Electrical load analysis

Electrical load analysis (ELA)

Our service enables you to fulfill the request of the authorities and aircraft manufacturer (OEM) to maintain and update the ELA after each electrical modification. These changes must be analyzed to ensure and maintain the electrical load integrity of the aircraft electrical distribution system. You as CAMO are responsible for the safety of the changes made – we help you with the necessary documentation.

We offer a one time ELA calculation or a continuous service to have your ELA status always up to date and available live and in real time.


Your benefits

Efficient calculation of the entire electrical system and proof of aircraft safety under all operational cases

Compliance with authority and OEM requirements

Standardized ELA documentation and archiving also for mixed fleets

No internal ELA expert knowledge required

Precise electrical load calculation including remaining power capacity

Continuous data management with live and real-time ELA status
