How to Understand Aviation Starting Units’ Voltage Ranges


Summary: Starting units are powerful aviation tools that can provide additional power when needed.

When it comes to selecting the right type of battery packs for your aircraft, aircraft start units are the ideal solution when it comes to the majority of models. With an enhanced design, it can immediately start an aircraft ranging from a small commercial plane to a major business airplane. These starting units are powerful, durable, and efficient for use. Here is a brief overview on what you need to know when it comes to choosing the right starting unit for your plane.

How to Find a Starting Unit

When finding a portable power supply for your aircraft, the first thing that you’ll need to know is that it comes in a range of voltages (12V, 24V, and 28V). It’s not only important that you choose the right one, but you need to consider what you are going to use the starting unit for. Do you need it solely for emergency purposes, or will you be using it multiple times throughout the day? By figuring this out, you’ll be able to narrow down which unit will work best with your lifestyle.

Discussing the Voltage of Starting Units

This is only the first step, you’ll also need to understand the various voltages. It’s highly recommended that you speak to a specialist in the department that you are purchasing from to ensure that it’ll function correctly with your aircraft. Although this piece of aircraft maintenance equipment is enough for an aircraft, there are certain cases where additional power is needed. Speak with a specialist in regards to this.

For small aircraft, the voltage requirement that you’ll need is 12V. There are various sizes and models, however the larger sizes are normally for larger aircrafts. Standard DC powered aircraft require 24V DC to start up. Most of the designs have a 24V battery within, therefore it requires a 24V unit to start. Now, when it comes to these units, you have choices. You can purchase a portable unit, or you can have one that is attached to a large trolley cart. 28V units are also available – although many of these are sole with the purpose of having peace of mind, as most aircraft will start up with a 24V current. However, there are a few aircraft models that are volt sensitive and will require a 28V unit to start. Discuss this with an expert beforehand so you won’t have any difficulties when using it.
