FAQs

This checklist covers ECS certification requirements related to EASA CS-23 (Normal-Category Aeroplanes), CS-25 (Large Aeroplanes), CS-27 (Small Rotorcraft), and CS-29 (Large Rotorcraft) certification specifications.

This checklist should be used by ECS design engineers, certification specialists, airworthiness inspectors, and regulatory compliance officers involved in the certification process of aircraft environmental control systems.

The checklist addresses areas such as cabin pressurization, temperature control, air quality and circulation, system redundancy, failure modes and effects analysis (FMEA), and integration with other aircraft systems as required by the applicable EASA certification specifications.

By ensuring that ECS designs meet all regulatory requirements, this checklist helps prevent potential safety issues related to cabin pressure, air quality, and temperature control, while also ensuring optimal passenger comfort during flights.

This checklist should be used throughout the ECS design and development process, from initial concept to final certification. It's particularly crucial during the detailed design phase, system integration, and pre-certification testing stages.
