UTM (UAS Traffic Management System) - traffic management system for unmanned aircraft systems

The UAS Traffic Management System (UTM) is a drone traffic management system that provides a combined air situation picture of manned and unmanned aircraft, as well as other functions for safe and efficient drone beyond visual line of sight (BVLOS) operations in compliance with regulations. For all phases of flight (pre-flight, in-flight and post-flight phase), the UTM provides authoritative services for the safe operation of UAS in the airspace. In the pre-flight phase, the controller can register in the UTM, plan his mission and cross-check it (Are no-fly zones / airspace restrictions present? Are there other registered flight movements? Do I need an ascent permit or a SORA?). In the in-flight phase, the remote pilot can track his drone in real time and observe other aircraft in a combined aerial situation display, including those outside the user's line of sight (manned as well as unmanned registered in the UTM). He also receives real-time data such as photos or videos as needed. The UTM components of the post-flight phase help with the evaluation and follow-up of the flight (e.g., maintenance of the logbook, incident management, battery management).

U-Space Service Provider (USSP)

The U-Space Service Provider coordinates unmanned air traffic in U-Space and is responsible for its safety. To this end, it must provide four different technical services:- Provision of a complete air situation picture for the drone pilots (Traffic Information Service)- Continuous monitoring of drone flight movements in the respective U-Space area (Network Identification Service)- Continuous transmission of relevant airspace information to the drone pilots (Geo-awareness Service)- Provision of services for flight registration and flight authorization for drone pilots (Flight Authorization Service).

U-Space

A U-Space is an airspace element for the use of unmanned aerial vehicles. The U-Space airspace is clearly demarcated from the rest of the airspace, both in terms of its maximum altitude and its geographical extent. In the U-Space, there are clear organizational structures and processes that manage the individual drone flights (e.g., the registration and deregistration of individual flights, the planning of flight routes, etc.) and at the same time ensure that these take place safely. In addition, these ensure safe and smooth interaction with manned air traffic.

Uncontrolled airspace

Airspace outside the area of responsibility of air traffic control.

Uninvolved persons

Persons who are not involved in UAS operation or who are not familiar with the UAS operator's instructions and safety procedures.

Unmanned glider

UAS operators

Unmanned Aircraft System Operator. A legal or natural person that operates or intends to operate one or more UAS.

UAS Flight Authorization Service

The goal of this service is to provide USSPs with situational awareness of all UAS traffic to be operated in U-Space, even in uncontrolled airspace. This allows USSPs to apply prioritization rules before authorization is granted. With the information about the intended flight and other information about the type of operation and its duration, as well as some associated aircraft performance, USSPs should be able to manage traffic flow and mitigate potentially conflicting flights before those flights occur. To do this, all USSPs are required to share flight authorization applications with each other when more than one USSP provides U-Space services in U-Space airspace (while, of course, complying with the GDPR requirements).

UAS (unmanned aircraft system) - Unmanned aircraft system

An unmanned aerial vehicle and the equipment for its remote control. Synonyms: UAV, unmanned aerial system, unmanned aerial vehicle, model aircraft.

UA (unmanned aircraft) - Unmanned aircraft

VTOL (Vertical Take-Off and Landing)

Vertical takeoff and landing

VLOS (Visual Line Of Sight operation) - operation in direct sight

A UAS mode of operation in which the remote pilot is able to maintain uninterrupted and unassisted visual contact with the unmanned aircraft so that he can control its flight path to avoid collisions with other aircraft, people, and obstacles.

VFR (Visual Flight Rules)

VFR flights are "see and be seen" flights where the pilot orients himself to external reference points (lakes, railroad lines, highways, etc.). VFR flights are not under the control of air traffic control or a controller; pilots are responsible for avoiding collisions with other airspace users.

Wind

Vertical and horizontal air movements can have a significant influence on the operation of a UAS. Remote pilots must take this influence into account in their flight planning. On the one hand, the different air movements directly affect the flight path of the unmanned aerial vehicle. On the other hand, steering against the air movement always means higher battery consumption and consequently a sometimes considerable reduction in flight time.

X configuration

Most manufacturers (DJI, Yuneec, Parrot) design multicopters as X-configurations. The motors are offset by 45° to the direction of flight so that the propellers and arms are not visible in the direction of flight when taking photos or filming.
