APUs: Little Engines That Could (But Prefer to Work Behind the Scenes)
While parked on the ground, fixed- and rotary-wing aircraft rely on auxiliary power units (APUs) to start and power aircraft systems without taking the aircraft into the sky. APUs are fully capable small engines that could, if needed, assist with crucial functions during flight. From aircraft apu to heavy-duty truck applications, these versatile power sources ensure peak efficiency across diverse equipment types.
