Aerospace and eVTOL Testing -
Advancing Flight and Safety

Avionics testing ensures passenger safety and sustains the future of the aviation industry. Innovation and accuracy are imperative, as modern avionics systems rely on precise measurement data for practical and complex simulations. Aerospace and evTOL testing validates components and evaluates performance through several approaches. Ground testing evaluates components in a controlled setting, while structural testing ensures durability. Flight testing confirms capabilities through real-world maneuvers, enhancing flight characteristics after simulation and ground phases.

Simplicity and Maximum Flexibility in Recording and Analyzing Aircraft Parameters

In aviation, flight test instrumentation is crucial for gathering essential measurement data and parameters required for certification by aviation authorities. Diverse technologies and tools decode and interpret data during flight trials, offering a detailed overview of an aircraft's performance.

Key components include the flight recorder, analog sensor data, switching states, field bus info, and communication protocols like ARINC 429, ARINC 664, or MIL-STD-1553B from the flight control system. The flight control system manages maneuverability and stability, with flight test instruments capture data on control surface configurations, response times, and flight dynamics. Engineers use these measurements to optimize performance and safety.

An aircraft manufacturer's ‘Flight Test Instrumentation’ division uses data acquisition systems (DAS or DAQ for short) whose task is to record analogue sensor data. Such systems record several hundred to a thousand measurement channels, the most common sensors being strain gauges and sensors for measuring temperature or vibration. Force, pressure, displacement, angle and flow sensors are also used. In addition to recording the analogue signals, the digital data of the avionics system must also be recorded synchronously. To do this, digital interfaces such as ARINC or MIL-Bus must be able to be read and decoded by the DAQ system.

Aerospace ground equipment acts as an intermediary, enabling real-time communication, data stream monitoring, and seamless information exchange between the aircraft and ground operations. This facilitates reviewing and replicating flight maneuvers, enhancing test process flexibility and adaptability.

Measurement data can be stored within the flight test measurement system or on the flight test engineer's workstation, or transmitted directly to a ground station via IRIG 106 telemetry standards. Aerospace ground equipment includes a reception antenna for telemetry signals, a system for PCM data stream decoding, and the capability to route distinct measurement data to separate workstations. This integration enhances communication and monitoring, streamlining the flight testing process.
