Operations within the Open Category

The Open Category offers a wide range of opportunities for drone operations, catering to different weight limits and specific requirements. This category allows drone pilots to conduct flights over uninvolved people, fly at a safe distance from urban areas, and operate drones with weights that fall within the prescribed limits. Let’s explore some examples of operations within the Open Category and the subcategories that define them.

Flights over Uninvolved People

One of the key advantages of the Open Category is the ability to fly drones over uninvolved people. Whether you’re capturing aerial photography at a crowded event or monitoring a public gathering, the Open Category enables you to conduct these operations without requiring additional certifications or permissions. It’s important, though, to ensure compliance with the weight limitations and other safety regulations.

Safe Distance from Urban Areas

In urban environments, it’s crucial to maintain a safe distance between drones and populated areas to ensure the safety of people on the ground. The Open Category allows for operations that prioritize this aspect by defining specific weight limits. Drones that fall within these weight limits can be flown at a safe distance from urban areas, enabling pilots to capture stunning footage and conduct surveys without endangering the public.

Weight Requirements and Subcategories

The Open Category is further divided into subcategories, each with its own weight requirements and regulations. These subcategories ensure clarity and conformity, enabling drone operators to understand the specific limitations and expectations associated with their operations. Let’s take a closer look at the three subcategories of the Open Category:

1. Subcategory A1: This subcategory encompasses drone operations with a maximum take-off weight of less than 900 grams. Drones falling into this category will typically have a C0 or C1 CE-marking. However, for drones weighing more than 250 grams, an online training and test may be required for safe and legal flight.
2. Subcategory A2: Subcategory A2 allows for drone operations with a maximum take-off weight of up to 4 kg. Drones in this category can have a C0, C1, or C2 CE-marking. Additional online and practical training and testing might be required for operating C2 drones within Subcategory A2.
3. Subcategory A3: For drone operations with a maximum take-off weight of up to 25 kg, Subcategory A3 provides the necessary framework. Drones falling into this category can have a C0 to C4 CE-marking or can even be privately built model aircraft. However, operations within Subcategory A3 must be conducted in areas where there is a reasonable expectation that no uninvolved person will be endangered.

It’s important to note that while the Open Category offers flexibility and opportunities, some areas may be designated as “Specific Category Only” by national aviation authorities. These areas might have specific restrictions or limitations on drone operations, which drone pilots must adhere to.

Now that we have explored the possibilities within the Open Category, it’s essential to understand the specific requirements associated with each subcategory. In the next section, we will dive deeper into the operations within Subcategory A1 and the corresponding requirements for safe and compliant operation.

Operations within Subcategory A1

Subcategory A1 of the Open Category allows for drone operations with a maximum take-off weight of less than 900 grams. Drones in this subcategory typically have a C0 or C1 CE-marking. However, for drones heavier than 250 grams in this subcategory, an online training and test are required before operating. Operations in Subcategory A1 may also have limitations on overflying uninvolved people.

Drones in Subcategory A1 are designed for low-risk operations and are suitable for hobbyist or recreational use. With a maximum weight limit of 900 grams, these lightweight drones are perfect for various outdoor activities such as aerial photography, videography, and surveying.

It’s important to note that drone operators in Subcategory A1 must follow specific requirements to ensure safe and responsible flying. These requirements include:

• Operating drones with a maximum take-off weight of less than 900 grams
• Ensuring the drone has a C0 or C1 CE-marking
• Completing an online training and test for drones heavier than 250 grams
• Adhering to limitations on overflying uninvolved people

This subcategory provides a balance between ease of use and safety, making it accessible for beginners and enthusiasts alike. The lightweight nature of Subcategory A1 drones allows for agile maneuverability and flexibility during flights, enabling users to capture stunning aerial shots and explore their surroundings from a unique perspective.

By complying with these requirements, drone operators can ensure the safe and responsible operation of their Subcategory A1 drones. This allows them to fully enjoy the benefits of aerial photography, explore new perspectives, and capture breathtaking moments from the sky.

Operations within Subcategory A2

Subcategory A2 of the Open Category allows for drone operations with a maximum take-off weight of up to 4 kg. This subcategory provides more flexibility for operators compared to Subcategory A1, allowing for the use of slightly heavier drones.

Drones in Subcategory A2 can have a C0, C1, or C2 CE-marking, indicating their conformity to specific regulations and safety standards. The CE-marking ensures that the drone meets the necessary requirements for operation within the Open Category. Different CE-markings may signify varying capabilities and features of the drone.

When operating a C4-marked drone in Subcategory A2, it may be necessary to maintain a safe horizontal distance of at least 30 meters from uninvolved people, unless the drone is in low-speed mode. This requirement ensures the safety of individuals in the vicinity of the drone during flight.

To ensure safe and competent operation of C2 drones in Subcategory A2, additional online and practical training and tests may be mandatory. These training and testing requirements serve to enhance the operator’s knowledge and skills in handling a slightly larger and potentially more complex drone.

Operating drones within Subcategory A2 provides an opportunity for more advanced and specialized operations within the Open Category. With the ability to fly drones weighing up to 4 kg and the option to utilize different CE-marked drones, operators have increased flexibility and versatility in conducting their drone operations.

Operations within Subcategory A3

Subcategory A3 of the Open Category allows for drone operations with a maximum take-off weight of up to 25 kg. It provides opportunities for operating larger drones, catering to specific industry needs and applications. Drones in this subcategory can have a C0 to C4 CE-marking, or they can be privately built, such as model aircraft. To ensure the safety of uninvolved persons, operations in Subcategory A3 must be conducted in areas where there is a reasonable expectation of no endangerment. This requires maintaining a safe horizontal distance of at least 150 meters from residential, commercial, industrial, or recreational areas.

Drones in Subcategory A3 are often utilized for professional enterprise applications, such as aerial photography, videography, surveying, and inspection. These operations may take place in remote areas, industrial sites, or construction zones where larger drones are needed to carry high-resolution cameras or specialized equipment. Compliance with the requirements for Subcategory A3 is essential to provide a responsible and efficient service while minimizing the risk to people and property.

Operators in Subcategory A3 must ensure that proper risk assessment and mitigation measures are in place before each flight. This includes carefully planning flight routes to avoid congested or populated areas and conducting periodic maintenance and inspections to ensure the airworthiness of their drones. Drones used in Subcategory A3 operations should also be equipped with appropriate safety features, such as collision avoidance systems and redundant flight control systems, to enhance the overall safety of the operation.

Here is an example of a table comparing the requirements for drone operations in Subcategories A1, A2, and A3 within the Open Category:

Understanding the specific requirements for operating in Subcategory A3 is crucial for drone operators looking to provide services within this weight class. Adhering to these requirements ensures compliance with aviation regulations, promotes safe operations, and enhances the overall reputation and professionalism of the drone industry.
