MEL & MMEL awareness training

The Master Minimum Equipment List (MMEL) and 
Minimum Equipment List (MEL) training aims to:

. specify, for a given aircraft, the minimum equipment required and the conditions to be met for its certificate of airworthiness to remain valid
. define the operational procedures needed to maintain the required level of safety, taking the inoperative equipment into account
. define the maintenance procedures needed to maintain the required level of safety, and the procedures needed to make any inoperative equipment safe.
This training is taken by flight crews and technicians from many types of operators: airlines, maintenance organizations, flight schools...

Course objectives

The MMEL is an approved document created specifically to regulate the operation of an aircraft type with inoperative equipment. For a specific aircraft type, it sets out which equipment may be inoperative under certain conditions, and it is the basis of the MEL.
This module provides a quick foundation of understanding, ideal before developing or revising a MEL. It is a basic awareness course.
On completion of this training, the learner will be able to:
- Understand the role of the MMEL as the basis of the MEL for an aircraft type.
- Know under which conditions an aircraft may fly with inoperative equipment. 
- Identify the operations and maintenance responsibilities related to applying the MEL. 

Teaching method

Study of the regulations.
Real-world examples.

Target audience

Flight crews.
Cabin crews.
Air operators and private operators.

Assessment

Multiple-choice assessment.
A certificate of completion.
A personal certificate of completion is issued at the end of the training. It can be added to the learner's training record in line with the operator's policy. 

Contents

MMEL policy and procedures, including revisions.
MEL development for operators and type certificate holders, including approval and administration processes.
MMEL/MEL regulatory basis (EASA, FAA).
​

Reading and interpreting a MMEL and a MEL.

Responsibilities (authorities, manufacturer, operator).

​Process for developing and approving an operator MEL. 

Benefits 

- Understand the role of the MMEL and MEL in flight safety, use minimum equipment lists better day to day, and reduce operational errors related to inoperative equipment.
- Decide faster whether a flight can safely go ahead with a failure.​

- Reduce MEL interpretation errors in operations or maintenance.

- Strengthen compliance with EASA/FAA requirements for inoperative equipment.

Prerequisites

Basic knowledge of flight operations or maintenance, or operational experience in an airline or a Part-145 organization.

RECOMMENDED FURTHER TRAINING

To go further and strengthen your regulatory and operational skills around the use of the MEL, we recommend the following courses, also available on Aero Consulting Online. 

  EASA Part-CAMO - Continuing Airworthiness
Maintenance programme and continuing airworthiness management.
Why? For teams in charge of maintenance programmes and airworthiness monitoring, so that MMEL/MEL constraints are properly built into planning.

Frequently asked questions about the MMEL & MEL training

1. What is the MEL & MMEL training?

The MEL & MMEL training explains how the Master Minimum Equipment List (MMEL) and the Minimum Equipment List (MEL) work: two regulatory documents that define the minimum equipment required for an aircraft to fly safely with certain equipment inoperative.

2. What is the difference between the MMEL and the MEL?

The MMEL is a generic document approved for a given aircraft type. The MEL is each operator's own operational version, developed from the MMEL and approved by the competent authority.

3. Who is this training for?

It is intended for flight crews, cabin crews, air operators and private operators who want to master the day-to-day use of the MEL.

4. Is the certificate recognized by aviation authorities?

Yes. The personal certificate issued after the multiple-choice test is signed by a qualified instructor and accepted by the authorities (DGAC, OSAC) as evidence of training during audits.

5. How does the training work?

The training is 100% online, in English. It includes 1 video and supplementary documents, for a total duration of about 40 minutes. A certificate of completion is issued at the end of the course. 

6. How much does the MEL & MMEL training cost?

The MEL & MMEL online training costs €50. Access is immediate after sign-up and payment.

7. Which topics does this training cover?

The training covers the legal basis of the MMEL/MEL, MMEL policy and procedures (including revisions), and MEL development for operators, including approval and administration processes.

8. Can an aircraft fly with inoperative equipment?

Yes, under certain conditions defined in the MEL. For each inoperative item, the MEL specifies the operating conditions and maintenance procedures to follow to maintain the required level of safety.

9. Which further courses are recommended?

We recommend the EASA Part-145, EASA Part-CAMO, ETOPS, Part-145 Human Factors & SMS, CRM and LOSA courses, all available on Aero Consulting Online.

10. Can I take the training from any country?
