ED Decision 2022/002/R

THEORETICAL KNOWLEDGE SUBJECTS FOR BASIC ONLINE THEORETICAL KNOWLEGDE TRAINING COURSES AND THEORETICAL KNOWLEGDE EXAMINATIONS FOR SUBCATEGORIES A1 AND A3

The acquisition of theoretical knowledge by the remote pilot should cover at least the following theoretical knowledge subjects:

(a)     Air safety:

(1)     non-reckless behaviour, safety precautions for UAS operations and basic requirements regarding dangerous goods;

(2)     starting or stopping the operations taking into account environmental factors, UAS conditions and limitations, remote pilot limitations and human factors;

(3)     operation in visual line of sight (VLOS) and in very low level (VLL), which entails:

(i)      keeping a safe distance from people, animals, property, vehicles, and other airspace users;

(ii)     the identification of assemblies of people;

(iii)     a code of conduct in case the UA encounters other traffic;

(iv)     respecting the height limitation; and

(v)      when using a UA observer, the responsibilities and communication between the UA observer and the remote pilot; and

(4)     familiarisation with the operating environment, in particular:

(i)      how to perform the evaluations of the presence of uninvolved person in the overflown area as required in UAS.OPEN.020(1) and UAS.OPEN.040(1); and

(ii)     informing the people involved;

(b)     Airspace restrictions:

(1)     obtain and observe updated information about any flight restrictions or conditions published by the MS according to Article 15 of the UAS Regulation[94];

(2)     describe the types of geographical zones and the procedures for receiving a flight authorisation; and

(3)     upload the geographical zones onto the geo-awareness system;

(c)      Aviation regulations:

(1)     Introduction to EASA and the aviation system;

(2)     Regulation (EU) 2019/945 and Regulation (EU) 2019/947:

(ii)     subcategories in the ‘open’ category and the associated classes of UAS;

(iii)     registration of UAS operators;

(iv)     the responsibilities of the UAS operator;

(v)      the responsibilities of the remote pilot; and

(vi)     incident – accident reporting;

(d)     Human performance limitations:

(2)     human perception:

(i)      factors influencing VLOS;

(ii)     the distance of obstacles and the distance between the UA and obstacles;

(iii)     evaluation of the speed of the UA;

(iv)     evaluation of the height of the UA;

(v)      situational awareness; and

(vi)     night operations.

(e)     Operational procedures:

(1)     pre-flight:

(i)      assessment of the area of operation and the surrounding area, including the terrain and potential obstacles and obstructions for keeping VLOS of the UA, potential overflight above uninvolved persons, and the potential overflight above critical infrastructure;

(ii)     identification of a safe area where the remote pilot can perform a practice flight;

(iii)     environmental and weather conditions (e.g. factors that can affect the performance of the UAS such as electromagnetic interference, wind, temperature, etc.); methods of obtaining weather forecasts; and

(iv)     checking the condition of the UAS;

(2)     in-flight:

(i)      normal procedures;

(ii)     determine the UA’s attitude, altitude, and direction of flight;

(iii)     observe the airspace for other air traffic or hazards;

(iv)     determine that the UA does not pose a danger for the life or property of other people; and

(v)      contingency and emergency procedures for abnormal situations:

(a)     managing the UAS flight path in abnormal situations;

(b)     managing the situation when the UAS positioning equipment is impaired;

(c)      managing the situation of incursion of a person into the area of operation, and taking appropriate measures to maintain safety;

(d)     managing the exit from the area of operation as defined during the flight preparation;

(e)     managing the situation when a manned aircraft flies near the area of operation;

(f)      managing the incursion of another UAS into the area of operation;

(g)     dealing with a situation of a loss of attitude or position control caused by external phenomena; and

(h)     following the C2 loss-of-link procedure;

(3)     post-flight:

(i)      maintenance; and

(ii)     logging of flight details;

(f)      UAS general knowledge:

(ii)     data link frequencies and spectrums; and

(iii)     automatic flight modes, override and manual intervention;

(4)     familiarisation with the instructions provided by the user’s manual of a UAS, and in particular with regard to:

(i)      overview of the main elements of the UAS;

(ii)     limitations (e.g. mass, speed, environmental, duration of battery, etc.);

(iii)     controlling the UAS in all phases of flights (e.g. the take-off, hovering in mid-air, when applicable, flying basic patterns and landing);

(iv)     features that affect the safety of flight;

(v)      setting the parameters of the lost link procedures;
