Based on the requirements of a leading aerospace manufacturer a functional test system for a landing flap lever was developed. The main objective of the application was the electrical and mechanical function testing including the position detection. In addition, the integrated corner sensor was selected and the absolute position of the lever checked.

Function Test example:
- Programmable AC Source: 115V / 400Hz
- Programmable DC Power Sources: 2x 0-35V, 0-8V 2x
- Fixed voltage sources 5V, 3.3V, 15V
- Central system power supply incl. emergency stop circuit as well as internal system supply voltages
- Multifunction DAQ (16-bit, 1.25 MS / s)
DUT (Device Under Test) Communication: ARINC 429
Other communication Interfaces supported: Arinc 615A Ethernet / AFDX, ARINC 664, MIL-STD-BUS 1553MIL, Fibre channel, HS1760 / MIL-STD-1760E, AS6802 Deterministic Ethernet

For quality assurance reasons under practical conditions, Stress Screening Tests were developed for the aerospace industry. During the test, the Devices Under Test (DUTs) undergo temperature cycles ranging from -40°C to +85°C, while being subjected to multi-axis shaking. This rigorous testing methodology ensures the detection of early failures and manufacturing defects with a high level of certainty.

Test System Capabilities:
- DUT interfacing via exchangeable test adapters
- Aerospace voltage 115V/400Hz
- Flexible supply and switching of multiple DC and AC voltages to the DUTs
- Stimulation and measurement of selected signals for failure detection by using commercial off the shelf (COTS) instrument based test system
- Control of climatic chamber and shaker (HASS chamber) as a subject to test sequences
- Automated verification of all software and hardware parameters
- All test result data are stored in result files, compliant to aerospace standards, e.g. ABD0100.
- Furthermore, software tools such as KT-STAT are used for SPC analysis to simplify a continuous improvement of production quality.

To effectively test complex Avionics Equipment like the Tactical Mission Computers for the Eurocopter Tiger and NH90 programs, a universal test system was implemented, exclusively built on the concept of Commercial Off-The-Shelf (COTS) components. The foundation of this system relies on the LEON Tower, specifically designed to meet the unique requirements of the aviation industry. It enables the comprehensive testing of all system components at three different levels of depth and precision.
- LRU level (Line Replaceable Unit)
- SRU level (Shop Replaceable Unit)
- PMC module level.
The three different test scenarios each have test unit adapters connected with the standard interface of the test system.

Test System Capability:
- Function Test (FCT)
- Video Signal Test
- Boundary Scan Test
- Avionics DUT Communication
- Break out Panel

The Avionics Equipment Maintenance Test System is based on the standard LEON Tower from Konrad Technologies, which was developed for the special requirements in the aviation field. For the adaptation to the different features various test adapters are connected to the system via a Virginia Panel interface.

Test System Capability:
- Functional Test (FCT)
- Dynamic current measurements
- Upgradeable test
- Real time compatibility
- Avionics DUT Communication
- Test Adapter Interface and Test Unit Adapter (TUA)
- Break out Panel
