Expanding Role of Aircraft APUs in Modern Aviation Drives the Global Market Growth
An Aircraft Auxiliary Power Unit (APU) was once relegated to the basic function of providing pneumatic and electrical power to aircraft while on the ground, but the role and capabilities of APUs have changed dramatically. Today's APUs sustain several operational workloads, which consist of powering avionics while performing pre-flight checks, powering systems to provide comfort while in the cabin, and finally modifying the operational need for ground power units (GPUs). In many cases, APUs within modern aircraft enabled hybrid-electric propulsion systems and provided emergency backup power, capabilities that were designed to enhance operational efficiency and safety. APUs also provided opportunities for reduced engine wear by eliminating ground idle times and improving ETOPS operations that are enhanced by redundancy. Overall, APUs are now designed with environmental responsibility in mind, as aviation strives for lower aircraft emissions and lower fuel consumption, making them a growing component of the professional aviation workload.
For instance, in March 2025, RTX Corporation entered into three agreements with JetZero, the developer of a novel blended wing body aircraft, to provide key systems for the airframer's full-scale demonstrator.
