Information about DLR test.
"The DLR test for aspiring airline transport pilots applying for training at the Flight Training LFT in Bremen consists of 2 parts; the basic occupational skills assessment (BU) and the company qualification assessment (FQ). The test is conducted at the German Aerospace Centre (DLR) in Hamburg. The term "occupational" skills assessment already indicates that in addition to the actual test procedure, this also includes a fundamental clarification of the suitability for working as a commercial pilot.
The primary focus of the DLR-BU is on the applicant's capacity assessment, i.e. the ability to absorb audio and visual information, three-dimensional spatial sense and the ability to cope with multiple tasks and stresses. The tasks at the DLR have been developed based on typical demands in the working environment of a pilot.
In addition, knowledge in the areas of mathematics, physics and English is also tested. In addition to basic mathematics skills, the mathematics test also assesses the ability for logical thinking.
With the physics part which includes elements of theoretical pilot training such as electrical engineering, aerodynamics, wave theory, thermodynamic links etc., DLR tests whether the aspiring airline pilot can absorb the theoretical training content at LFT and also whether he/she has a basic scientific understanding of the subject matter.
In the English test, the DLR aptitude assessors increasingly focus on the ability to use the language idiomatically in addition to general grammatical skills. The demands in the DLR English test have risen significantly in recent years, reflecting the stiffer requirements for attaining the Commercial Pilot Licence in line with the JAR training guidelines."

The psychological part is limited to a yes/no complex of questions on personality as well as handwritten answers to what are know as the 10 questions.
The date for the FQ test will be 4 to 8 weeks after the successful completion of the BU test.
"If the BU has been passed successfully, an invitation to the FQ test will be issued about 4 to 8 weeks later. The FQ test assesses the applicant's psychological profile. The DLR test typically includes the ability to work in a team, working under stress, conflict resolution and a psychological interview; in addition, a mini-screening is conducted in a simple simulator."
