UAM Terms

The definition of the most common UAM terms

Advanced Air Mobility (AAM)

 Advanced Air Mobility (AAM) expands the Urban Air Mobility (UAM) concept to rural areas and also incorporates intraregional UAM services.

Aeronautical Information Management (AIM)

 A portal that allows pilots, airline operators and other Aeronautical Information Services (AIS) users to access the latest flight information as well as submit e-flight plans.

Air Taxi

Manned Vertical Take-Off and Landing Aircraft carrying humans along short routes, which are not serviced by conventional civil aviation operators.

Air Traffic Control (ATC)

A service provided by personnel trained and certified by relevant aviation authorities responsible for monitoring and controlling all air traffic within a specific area, such as EASA, FAA and others.

Air Traffic Management (ATM)

The necessary toolkit of airborne and ground-based functions (air traffic services, airspace management and air traffic flow management) required to ensure the safe, secure and efficient movement of aircrafts during all phases of operation.

Autonomous Aerial Vehicle (AAV)

Aircraft designed to operate autonomously, predominantly without a human involved in the mission control. It is close, by definition, to the Unmanned Aerial Vehicles (UAVs), and not all UAVs are AAVs, since some UAVs require a remote operator or pilot.

Beyond Visual Line of Sight (BVLOS)

Sometimes also called BLOS. This is where the flying of a drone is without a pilot maintaining visual line of sight on the aircraft at all times.

Concept of Operations (in Urban Air Mobility) [ConOps (UAM)]

A definition of operations, operational environments and applicable legislative and/or regulative framework documents, in the context of Urban Air Mobility operations.


Aircraft (Unmanned Aerial Vehicle (UAV)) or vehicle (e.g. underwater drones) designed to operate autonomously (pre-programmed, without a human in control) or remotely (pilot controls the drone on the ground). Also called Unmanned Aerial Vehicle (UAV) or Unmanned Aircraft (UA) when referring to drone aircrafts.

European Union Aviation Safety Agency (EASA)

Agency of the European Union responsible for designing the civil aviation safety framework.

Electric Vertical Take-Off and Landing (eVTOL)

Type of aircraft that uses electrical propulsion to takeoff, hover, and land vertically.


Technology that uses global positioning system (GPS & GLONASS) to establish a virtual geographic boundary to prevent drones from flying into specific area.

Geographic Information System (GIS) Tool

Computer-based tools that allow the user to store and edit spatial and non-spatial data, analyze spatial information output, and visually share the results of these operations by presenting them as maps.


Landing site or airport designed to support take-off and landing operations, including taxiing and parking for (electric) Take-Off and Landing ((e)VTOL) aircrafts, Autonomous Aerial Vehicles (AAV), helicopters and other small aircrafts.

Inertial Measurement Unit (IMU)

An electronic device that uses accelerometers, gyroscopes, and sometimes magnetometers to measure and report specific force, angular rate, and magnetic field of the drone in flight.

Metropolitan area

Populated region with a high-density core (city) and lower density peripheral region (suburbs, rural areas).

Public-Private Partnership (PPP) 

Cooperative arrangement and/or undertaking between two and/or more public and private stakeholder organisations, aiming long term collaboration for the sake of both public and private interests.

Regional Air Mobility (RAM)

Using existing small airports to transport people in small aircraft over distances of up to 300 kilometers.

Remotely Piloted Aircraft (RPA)

Refers to a high-level Unmanned Aerial Vehicle (UAV) operated from a remote pilot station. Its pilot is required to have a significant amount of training compared to pilots of UAV models mostly used for recreational flights, who require minimal or no training at all for their operation.

Remotely Piloted Aircraft System (RPAS)

Consists of the Remotely Piloted Aircraft (RPA) and all the necessary components for its operation, including its hardware, software, control links and the associated remote pilot station(s).

Joint European ATM Research Joint Undertaking (SESAR JU)

A platform for all initiatives and projects of the EU towards the integration of integrating innovative ATM and UTM solutions, as well as U-Space, towards a large-scale and international PPP in the relevant multidisciplinary thematic field.
