Summary: Auxiliary power units should not always be relied on when one performs maintenance.
Written by: Start Pac
Most airplanes tend to rely on their auxiliary power units during flight to power the onboard electronics. However, when one parks an aircraft and performs maintenance, the user will be forced to use the APU the entire time. Consider it like leaving your car on idle. When you choose to do your weekly (or monthly) inspection and maintenance, you’ll want to relieve some of the stress that you’re placing on your plane’s APU and instead let a portable power supply handle the work for you.
Letting Your APU Rest
At Start Pac, we specialize in portable power units so we understand the importance of maximizing your airplane’s efficiency. Whether it be a 24 volt power supply or a 28 volt power supply, by consistently switching to a ground power unit as an alternate source of power, you’ll be able to switch your APU off and give it a break for all the times that you’re taking care of the internals of your plane.
A Key Part of One’s Maintenance Equipment
This is a necessary benefit that most aviation enthusiasts have in their arsenal. Whilst still in the mid of a technological breakthrough, most ground power units are offering additional settings and modalities that are benefitting airplanes in a series of ways. For instance, you could find a hybrid 28 volt power supply system that runs on both gas and electricity to power your craft. This reduces the overall emission rate secreted by a typical gas-powered ground power unit.
