EASA grants ESG STC for the installation of 3G/4G mobile communications and cabin Wi-Fi in helicopters

ESG enables Internet in helicopters and expands its range of aviation services with state-of-the-art special equipment for EC135 and EC635.

This May, the European Union Aviation Safety Agency (EASA) approved ESG Elektroniksystem- und Logistik-GmbH for the new Supplemental Type Certificate (STC) "Installation of a cabin Wi-Fi hotspot with 3G/4G cellular modem and outside antennas" for the EC135 and EC635 helicopters.
In order to achieve the approval, comprehensive ground and flight tests were carried out. It was essential that interference with the helicopter could be excluded for all mobile radio frequencies. A software developed by ESG is installed on the Wi-Fi router integrated in the helicopter for the customer, which not only enables Internet connection as such, but also secure access to networks of public authorities and companies. The corresponding interface can be configured according to customer requirements.
This ESG solution package has opened up numerous promising applications both in the context of specific police deployment scenarios and in the field of rescue services or for use in private or business situations: protected
transmission of police mission data, real-time transmission of sensitive patient information, "working in flight" or infotainment in helicopter shuttles.
The STC issued by the EASA also allows for a comparatively fast transfer to other helicopter types. This in turn creates added value for a wide range of customers in the short term. This once again underscores ESG's
performance and innovative strength as an aviation company for specific operational and special systems.
