AMC 147.A.130(a) Training procedures and quality system

This guidance material provides some clarifications for the incorporation of new training methods and training technologies in the procedures for aircraft maintenance training. The classic training method is a teacher lecturing the pupils in a classroom. Commonly the training tools are a blackboard and training manuals. New technologies make it possible to develop new training methods and use other training tools, e.g. multimedia-based training and virtual reality. A combination of several training methods/tools is recommended in order to increase the overall effectiveness of the training. Simulation cannot be eligible as a sole training or assessment tool for basic hand skills such as wiring, welding, drilling, filing, wire locking, riveting, bonding or any other skill where competence may only be achievable by performing a hands-on activity. Three tables are provided to illustrate the possibilities for the use of different training methods and tools: Table 1: Training tools Table 2: Training methods Table 3: Combination of training methods and tools and their use Table 1 lists existing training tools that may be selected for basic training.

Table 1: Training tools Training tools Description 1 Slideshow presentation A structured presentation of slides. 2 Manuals Comprehensive and controlled publication of a particular topic. 3 Computer (desktop PC, laptop, An electronic processing device that can hold and display etc.) information in various media. 4 Mobile devices (such as, but not A mobile electronic processing device that can hold and display limited to, tablets, smart information in various media. phones, etc.) 5 Videos Electronic media for broadcasting moving visual images. 6 MSTD — Maintenance A training device that is intended to be used in maintenance simulation training device training, examination, and/or assessment for a component, system or entire aircraft. The MSTD may consist of hardware and software elements.

Annex IV to ED Decision 2020/002/R

Training tools Description

7 Mock-up A scaled or full-size replica of a component, system or entire aircraft that preserves (i.e. is an exact replica of) the geometrical, operational or functional characteristics of the real component, system or entire aircraft for which maintenance training is delivered with the use of such a replica. 8 Virtual reality A computer-generated three-dimensional (3D) environment which can be explored and possibly interacted with. 9 MTD — Maintenance training Maintenance training device is any training device other than device an MSTD used for maintenance training and/or examination and/or assessment. It may include mock-ups. 10 Real aircraft A suitable aircraft whose condition allows teaching a selection of maintenance tasks that are representative of the particular aircraft or of the aircraft category. ‘Suitable’ means an aircraft of the type or licence (sub)category (if the licence (sub)category aircraft is outfitted with the same equipment subject to the particular lesson module(s) and is sufficiently similar so that the lesson objective(s) can be satisfactorily accomplished) for type training, or an aircraft representative of the licence (sub)category for basic training, and excludes ‘virtual aircraft’. ‘Condition’ means that the aircraft is equipped with its main components and that the systems can be activated/operated when this is required by the learning objectives. 11 Aircraft component A suitable aircraft component used to teach specific maintenance tasks off-the-wing. This may include but is not limited to tasks such as borescope inspections, minor repairs, testing, or the assembly/disassembly of sub-components. ‘Suitable’ means that the condition of the component should fit the learning objectives of the tasks and, when appropriate, may feature existing defects or damages. 12 Augmented reality An enhancement (modification, enrichment, alteration or manipulation) of one’s current perception of reality elements of a physical, real-world environment following user’s inputs picked up by sensors transferred to rapid streaming computer images. By contrast, virtual reality replaces the real world with a simulated one. 13 Embedded training A maintenance training function that is originally integrated into the aircraft component’s design (i.e. a centralised fault display system).

Annex IV to ED Decision 2020/002/R

Training tools Description

14 Classroom A physical, appropriate location where learning takes place.

15 Virtual classroom A simulated, not physical, location where synchronous learning takes place. 16 Virtual aircraft A simulated, not physical, aircraft that may be used in theoretical training, practical training, examination or assessment. Note: Synthetic training devices (STDs) is a generic term used for systems using hardware and/or software, simulating the behaviour of one or more aircraft systems or a complete aircraft, such as maintenance simulation training devices (MSTDs), maintenance training devices (MTDs) and flight simulation training devices (FSTDs).

Table 2 lists existing training methods that may be selected for basic training. Table 2: Training methods Training Instructor Student- Blended Description (1) (2) (3) method -centred centred training Assisted Assisted learning or mentorship represents an X X X learning ongoing, close relationship of dialogue and (mentoring) learning between an experienced /knowledgeable instructor and a less experienced/knowledgeable student in order to develop experience/knowledge of students. Computer- CBT is any interactive means of structured X X X based training training using a computer to deliver a content. (CBT) (Note: Not to be confused with competencybased training that also uses the acronym ‘CBT’) Demonstration A method of teaching by example rather than X X explanation. Distance Distance learning reflects training situations in X X learning which instructors and students are physically asynchronous separated. It is asynchronous if the teacher and the students do not interact at the same time. Distance Distance learning reflects training situations in X X learning which instructors and students are physically synchronous separated. It is synchronous if the teacher and the students interact at the same time (real time).

Annex IV to ED Decision 2020/002/R

Training Instructor Student- Blended Description (1) (2) (3) method -centred centred training e-learning Training via a network or electronic means, X X X with or without the support of instructors (etutors). Lecturing Practice of face-to-face delivery of training X X (instructor- and learning material between an instructor led/face to and students, either individuals or groups. face) Mobile learning Any sort of learning that happens when the X X X (M-learning) student is not at a fixed, predetermined location, using mobile technologies. Multimedia- Any combined use of different training media. X X X based training Simulation Any type of training that uses a simulator X X X imitating a real-world process or system. Web-based Generic term for training or instruction X X X training (WBT) delivered over the internet or an intranet using a web browser. Note: The purpose of this table is to provide a short definition for each associated training method and to relate each method to the focus of the learning. It is not meant to comprehensively explore and identify the capabilities of each training method herein included. (1) ‘Instructor-centred’ means that the instructor is responsible for teaching the student. (2) ‘Student-centred’ means that the student is responsible for the learning progress. (3) ‘Blended training’ includes different instructional methods and tools, different delivery methods, different scheduling (synchronous/asynchronous) or different levels of guidance. Blended training allows the integration of a range of learning opportunities. (4) ‘Multimedia-based training’ by definition uses various media to achieve its objective, thus, none of the single media listed is per se a complete solution for training.

Table 3 presents the combination of training methods and tools that may be taken into account for theoretical and practical training. The table is intended to support potential delivery methods. Additional training methods and further use of those methods could be acceptable to the competent authority when demonstrated as supporting learning objectives.

This table relates a given training method to a list of acceptable training tools (code), oriented to deliver the

theoretical elements, practical elements or on-the-job training associated with their specific learning objectives.

(1) Limited suitability. It means that the respective training method may be used but with limited results, thus

requiring the support of a complementary training method to fulfil the learning objectives.
