While there are ways to help to cut the cost of running and operating an airport, cutting back on the number or quality of the ground power unit models you have on hand is not a good option. It also makes a lot of sense to avoid letting these get past their lifecycle before upgrading and replacing, as they are essential when the planes are on the ground.
The single purpose of a ground power unit is to provide power to the plane when the engine is off. While this may not seem like a big thing, it is essential to prepare the plane pre-flight, complete tests and checks, and to ensure the plane is ready to fly. It is also essential in operating the doors to unload or load luggage as well as to provide lighting and sound systems in the cabin when passengers are boarding and deplaning.
Fixed or Mobile
Some airports have power supplies mounted into the jetway. This allows the aircraft to simply “plug into” the fixed power supply. There are some complications with this option as all planes connected draw from the same power supply and source.
At peak use times, this can lead to voltage drops and imbalances within the system. To avoid this, airports typically also have a mobile ground power unit for some or all of their terminals.
Mobile ground power unit models are able to easily move where needed as they are mounted to small, low profile trailers. They typically run off of diesel generators also mounted to the trailer and power unit.
Maintaining Voltage
To keep the correct voltage throughout the use of the power supply from the ground power unit, the system is designed to automatically adjust and balance the power output. This allows all the necessary power to the plane even if one or more systems are in use.
These systems are also designed to detect problems in the plane’s electrical system and shut-down, preventing further issues within the plane’s electronics. These built-in features are essential in limiting the number of possible complications of having electrical problems.
It is essential for all mobile ground power unit designs and models to be dependable, rugged and efficient. The top names in the industry are used in airports around the world and in all types of conditions, giving you a good idea of the reliability you can expect for years.
