Liebherr has acquired an unrivalled experience in designing on-board electronics for the control and monitoring of highly integrated, flight-safety critical and complex systems.

For over 30 years, more than 20,000 electronic units designed and manufactured by Liebherr have demonstrated their outstanding in-service reliability on board commercial and military aircraft, helicopters as well as business jets in ATA chapters such as ATA 21, 30, 36 (air management, ice protection, pneumatics), ATA 24 (electrical power), ATA 27 (flight controls), and ATA 32 (landing gear).

Liebherr supplies these electronic units with embedded software, both as standalone units, or as part of the company's air management, flight control and landing gear systems. In terms of hardware development, qualification and production for signal and power circuits, Liebherr-Aerospace benefits from the Liebherr Group’s competence center for electronics in Lindau (Germany).

The world class standalone electronic products developed by Liebherr as an integral part of a flight control, air management or landing gear system can also be applied for multiple other applications on an aircraft. Different ATA chapters as for example power or equipment/furnishing can also benefit from the tremendous Liebherr expertise in power and signal electronics.

Signal Electronics

Liebherr’s signal electronics have demonstrated their ability to fulfill the highest criticality missions when so requested by the aircraft manufacturers, like for example for primary flight control computers or for engine bleed air computers.

The control software can be hosted by dedicated controllers designed and manufactured by Liebherr or by IMA modules as selected by the aircraft manufacturer.
