in Category 1 — assuming the aircraft in its actual flight configuration is under 250g total and has no exposed rotating parts capable of laceration. Adding heavy accessories can push you over the threshold. Verify total flight weight before claiming Category 1 status.
What does 'no exposed rotating parts capable of laceration' mean in practice?
The FAA has interpreted this as a property tied to kinetic energy, not solely to whether props are covered. Most standard consumer sub-250g quadcopter props qualify — they don't produce laceration injuries at the kinetic energies typical of a Category 1 aircraft. Propeller guards add safety margin but aren't strictly required for most sub-250g quads.
Is my Mavic 3 eligible for Category 2 or 3 operations?
Only if DJI has filed a Means of Compliance declaration for that specific model. Most consumer and prosumer aircraft above 250g do not have accepted MoC declarations, which effectively excludes them from Category 2 and requires Category 3 restricted-context operations. Verify current manufacturer documentation before assuming eligibility.
Do I need to register a Category 1 aircraft?
For recreational operations, no — sub-250g aircraft flown recreationally don't require registration. For commercial operations under Part 107, yes — commercial registration is required regardless of aircraft weight.
Can I fly over a concert with a sub-250g drone?
Category 1 permits sustained flight over open-air assemblies of people, so a sub-250g aircraft operating in stock configuration is technically permitted. State privacy laws, event-specific rules, and controlled airspace around venues may still restrict the operation. Get the venue's permission and check for TFRs before flying.
What's the difference between Category 1 and having propeller guards?
Propeller guards are one way of ensuring no exposed rotating parts capable of laceration; a sub-250g aircraft with props too small to cause laceration is another. Category 1 eligibility is about the combination of weight + laceration risk, not specifically about physical prop guards.
