What is RMT in Aviation? (Rule Making Task (Easa))

Rule Making Task (RMT) is a vital process in the aviation industry, ensuring the establishment and maintenance of safety regulations. RMT is the responsibility of the European Union Aviation Safety Agency (EASA), which plays a crucial role in formulating aviation rules and standards for the European Union (EU) member states. This article delves deep into the significance of the rule making task carried out by EASA and its impact on aviation safety.

EASA, established in 2003, is an agency of the European Union responsible for civil aviation safety. With its headquarters in Cologne, Germany, EASA works towards harmonizing safety standards and regulations across Europe. The agency’s primary goal is to ensure the highest level of safety and environmental protection in civil aviation.

In order to achieve this objective, EASA has developed the Rule Making Task (RMT) process, which allows the agency to establish new or amend existing regulations. The RMT process involves thorough research, analysis, and collaboration with experts and stakeholders to make informed decisions regarding aviation safety requirements.

The Importance of the Rule Making Task

The Rule Making Task (RMT) conducted by EASA is of utmost importance to the aviation industry as it ensures the continuous improvement and standardization of safety regulations. Let’s explore some key reasons why RMT is essential:

1. Enhancing Aviation Safety

By undertaking the Rule Making Task, EASA assesses the existing regulations and identifies areas that require improvement to enhance aviation safety. The agency works collaboratively with stakeholders, including airlines, aircraft manufacturers, and aviation authorities, to develop and implement new regulations or amendments.

For instance, the EASA RMT.0016 Task focused on the introduction of new requirements for the maintenance of aircraft cabin air quality. This rule making task aimed to mitigate health risks for passengers and crew members associated with exposure to contaminated cabin air.

Through its RMT process, EASA ensures that safety risks are identified, analyzed, and addressed effectively, leading to a safer aviation environment for all stakeholders.

2. Harmonization of Regulations

The European Union consists of multiple member states with their own national aviation regulations. The Rule Making Task carried out by EASA is crucial in harmonizing these regulations to create a unified aviation system across Europe.

Through the RMT process, EASA develops regulations that are applicable to all member states, ensuring that safety standards are consistent throughout Europe. This harmonization simplifies operations for airlines, aircraft manufacturers, and other aviation entities, reducing the administrative burden associated with complying with diverse national regulations.

For example, the EASA RMT.0632 Task aimed to harmonize the certification process for the installation of avionics systems in aircraft. By establishing common rules and procedures, this RMT reduced the complexity and costs associated with certifying avionics equipment, benefiting manufacturers and operators alike.

EASA’s Rule Making Task Process

EASA’s Rule Making Task (RMT) process is a comprehensive and systematic approach to developing or amending regulations. Let’s take a closer look at the step-by-step process of an RMT:

1. Identification of Safety Issue

The first step in the RMT process is the identification of a safety issue or a regulatory need. This can be initiated by EASA itself, in response to emerging safety concerns, or through a request from stakeholders or member states.

For example, the EASA RMT.0230 Task was initiated to address safety concerns related to engine surge and stall events in helicopter operations. By identifying this safety issue, EASA aimed to enhance the safety and performance of helicopters in Europe.

EASA conducts extensive research and analysis to fully comprehend the safety issue and its potential impact, ensuring that the subsequent rule making task addresses the problem effectively.

2. Stakeholder Consultation

Once the safety issue is identified, EASA engages in a collaborative process by consulting with stakeholders, including industry experts, national authorities, and the general public. This inclusive approach allows for diverse perspectives and expert opinions to be taken into consideration during the rule making task.

Stakeholder consultation is essential to ensure that the proposed regulations are practical, feasible, and can be implemented effectively. It also helps in identifying potential challenges and exploring different approaches to address the safety issue.

3. Development of Proposed Rule

Based on the inputs gathered during stakeholder consultation, EASA develops a proposed rule. This rule aims to address the identified safety issue while considering the diverse perspectives and expertise provided during the consultation phase.

The proposed rule undergoes a thorough review and analysis by EASA experts to ensure its effectiveness, feasibility, and compliance with relevant international standards. This analysis includes performing cost-benefit assessments and evaluating the potential impact of the proposed rule on the aviation industry.


The Rule Making Task (RMT) undertaken by the European Union Aviation Safety Agency (EASA) is a critical process that ensures the establishment of robust safety regulations in the aviation industry. Through the RMT process, EASA enhances aviation safety, harmonizes regulations, and fosters collaboration among stakeholders.

The systematic RMT process, consisting of safety issue identification, stakeholder consultation, and rule development, ensures that regulatory decisions are evidence-based, practical, and effective. By bringing together expertise from various fields, EASA creates regulations that address emerging safety concerns and promote uniformity in aviation practices across Europe.

With its continuous commitment to rule making, EASA plays a significant role in maintaining the highest level of safety and environmental protection in civil aviation. The agency’s efforts are instrumental in creating a harmonized, safe, and efficient aviation system that benefits everyone involved in the European aviation industry.
