SunExpress Goes Live with AMOSeTL

Swiss AviationSoftware (Swiss-AS) has announced that SunExpress, a joint venture between Lufthansa and Turkish Airlines, has successfully gone live with AMOSeTL, the fully integrated
Electronic Tech Log solution within AMOS. This milestone marks the culmination of an intensive two-year collaboration, with SunExpress being not only the launch customer but also as a strategic development partner contributing to the product’s refinement. Since the initial development phase of AMOSeTL in 2022, SunExpress has actively participated in workshops, demos, and feedback sessions, contributing valuable insights that helped shape the product. The airline’s commitment to innovation and operational excellence was instrumental throughout all phases of the project.

A phased journey from concept to paperless cockpit

SunExpress was among the first airlines to sign for AMOSeTL. Their operational
expertise and commitment to digitalization provided vital input throughout the project. The objective: to deliver a modern, intuitive, and fully integrated electronic tech log solution that meets the
operational needs of airlines and supports their paperless ambitions.

AMOSeTL was rolled out with AMOS release 23.12, following a structured approach supported by close cooperation between SunExpress and Swiss-AS. A “parallel run” phase was launched in April 2024, followed by the fleet-wide iPad rollout in June. During this time, the AMOS Competence Centre, pilots, and engineers carried out extensive testing. Valuable feedback collected from all user groups was continuously integrated into the product, further enhancing its usability and robustness.

By working closely with Swiss-AS, SunExpress also secured approval from the local aviation authority to operate AMOSeTL. This was a significant milestone, supported by the creation of tailored documentation for troubleshooting and user guidance. Once the logged and operated flights reached a stable high-performance level—covering approximately 101,000 flights—the decision to off-board paper tech logs was confirmed. A staggered deployment began in January 2025, starting with the Boeing 737-8 fleet. Within three months, the entire SunExpress fleet was transitioned smoothly to fully paperless operation.
