Aviation engineering is the science of designing, developing, and assembling aircraft. Aviation engineers focus on airspace development, airport design, aircraft navigation technologies, and aerodrome planning. Professionals working in this field experiment with innovations in technology and materials, test planes, simulate flight conditions, and more.
Airworthiness is the ability of an aircraft or other airborne equipment or system to be operated in flight and on the ground without significant hazard to aircrew, ground crew, passengers or to third parties; it is a technical attribute of materiel throughout its lifecycle. A Certificate of Airworthiness is a permit for operation, issued for an aircraft by the national aviation authority in the state/nation in which the aircraft is registered. For aircraft used in commercial passenger or cargo operations, a Standard Airworthiness Certificate is mandatory. This Certificate of Airworthiness is maintained by performing the required maintenance actions.
Airworthiness Directives are issued by EASA, acting in accordance with the Basic Regulation on behalf of the European Community, its Member States and of the European third countries that participate in the activities of EASA under Article 66 of that Regulation.
Continious Airworthiness Management
Continuing Airworthiness management is the process by which an aircraft is kept in a condition where it remains airworthy throughout its life - or in other words i.e. technically fit for flight.
In the words of International Civil Aviation Organisation (ICAO): “All of the processes ensuring that, at any time in its life, an aeroplane complies with the technical conditions fixed to the issue of the Certificate of Airworthiness and is in a condition for safe operation"
