Planes, unlike cars, require some kind of jumpstart before you can get them off the ground. This is because a plane usually idles for far longer than other devices, like a car, so you’ll need to provide a jump to get the battery going. Most airfields will have at least one portable power supply on hand, but it’s more likely they’ll have a few that are rotated throughout the day. This guide will examine how jumping a plane works, and how commercial airfields do it every day.
A ground power unit needs to be able to reach the aircraft in question, so most have some kind of tug functionality. Usually, the GPU is mounted to a cart that can be attached to a truck or powered cart. The unit can be driven out to wherever it’s needed, without putting an additional expense of power.
The problem becomes maneuverability.
Let’s say a helicopter wanted to land and get a re-supply. That helicopter’s landing space is far smaller than the average craft, so a truck carrying a GPU might not fit. That’s why companies like Start Pac have begun manufacturing self-propelled power. Those carts can be maneuvered by the operator, usually driven in straight lines to go up ramps, and they can supply the necessary voltage to power whatever is needed.
28 volt power supplies have become the industry standard, but smaller craft will utilize less voltage. There are planes that can function on jumps from something as small as a 14 volt power supply, they just aren’t common to frequent fliers in commercial airports.
