Luftfrie

Luftfrie is a term used in the context of aviation and air traffic management to describe a flight that is not subject to air traffic control (ATC) regulations. The term is derived from the German word "luftfrei," which translates to "air free." A luftfrie flight operates independently of ATC, meaning it is not required to follow specific flight paths, altitudes, or communicate with ATC for separation from other aircraft.

Luftfrie flights are typically used for low-level flights, such as those conducted by small aircraft, drones, or unmanned aerial vehicles (UAVs) operating within visual line of sight (VLOS). These flights are often conducted in areas where the risk of collision with other aircraft is low, such as over open water or in remote areas.

The concept of luftfrie flights is governed by national aviation regulations, which may vary from country to country. In some jurisdictions, luftfrie flights are subject to certain conditions, such as the requirement to operate within a specific altitude range or to maintain a safe distance from other aircraft. In other cases, luftfrie flights may be entirely prohibited or restricted.

The use of luftfrie flights has increased in recent years, particularly with the growth of the drone industry. However, the increased use of luftfrie flights has also raised concerns about safety and the potential for collisions with other aircraft. As a result, many aviation authorities are working to develop guidelines and regulations to ensure the safe and responsible use of luftfrie flights.
