AMC1 UAS.OPEN.030(2)(c) UAS operations in subcategory A2 ED Decision 2019/021/R ADDITIONAL THEORETICAL KNOWLEDGE OF SUBJECTS FOR THE EXAMINATION FOR SUBCATEGORY A2 (a) By passing the additional theoretical knowledge examination, the remote pilot should demonstrate that they: (1) understand the safety risks linked with a UAS operation in close proximity to uninvolved people or with a heavier UA; (2) are able to assess the ground risk related to the environment where the operation takes place, as well as to flying in close proximity to uninvolved people; (3) have a basic knowledge of how to plan a flight and define contingency procedures; and (4) understand how weather conditions may affect the performance of the UA. (b) The theoretical knowledge examination should cover aspects from the following subjects: (1) meteorology: (i) the effect of weather on the UA: (A) wind (e.g. urban effects, turbulence); (B) temperature; (C) visibility; and (D) the density of the air; (ii) obtaining weather forecasts; (2) UAS flight performance: (i) the typical operational envelope of a rotorcraft, for fixed wing and hybrid configurations; (ii) mass and balance, and centre of gravity (CG): (A) consider the overall balance when attaching gimbals, payloads; (B) understand that payloads can have different characteristics, thus making a difference to the stability of a flight; and (C) understand that each different type of UA has a different CG; (iii) secure the payload; (iv) batteries: (A) understand the power source to help prevent potential unsafe conditions; (B) familiarise with the existing different kinds of battery types; (C) understand the terminology used for batteries (e.g. memory effect, capacity, c‑rate); and (D) understand how a battery functions (e.g. charging, usage, danger, storage); and (3) technical and operational mitigations for ground risk: (i) low-speed mode functions; (ii) evaluating the distance from people; and (iii) the 1:1 rule.
