Certification of aeronautical systems: plans, analyses, tests and certification reports
Plans, analyses and compliance reports against ANAC, FAA and EASA airworthiness requirements. We issue the certification documents ourselves; you review them and submit them to the authority.
Experience in all phases of the certification process of air conditioning and pressurization (ATA 21), ice and rain protection (ATA 30) and pneumatic systems (ATA 36), with ANAC, FAA, EASA, JCAB and Transport Canada. Some of our members worked for years as professionals accredited by ANAC to issue technical opinions on compliance.
- Akaer, ASOJ TA, 2020 to 2024ECS, supplemental cooling and ice protection: design, laboratory, ground and flight tests, and certification reports.
- Embraer E2, 2014 to 2018Pneumatic system: design, system description (ATA 36), component qualification, ground and flight test proposals and certification reports submitted by the customer.
- ATA 21, 30 and 36Certification work accepted by ANAC, FAA, EASA, JCAB and Transport Canada.
- Embraer, 1997 to 2007Design and certification of wing and air data probe ice protection, E190 pneumatic, ECS and icing certification.
- Smart probes, Embraer 170/190, 2003 to 2004Certification after an EASA CRI, with conditions that reached TSO-C16b more than a decade later.
- eVTOL certification supportAir data probe icing (Joby) and 2D ice shapes following EUROCAE ED-314 (Vertical).
- SAE AC-9CATS is the liaison to the aircraft icing technology committee, with frequent contact with the authorities.
Complete packages, from requirements to certification reports
We prefer whole, long-term programs to isolated tasks: ATS responsible for design support, tests and the certification documents.
What a package covers
Certification basis and means of compliance, system description, safety assessment, certification plan, test proposals, component qualification review and the compliance reports. We issue these documents ourselves, from analysis or test results. You review them and submit them to the authorities. This is our differentiator.
One team for the whole program
At least one associate senior engineer stays assigned from the first requirement to the last report, so decisions, test points and evidence stay consistent. When needed, an engineer works full time on site with your team.
An example: Akaer, ASOJ TA
2020 to 2024. A four-year complete package outsourced by Akaer to ATS for supply to Turkish Aerospace: ECS modification of the Global 6000 for the surveillance variant per 14 CFR Part 25, a supplemental liquid cooling system designed from scratch, ice protection, laboratory, ground and flight tests, and all certification reports ready for submission.
Need only a part? We define the scope with you.
What you receive
Certification basis and means of compliance
Applicable requirements for the system and how each one will be shown.

Certification of aeronautical systems
Ensuring aeronautical safety
The certification of aeronautical systems and an aircraft aims to ensure that the aircraft and its systems, which are highly integrated, fulfill the functions for which they were properly and safely designed. The technical requirements applicable to an aircraft and its systems are presented in a wide set of technical requirements established by the aeronautical authorities of each country (ANAC-Brasil, FAA-USA among others) or that represent a group of countries, in the case of EASA for countries belonging to the European Union.
This technical requirements base is dynamic and is being revised due to the development of technology, new types of aeronautical products and the need to address the safety of aircraft and systems. An aircraft and its systems are considered fit for operation when the demonstration of the applicable technical requirements, performed by the entity responsible for the aircraft, are accepted by the aeronautical authority.
The certification process starts in the preliminary phases
The certification process starts from the preliminary phases of the development of the aircraft and its systems and has as main phases: establishing the certification basis, its requirements and respective modes of compliance; demonstration of compliance with requirements through technical project data, analysis (including safety assessment analysis), tests, inspections, simulations and equipment qualification; and issuance of the aircraft type certificate.
Tools, and where each one fits
Tools serve the engineering work. We say what each one does in the project.
| Tool | Role in the project | Status |
|---|---|---|
| CFD++ | Flow, heat transfer and droplet impingement analyses used as compliance evidence. | Licensed |
| AMESim, FloMaster | System models of ECS, pneumatic and cooling networks, steady and transient. | Client license |
| Femap, NX Nastran, Adina | Stress and thermal analysis of ducts and structures, including an FEA model delivered for the manufacturer's use. | Licensed |
| MATLAB | Envelope, mission and test point tools, such as air data probe envelopes and icing critical conditions. Run with the client's license. | Client license |
| Python, Nsp, Scilab | Envelope, mission and test point tools, such as air data probe envelopes and icing critical conditions. Python, Nsp and Scilab need no license and replace MATLAB when the client does not provide one. | In use |
| Excel/VBA | Envelope, mission and test point tools, such as air data probe envelopes and icing critical conditions. | Licensed |

Questions engineers ask before they hire us
Which certification documents do you issue?
We issue the documents the program needs, from analysis or test results: system description, safety assessment inputs, certification plan, test proposals, test reports and compliance reports. You review them and submit them to the authority.
Who submits the documents to the authority?
You do. The applicant or design organization holds the certification and submits the evidence. We work inside your process and deliver documents ready for submission.
Which systems and authorities do you cover?
Air conditioning and pressurization (ATA 21), ice and rain protection (ATA 30) and pneumatic systems (ATA 36), with ANAC, FAA, EASA, JCAB and Transport Canada, on civil, military and eVTOL programs.
Can simulation be part of the means of compliance?
Yes, as analysis evidence, when the model is validated and its use is agreed in the certification plan. Simulation also reduces the number of test points, and tests confirm the points that matter.
Can you work on site with our team?
Yes. On component qualification for an air management system, an ATS engineer worked full time on site to keep the interface with suppliers smooth.
Is our data kept confidential?
Yes. We work under NDA, and your design data and reports stay with you.
