# 147.A.115 Instructional equipment

Annex IV (Part-147) · Regulation (EU) No 1321/2014 · EAR revision 2 Sep 2025

IR Implementing rule

## 147.A.115 Instructional equipment

(a) Each classroom shall have appropriate presentation equipment of a standard that ensures that students can easily read presentation text, drawings, diagrams and figures from any position in the classroom.

For virtual training environments, the training content shall be designed in such a way to assist students in their understanding of the particular subject matter, ensuring that students can easily read presentation text, drawings, diagrams and figures.

The presentation equipment may include representative [maintenance](https://avioverse.aero/glossary/easa/maintenance) simulation training devices (MSTDs) to assist students in their understanding of the particular subject matter where such devices are considered beneficial for such purposes.

(b) The basic training workshops and/or maintenance facilities as specified in point 147.A.100(d) must have all tools and equipment necessary to perform the approved scope of training.

(c) The basic training workshops and/or maintenance facilities as specified in point 147.A.100(d) must have an appropriate selection of [aircraft](https://avioverse.aero/glossary/easa/aircraft), engines, aircraft parts and avionic equipment.

(d) The aircraft type training [organisation](https://avioverse.aero/glossary/easa/organisation) as specified in point 147.A.100(e) must have access to the appropriate aircraft type. MSTDs may be used when such training devices ensure adequate training standards.

AMC Acceptable means of compliance

## AMC1 147.A.115(a) Instructional equipment

If the [maintenance](https://avioverse.aero/glossary/easa/maintenance) training [organisation](https://avioverse.aero/glossary/easa/organisation) transfers knowledge through a virtually controlled environment (e.g. distance learning, computer-based training (CBT) or multimedia-based training (MBT)), the organisation should ensure that:

the computer system requirements are made known to the end user;

the students’ activities are traceable, documented and recorded; and the computer system requirements of any third-party provider are covered by a written agreement concluded between the two parties and includes the terms of delivery, data security and data integrity.

GM Guidance material

## GM1 147.A.115(a);(d) Instructional equipment

1\. Refer to the GM to Section 3 of Appendix III to Part-66 for the description, and to point 7 of the AMC to Section 1 of Appendix III to Part-66 for the definitions.

2\. It is acknowledged that situations could exist where the size and complexity of such MSTDs and/or MTDs may require dedicated infrastructure. Such instances should be acceptable provided that student access to, and the use of, the respective MSTDs/MTDs is appropriately ensured.

AMC Acceptable means of compliance

## AMC 147.A.115(c) Instructional equipment

1\. An appropriate selection of [aircraft](https://avioverse.aero/glossary/easa/aircraft) parts means appropriate in relation to the particular subject module or sub-module of Part-66 being instructed. For example the turbine engine module should require the provision of sufficient parts from different types of turbine engine to show what such parts look like, what the critical areas are from a [maintenance](https://avioverse.aero/glossary/easa/maintenance) viewpoint and to enable disassembly/assembly exercises to be completed.

2\. Appropriate aircraft, engines, aircraft parts and avionic equipment means appropriate in relation to the particular subject module or sub-module of Part-66 being instructed. For example category B2 avionic training should require amongst other equipment, access to at least one type of installed autopilot and flight director system such that maintenance and system functioning can be observed and therefore more fully understood by the student in the working environment.

3\. ‘Access’ may be interpreted to mean, in conjunction with the facilities requirement of 147.A.100(d), that there may be an agreement with a maintenance [organisation](https://avioverse.aero/glossary/easa/organisation) approved under Part-145 to access such parts, etc.
