Sofema Online (SOL) www.sofemaonline.com looks at the process & methodology related to Distance Learning in support of EASA Part 147 objectives.


Distance learning training method is introduced by Annex IV of ED decision 2020/002 in AMC 147.A.130(a), which is applicable to both basic and type training organisation.

AMC 147.A.130(a) defines 2 different types of distance learning training methods:

» Distance learning asynchronous:

o Distance learning reflects training situations in which instructors and students are physically separated. The instructor and the students do not interact at the same time.

Note - This training method is ‘’Student-centred’’ (i.e. the student is responsible for the learning progress). (Not acceptable for delivery of EASA Part 147 Theoretical Training).

» Distance learning synchronous:

o Distance learning reflects training situations in which instructors and students are physically separated. The teacher and the students interact at the same time (real-time).

Note - This training method is ‘’Instructor centered’’ (i.e. instructor is responsible for teaching the student).

It is possible to deliver a blended training which integrates a range of learning opportunities by implementing:

» different training tools (e.g. slideshows, virtual aircraft, virtual classroom..);
» different delivery methods (CBT, WBT, synchronous DSL, lecturing…);
» different scheduling (synchronous/asynchronous);
» different levels of guidance.

Synchronous DSL can be used to teach theoretical part, and certain practical elements.

Training Tools

As per AMC 147.A.130(a) table 3, the following training tools can be used during synchronous DSL either for the theoretical part (basic or type) or practical element of the type training:

» Slideshow presentation
» Manuals
» Computer (desktop, PC, laptop, etc...)
» Mobile devices (such as, but not limited to, tablets, etc.)
» Videos
» Virtual reality
» Virtual classroom
» Virtual aircraft

A combination of several training methods/tools is recommended in order to increase the overall effectiveness of the training.

Mobile phones cannot be used for the video presentation of the virtual classroom as the screen size does not allow to attend the virtual classroom with sufficient comfort (i.e. audio-only is acceptable on mobile).

Approval process of the addition of DSL training method

In order to be approved to use the DSL training method on a permanent basis, the training organisation has:

» To submit an EASA Form 12 to apply for off-site training, only when not previously approved;
» To submit for approval the amended MTOE describing the implementation procedure of DSL training method and associated training tools;
» To be audited by the surveyor either on-site or remotely (remote audit not applicable for initial application);
» Similar approval process is required whether it is an initial application or a change of an existing approval.

Maintenance Training Organisation Exposition Amendment to Support DSL Training

At the minimum the following MTOE chapter have to be amended to describe the use of DSL:

» 2.1 Organisation of courses
» 2.2 Preparation of course material
» 2.3 Preparation of classroom and equipment
» 2.5 Conduct of theoretical training and practical training
» 2.6 Records of training carried out
» 2.8 Training at locations not listed in paragraph 1.6
» 3.6 Qualifying the instructors
» 3.8 Record of qualified instructors and examiner

Alternatively, DSL procedure can be consolidated into a procedure describing only applicable condition requirements. (In which case Applicable MTOE chapters should make a clear reference to this additional procedure.
