This ongoing programme builds on previous modernisation efforts, including a comprehensive upgrade between 2005 and 2008. Under the Armed Forces Message 2023, the current PC-7 WE project is divided into two phases, aiming to extend the aircraft’s operational lifespan and enhance simulator training for pilots.
In the initial phase, preparatory upgrades will be completed by the end of 2025 in close collaboration with Pilatus, which is leading the design, procurement, and assembly of required modification kits. Pilatus is handling the conversion of 13 aircraft at its Stans site, while RUAG will modify the remaining 14 at Lodrino, with six aircraft already returned to the Air Force as part of early implementation.
This phase includes critical updates to the cockpit and communication systems, installation of a new Traffic Alert System (TAS), and removal of the Automatic Direction Finder (ADF) systems. Avionics and antennas will be removed and reinstalled, and the aircraft’s wiring harnesses will undergo a complete overhaul, enhancing the operational readiness of the fleet.
Each modified aircraft also undergoes preventive maintenance and servicing to minimise downtime and ensure optimal availability. This modernisation plan is managed with input from both Pilatus and the Swiss Air Force, supporting uninterrupted access to the aircraft for ongoing training needs.
“All these measures ensure that the PC-7 will continue to meet the requirements of modern pilot training in the future and can be operated by the Swiss Air Force until 2040,” RUAG said. This comprehensive approach to preservation and upgrades reflects the Swiss Air Force’s commitment to maintaining a robust training platform that meets the demands of modern aviation.
