Choosing Which Voltage to Utilize For Your Aircraft

It’s important to understand the differences between volts within a battery system.

Almost every aircraft type requires some type of electrical energy to operate their navigation, lights, COM and NAV radio’s, intercom, and other electronic frameworks. Now, this electrical system is comprised of a batter and an alternator or generater on older aircraft. All of this is connected through meters (or kilometers on larger aircraft) of wire.

Know Your Electrical System

Even for the experienced pilot, it pays to have some fundamental information of the electrical frameworks of his or her air ship, which could be a life saver if an emergency were to occur.

Automobiles and your normal homebuilt aircraft typically runs on a 12 volt electrical system where the battery, alternator and electrical gear is intended for these voltages. In any case, other, generally larger aircrafts, have 28 volt power supplies in their frameworks.

12 Volt or 28 Volt?

The system that you will choose for your aircraft doesn’t really matter. Either the 12- or 28 volt battery pack will run reliably and operate all the equipment within the aircraft. So, at first glance, there really isn’t too much of a difference in deciding which system to utilize.

Likewise, most producers have hardware that can run on either voltage or are selectable – this is not by any stretch an issue. Be that as it may, if you wish to utilize your automobile to kick off your airplane, this necessity may guide you towards a 12 volt framework. In the case you require less weight and more cranking power for starting the engine, consider using a 24- or 28 volt ground power unit.
