Flight and Engine Control Systems

Diehl Aviation stands for powerful, safe, and durable avionics solutions that meet the highest requirements for functionality and system integrity. The company develops engine and flight control systems that are used directly on the aircraft and integrates complex hardware and software solutions into fly-by-wire architectures.

The systems are characterized by:

• Robust, deterministic design that reliably covers all operating conditions
• Redundancy concepts and integrated monitoring that ensure maximum operational safety
• Flexible software solutions that can be adapted to different engine and flight control parameters
• Comprehensive qualification according to international standards such as SAE ARP4754, SAE ARP4761, RTCA DO-178, RTCA DO-254, and RTCA DO-160
• High operational reliability thanks to intensive stress testing during production

With its many years of experience, Diehl Aviation meets the high delivery and availability requirements of aircraft manufacturers and ensures that both classic commercial aircraft and innovative eVTOL platforms can be operated reliably and efficiently.

Manufacturers and operators benefit from high reliability and easy integration. The systems enable high delivery and availability rates, reduce operational risks, and ensure long-term efficient and safe flight operations.

Flight Control Systems

For fly-by-wire aircraft, Diehl Aviation supplies solutions for primary and secondary flight controls – for commercial, cargo, and military aircraft, right through to eVTOL systems.

System components and features:

• Flight Control Computers (FCC): High-performance computers for precise control of slats, flaps, rudders, and elevators
• Actuator Control Electronics (ACE): Interface of the fly-by-wire system for sensors and actuators
• Slat/Flap Control Computer (SFCC): Control computer for the high-lift system

Benefit

Aircraft manufacturers work with Diehl Aviation to develop the basis for aircraft certification using an established development process. Airlines receive powerful, reliable, and maintenance-free control systems that incur extremely low maintenance costs.

Flight control for advanced air mobility

For eVTOL aircraft, Diehl Aviation provides integrated fly-by-wire systems and computer platforms for controlling flight attitude and lift.

Exemplary applications:

• Fully digital control of 18 rotors
• Fly-by-light bus system for lightweight, reliable communication
• Flexible software integration for fast development and certification times
• Robust, compact architecture for limited space

The solutions combine maximum safety, reliable performance, and short time-to-market for innovative aircraft concepts.

Benefit

Operators and manufacturers benefit from short development times, high safety, and stable performance. The systems enable efficient integration into new aircraft concepts and reduce risks during market launch and operation.

Engine Control Systems

Diehl Aviation develops and produces specialized engine controllers for auxiliary power units (APUs). APUs provide electrical power and compressed air during ground operations and enable the main engines to be started.

Key functions and features:

• Line Replaceable Units (LRU) according to ARINC standard for easy installation and replacement
• Digital and upgradeable via software upload
• Integrated overspeed protection for reliable turbine safety
• Software-based engine parameterization for flexible adjustments throughout the entire life cycle
• Development and qualification according to Design Assurance Level (DAL) A

Benefits

Operators and manufacturers benefit from maximum reliability, extremely long life cycles, and minimal maintenance. This reduces operating costs and ensures continuous flight readiness.
