Companies nowadays must react fast to changing conditions in a global market. We encourage and support our engineers to tread new paths.


People sit up to 18 hours in an aircraft. How can light contribute to the passengers' wellbeing? How can flying be made an experience?
“Besides grades, we are even more interested in questions like: Does the applicant suit Diehl?”

Dual training as the foundation of working life

In many organizations, only those applicants who have excellent grades and present themselves convincingly during the personal interview win the race. Naturally, good grades are required at Diehl as well and are helpful, however, we are not looking primarily for a perfect presentation: “We look for applicants that fit to Diehl, a family owned business, and are happy to face the daily challenges in working life at Diehl. That is young people who find our company culture appealing, and ideally would like to spend their entire working life with us”, Johanna Prottengeier, Specialist Assistant at Diehl Ausbildungs- und Qualifizierungs-GmbH (DAQ) points out making the expectations of the organization clear.

Impressions from our vocational training

Our profound education provides the basis for a long-standing and successful career.

Diehl takes considerable efforts to prepare their young talents optimally to tackle the future challenges. Besides imparting the necessary professional know-how, support is also provided for personal development, e.g. through joint campaigns and seminars, company visits and study tours. And – as the traditional highlight of the training – a trip to Berlin to learn more about political processes and the most important institutions of our country.

A fundamental success factor during the training is the close relationship between the trainers and their trainees. “This does not suggest any obtrusiveness but a benevolent participation in the development of a young human being”, says Johanna Prottengeier. “Our experienced trainers can specifically enhance the strengths of the trainees and provide consistent help to overcome their weaknesses. Besides imparting corporate knowledge, they also practice the values of the Diehl family business”, says Johanna Prottengeier, who herself started as a trainee at Diehl. 

The traditional high value placed on the company anniversaries at Diehl is based, not least, on the consistent support given to young professionals at the beginning of their careers. “We take our trainees seriously with respect to their personal development. Therefore, we also expect in turn team spirit, respectful behavior, and long term commitment”, Prottengeier states. “It is important at Diehl to help not only the usual dual trainees and dual university students, but also -especially in recent times -young

Factory of the year – fully automatic, highly efficient and flexible

In October 2015, the Wangen location of Diehl Controls was chosen as the overall winner of the renowned industry benchmark contest: "Factory of the Year/Global Excellence in Operations (GEO)".*

More product handling, less power consumption at the "Factory of the year 2015".

Optimization of circuit-board assembly in every respect was decisive for the jury's decision. The fully automated assembly line comprises 72 modules over a length of 86 meters. It is operated by four employees per shift with an annual output of 1.2 million circuit boards. The facilities are monitored by cameras, the results are collected digitally.

On this basis, Diehl Controls Wangen achieved impressive dynamic improvements between 2011 and 2014: the finished-product volume rose by 10 percent and the value generated increased by 95 percent whereas power consumption dropped by 13 percent.

"From development to supply chain to production, we have succeeded in continously improving all processes and increasing the level of automation. With this approach, we are able to meet global competition," says Katrin Franke, Operations Director Electronics at Diehl Controls.

Light Verification Center

The Light Verification Center of Diehl Aviation has a floor space of more than 1000 sq m. It is the largest facility of its kind in Germany where the effect of light in aircraft cabins is tested. Passengers are to constantly feel comfortable during up to 18 hours of flight. "Cabin lighting is of great importance for a person's biological clock, and the service crew uses lighting to structure the flight phases. That means for us: every flight phase must have appropriate cabin lighting," Dirk-Achim Schevardo explains.

Depending on the respective cultural origin, light is perceived in different ways and so we adapt it to the airline’s wishes: "Scandinavian airlines like warm, bright light; in the Asian region, cooler, bluish light is preferred" Schevardo describes the different tastes. In this context, the surfaces reflecting the light are decisive. "We try to "paint by light": that means all surfaces should be illuminated evenly."

In top-of-the-range aircraft construction, designers use select materials and want to stage them appropriately. Dirk-Achim Schevardo remembers a customer who wanted to accentuate a particular kind of wood veneer: "However, dark wood absorbs a huge amount of light and thus requires a specially adjusted light source. We see ourselves as a link between engineers, designers, marketing experts and businessmen. This is of particular importance if the customer cannot describe his problem in detail."

Aircraft Projection System

  • Diehl Aviation regularly shows at exhibitions what is possible in aircraft cabins:  

Diehl Aviation is known as a supplier with highest quality standards. This is what matters in our sector: “It is important to us that lights can be replaced rapidly and our high quality standards ensure a low failure rate. Nevertheless, we want to sell the light effects in the cabin, not the technology as such or individual lamps. The amount of effort we spend on that guarantees the best results for our customers.” 

In order to show the multiple effects of light in the cabin, our employees check the customer's requirements in detail: "Light can make flying an experience again. We offer design workshops to show what is possible. In the cabin roof or in a light dome, we make emerge a starry sky, the airline's logo or duty-free products. 

The success of Diehl Aviation proves us right: “All Airbus aircraft and almost the entire Boeing aircraft family are equipped with Diehl lighting systems,” Dirk-Achim Schevardo proudly states.
