The EU Open category — A1, A2, and A3 explained

Most drone pilots in Latvia fly in the Open category. Inside it, the rules split into A1, A2, and A3. The differences matter because they decide three things at once:

  • which aircraft you can use
  • how close you may fly to uninvolved people
  • which qualification you need

The short comparison

SubcategoryMain ideaAircraft most commonly usedPilot qualification
A1lighter aircraft, closest to people<250 g, C0, C1A1/A3 where required
A2closer operations with a C2 aircraftC2A1/A3 + A2
A3flights far from people and built-up areasC0 to C4, depending on the caseA1/A3

A1

A1 has the fewest limits around uninvolved people, but it still does not let you fly over crowds.

In practice:

  • aircraft under 250 g and C0 aircraft may be used in A1
  • C1 aircraft may also be used in A1
  • with C1, the remote pilot must not fly over uninvolved people on purpose

So A1 is not "fly anywhere". It is simply the Open-category subcategory with the lightest aircraft and the smallest gap from people.

A2

A2 is the middle ground. It exists for flights with a C2 aircraft closer to uninvolved people than A3 would allow.

The core distance rule is:

  • at least 30 m horizontally from uninvolved people
  • you may go closer in low-speed mode, but the distance still stays tight

For Latvia, the public CAA materials describe A2 as a separate path:

  1. valid A1/A3 proof first
  2. practical self-training
  3. a separate A2 exam

A3

A3 is the subcategory for flights far from uninvolved people and away from residential, commercial, industrial, and recreational areas.

The CAA Open-category summary makes two points:

  • the flight must stay at least 150 m horizontally from those areas
  • inside the operating area, you still keep your distance from uninvolved people

A3 is often the fallback for heavier or older aircraft when A1 or A2 does not fit.

Which certificate goes with which subcategory

The qualification structure is simpler than many summaries make it sound:

  • one A1/A3 certificate covers both A1 and A3
  • A2 needs the extra A2 step

There is no separate "A1-only" or "A3-only" certificate.

What about drones under 250 g?

This is the point most often oversimplified online.

For aircraft under 250 g:

  • operator registration may still be required, especially when the aircraft has a camera and is not a toy
  • but operator registration and A1/A3 qualification are not the same thing

So the right question is not just "Does it have a camera?". The right questions are:

  • what is the aircraft class or mass?
  • which subcategory applies?
  • does the CAA require pilot qualification in that case?

Older aircraft

The transition period is over. The Latvian CAA summary explains that older drones without a C-class label can still be used, but they have fewer options than class-marked aircraft.

For an older aircraft, it is worth checking:

  • the aircraft mass
  • whether the flight fits A1 or only A3
  • whether a newer class-marked aircraft would make the job easier

A good way to read Open

If you want to stay out of trouble, do not start with product names or marketing labels. Start with:

  1. subcategory
  2. aircraft class or mass
  3. distance to uninvolved people
  4. geographical-zone restrictions

Once those four are clear, most Open-category decisions get much easier.

Frequently asked questions

+What is the difference between A1, A2, and A3?

They are the three Open-category subcategories. A1 is for lighter drones flown closer to people (but never over assemblies of people), A2 is for a C2 drone flown closer to people than A3 allows, and A3 is for flights far from people and at least 150 m from residential, commercial, industrial or recreational areas.

+Which certificate covers which subcategory?

One A1/A3 certificate covers both A1 and A3. A2 needs a separate extra step on top. There is no separate A1-only or A3-only certificate.

+Can I fly a drone under 250 g without any certificate?

A sub-250 g drone may still need operator registration, especially with a camera and if it is not a toy, but registration and A1/A3 qualification are not the same thing. Whether you need pilot qualification depends on the aircraft class or mass and the subcategory.

+Can I still use an older drone without a C-class mark?

Yes. Older drones without a class mark can still be flown, but with fewer options than class-marked aircraft — typically A1 under 250 g, or A3.

+How should I decide which Open-category rules apply?

Start with four things in order — the subcategory, the aircraft class or mass, the distance to uninvolved people, and any geographical-zone restrictions. Once those are clear, most Open-category decisions are straightforward.
