Fully knowledgeable about the Part 66 elements that are assigned to their scope of instruction, but also about the rules and specific procedures (MTOE etc..) governing the teaching in a controlled environment (Part 147 organisations). 2. Pedagogic and should know how to organize a lesson and how to efficiently deliver a course that clearly highlights the fundamental points; they should also be able to adapt his communication to a particular audience, what may require efforts to bypass, for instance, the language barrier or the very variable profiles of trainees in a same class (in terms of pre-existing knowledge/experience…). 3. Convincing and therefore should have the required experience proving that he has a good command of the subjects taught, at least sufficient to convince trainees that for instance may themselves have a pre- existing experience of the aircraft types to be taught. He should be in a position to understand, and possibly answer, a number of questions asked by trainees, and should be able to expose the links between the academic training delivered to the trainees and the actual maintenance tasks that these will have to accomplish all along his career. 4. The instructor should also keep and promote the “appropriate attitude” towards regulation and procedures, and in particular the strict adherence to approved maintenance practices and quality standards that can only be acquired through his own experience in a regulated (or governed) aviation environment. 5. Proficient and particular should be familiar with the tools or the training techniques used by the training organisation to support the lessons. They should also have a good command of the languages used in aviation literature such as A/C maintenance instructions and that will be used by trainees in an international Part 145 environment.
