- AMOSeTL fully deployed across the SunExpress fleet after a staggered rollout that began in January 2025
- Over 101,000 flights logged during the parallel run phase, paving the way for confident transition to paperless operations
- Successful two-year collaboration between SunExpress and Swiss-AS shaped the product from early development to authority approval and go-live
Swiss AviationSoftware (Swiss-AS) is pleased to announce 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 digitalisation 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.
Scope and integration
SunExpress implemented AMOSeTL in both pilot mode and external maintenance mode, fully integrated with AMOSmobile/EXEC at its base stations. This setup allows for seamless collaboration between cockpit and maintenance teams, fully digitalising the technical logbook process from end to end.
Together, AMOSeTL and AMOSmobile/EXEC provide a modern, connected working environment: pilots can log defects and monitor aircraft status directly on their devices, while engineers receive real-time updates and can take immediate action using AMOSmobile/EXEC.
With this setup, SunExpress has achieved a truly paperless operation across its fleet. From pre-flight checks to return-to-service confirmations, every step is now handled digitally – reducing administrative overhead, ensuring data accuracy, and improving turnaround times.
Now fully operational at SunExpress, AMOSeTL enables:
- Operational efficiency: Real-time synchronisation of cockpit and maintenance data, accelerated defect reporting, and streamlined return-to-service workflows.
- Digital progress: Accurate, transparent process execution and improved data quality through structured, digital logbook entries.
- Improved working environment: A modern, paperless interface tailored to pilots and engineers.
- Resilience: Reliable operation even without internet connectivity thanks to AMOSeTL’s offline mode.
- Sustainability: A paperless cockpit contributes to the airline’s environmental goals.
AMOSeTL is part of Swiss-AS’s commitment to supporting the digital transformation of the aviation industry by offering solutions that connect cockpit, maintenance, and operations in a seamless digital workflow.
