The EWIS (Electrical Wiring Interconnection Systems) is essential for aviation safety, since it connects all the electrical systems of an aircraft: wiring, connections, splices, terminals, etc.
This system ensures that everything works correctly during the flight, but electrical problems, such as damaged cables or faulty connections, are one of the main causes of incidents. A failure in EWIS can have very serious consequences, from short circuits to fires or progressive degradation of control systems.
In this article we are going to explain what EWIS systems consist of, how AI is improving predictive maintenance and the importance of aeronautical training.
What is an EWIS system and why is it critical?
EWIS refers to the set of interconnected wiring, joints (bundles), terminals, splices, retaining supports, insulation, electrical protection systems, etc.
The reliability of the entire aircraft depends, to a large extent, on this system working perfectly. However, EWIS are subject to constant stress: vibrations, sudden changes in temperature, humidity, friction or aging of the insulation. Over time, small imperfections can become serious failures capable of compromising flight safety.
Problems in EWIS have been identified as causes or contributing factors in serious incidents, which is why aviation regulations impose inspections, scheduled maintenance and specific safety procedures.
How Artificial Intelligence revolutionizes EWIS maintenance
Traditionally, electrical maintenance on aircraft has been based on visual inspections, periodic tests and scheduled replacements. This is a valid approach, but reactive: the failure may be incubating long before the human eye or a standard test detects it.
Thanks to Artificial Intelligence (AI), the paradigm changes completely. It is now possible to talk about predictive maintenance, that is, anticipating problems before they appear.
Advances in sensors and processing capacity make it possible to continuously monitor key parameters such as the resistance of a cable, the temperature of a connector, humidity in a critical area or even vibration patterns that could indicate premature wear. All this information, which was previously lost, is transformed into data that artificial intelligence interprets.
Machine learning algorithms (Learning Machine) analyze trends, compare with previous models and are capable of identifying the beginning of an anomaly when it is still invisible to the naked eye. In some cases, they even predict how much useful life a component has left before it fails.
All of this allows:
- An increase in reliability and reduction of operational incidents.
- Less unplanned downtime.
- Cost savings: fewer spare parts, fewer hours of rush work, fewer cancellations or delays.
- Safety improvement: prevent electrical failures that can affect various systems (instrumentation, communications, lighting, etc.).
For airlines, every hour that a plane remains on the ground due to an unplanned breakdown means thousands of euros in losses. AI applied to the maintenance of EWIS systems helps minimize that risk.
Specialized EWIS training
The existence of this technological revolution implies that the professional profile in demand is changing. It is not enough to know about traditional maintenance: it is essential to train in emerging technologies applied to EWIS.
At Segu-Aero we offer you 2 online courses: Initial EWIS or Recurrent EWIS.
These EWIS aviation training programs cover:
- Maintenance of electrical and interconnection systems (EWIS) with a focus on diagnosis and failure prediction.
- Practical projects that allow working with real/simulated data for anomaly detection.
- Regulations associated with EWIS maintenance, certifications and applicable aeronautical standards.
If you are a maintenance technician, aeronautical engineer, inspector or professional in the electrical area of aircraft, training with Segu-Aero in EWIS will provide you with exclusive skills that are increasingly in demand.
In summary, artificial intelligence applied to the maintenance of EWIS systems is not science fiction: it is already an operational necessity. It allows you to anticipate electrical failures, improve reliability, reduce costs and increase aviation safety standards.
The key is to combine this technology with well-trained professionals, robust processes and a clear regulatory approach. Training like the one we offer at Segu-Aero in EWIS maintenance and emerging technologies is essential to keep up with the standards of modern aviation.
