2.For the purpose of this Regulation, the following definitions shall apply:
(a)“JAA” means the “Joint Aviation Authorities”;
(b)“JAR” means “Joint Aviation Requirements”;
(c)“Part 21” means the requirements and procedures for the certification of aircraft and related products, parts, appliances, control and monitoring units and control and monitoring unit components, and of design and production organisations laid down in Annex I to this Regulation;
(d)“Part 21 Light” means the requirements and procedures for the certification or declaration of design compliance of aircraft other than unmanned aircraft intended primarily for sports and recreational use and of related products and parts, and declaration of design and production capability of organisations laid down in Annex Ib (Part 21 Light) to this Regulation;

(ii)a sailplane or powered sailplane of 1 200 kg MTOM or less;
(iii)a balloon with a maximum design lifting gas or hot air volume of not more than 3 400 m3 for hot air balloons, 1 050 m3 for gas balloons, 300 m3 for tethered gas balloons;
(iv)an airship designed for not more than four occupants and a maximum design lifting gas or hot air volume of not more than 3 400 m3 for hot air airships and 1 000 m3 for gas airships;
(j)“ELA2 aircraft” means the following manned European Light Aircraft:
(i)an aeroplane with a maximum take-off mass (MTOM) of 2 000 kg or less that is not classified as complex motor-powered aircraft;
(ii)a sailplane or powered sailplane of 2 000 kg MTOM or less;
(iii)a balloon;
(iv)a hot air airship;
(v)a gas airship complying with all of the following characteristics: 3 % maximum static heaviness, non-vectored thrust (except reverse thrust), conventional and simple design of structure, control system and ballonet system, non-power assisted controls;
(vi)a rotorcraft with an MTOM not exceeding 600 kg which is of a simple design, designed to carry not more than two occupants, not powered by turbine and/or rocket engines; restricted to VFR day operations;
(k)“operational suitability data (OSD)” means data, which is part of an aircraft type certificate, restricted type certificate or supplemental type certificate, consisting of all of the following:
