UAVs, UV or Drone?

Definitions and acronyms are part of everyday life. We are full of definitions and acronyms, which are always used with the utmost ease, assuming that everyone knows them. But this is not true!

In Italy, for example, in the field of drones we have become familiar with acronyms such as APR, SAPR and definitions that derive directly from the ENAC regulation, but these are not valid internationally.

In fact, when the European drone regulation comes into force, initially planned for 1st July 2020 – but probably postponed due to the covid-19 emergency -, there will be new definitions and new acronyms that it is good to know. Let’s see them together, in rigorous alphabetical order.

Definitions and acronyms

A

AMC – Acceptable Means of Compliance – the standards published by EASA for compliance through European regulations.

C

Certified category – Certified category is one of the categories defined in the EASA implementing regulation EU 2019/947. It therefore defines a category of drones that must meet specific requirements.

D

DOA – Design Organization Approval – certification relating to aeronautical design companies.

E

EASA – European Aviation Saftey Agency – issues guidelines-Opinion approved by the European Parliament.

EVLOS – Extended Visual Line of Sight, possibility of flying beyond the visual line (Visual Line of Sight), with the help of methods that meet the visual flight conditions, for example with the help of observer. The role of the observer is to assist the pilot when the drone disappears from the line of sight or is far away.

G

GC – Ground Control – indicates the drone control system or the remote control. In some cases it is used to indicate the complex of the radio control, laptop, antenna etc.

H

Hovering – Volo stazionario – i.e. the flight of the aircraft in the same position (typical of helicopters and drones).

I

ICAO – International Civil Aviation organization – United Nations agency that defines the rules and techniques of air navigation internationally.

ISA – International Standard Atmosphere – the set of standards used for the calibration of instruments at sea level.

M

MTOM – Maximum Take Off Mass, i.e. the maximum take-off mass of the drone, including the payload (camera or sensor), batteries or fuel. It is the equivalent of the Italian term MOD – Operational Take-off Mass.

O

Open category – Open category is one of the categories defined in the EASA Implementing Regulation EU 2019/947. It therefore defines a category of drones that must meet specific requirements.

For more information on the “Open” category, see the “European EASA Drones – Catg. Open” article from the Blog.

R

RPA – Remotly Piloted Aircraft – indicates the car (or drone) in the strict sense. It is the equivalent of the term APR (Remote Piloted Aircraft).

RPAS – Remotly Piloted Aircraft Systems – indicates the whole system – machine (or drone) and its piloting device -. It is the equivalent of the term SAPR (Remote Piloted Aircraft System).

RPS – Remote Pilot Station – indicates the remote control, with which to control the flight of the drone.

S

Specific category – Specific category is one of the categories defined in the EASA Implementing Regulation EU 2019/947. It therefore defines a category of drones that must meet specific requirements.

For more information on the “Specific” category, see the “EASA European Drones Regulation – Catg. Specific” Article from the Blog.

T

TCO – Third Country Operator – Third-country air operators.

U

UA – Unmanned Aircraft – remotely piloted unmanned aircraft. It is the equivalent of the term APR (Remote Piloted Aircraft).

UAS – Unmanned Aicraft Sytsem – is the set of the UA and its piloting device. It is the equivalent of the term SAPR (Remote Piloted Aircraft System).

UAV – Unmanned Aerial Vehicle – term used to indicate the machine system and driving device. It is the equivalent of the term SAPR (Remote Piloted Aircraft System).
