Test Services

We offer a series of test services to ensure that our technical components always perform, flawlessly, even in the toughest of conditions of aerospace.

In addition, our in-house teams evaluate how humidity, temperature, and electrical fluctuations impact parts as well as equipment during air travel.

Temperature Humidity Chamber

Aerospace components are exposed to extreme conditions during flight including quick temperature changes, which effect humidity levels as well. We conduct fully automated and individual temperature and humidity tests in our temperature humidity chamber as well as parallel electrical tests to guarantee dependable operation

Electrical Tests

Electrical components installed in aircraft are exposed to all types of conditions, including changes in frequency and power, power interrupts and or spikes. AES performs extensive electrical tests for these specific situations. Naturally, all our tests are ABD-compliant and fulfil the RTCA DO-160 standard.

Associated with the ZARM Test Center

AES works closely with the ZARM Test Center that is also located in Bremen. This close cooperation extends our variety of qualification and test services. With its broad range of aerospace testing capabilities in vacuum, in extreme and variable thermal environments, under vibration, as well as in hyper- and microgravity you can rely on comprehensive qualification services for your products.

Law and Order at AES – join our Aviation Legislation Training Programme. AES organizes training programs to help aviation companies understand the finer points of aviation legislation. Are you familiar with the responsibilities of the German National Civil Aviation Authority (LBA) and the European Aviation Safety Agency (EASA)? What are the duties and responsibilities of the ICAO? Do you know which EU rules and acts are relevant to your business?

AES teaches both management and certified employees things they need to know about aviation legislation. Take part in our training courses to find out the answers to these questions and benefit from our knowledge in aerospace.

We offer two different Aviation Legislation Training courses in German language, which vary in complexity and detail. The training programme is designed for approx. 10 participants. A handout along with various group exercises help attendees absorb this fascinating and helpful information.

1. Aviation Legislation Training for Component Certification Experts

Our certification staff training runs for approx. 3 days. All participants take an exam roughly 4 to 6 weeks after the course. Each participant, who successfully passes the exam, receives a certificate of participation.

2. Aviation Legislation Training for Management

We offer a more condensed version of the training course for management employees. The training course runs approx. 8 hours and does not have an exam.

Topic overview:

  • Laws, decrees, and edicts
  • Administration of air traffic
  • ICAO
  • Design, development, and sample testing
  • Approval of samples and modifications
