The KSAP-800 emergency escape system, developed for the UTS-800 basic flight trainer, has successfully passed a series of ground tests. This announcement was made by the press service of the aircraft’s developer, Ural Works of Civil Aviation (UWCA), also known as UZGA.

“During tests simulating various flight conditions, ejection trials were conducted using crash test dummies. The results confirmed that the KSAP-800 ensures safe pilot ejection throughout the entire altitude and airspeed range specified in the UTS-800’s operational parameters,” stated UWCA.

The KSAP-800 was developed jointly by UWCA and Zvezda Research and Production Enterprise. The system is designed to support both simultaneous and sequential pilot ejection. An integrated control unit allows the operating modes to be adapted to specific training missions. A mode selector for “simultaneous/sequential” ejection optimizes the sequence based on the number of crew members onboard.

The KSAP-800 includes ejection rails, mass-produced K-93 ejection seats, a control unit tailored specifically for the UTS-800, and an independent power supply. Using commercially available ejection seats helps reduce system costs and simplifies maintenance.

The K-93 ejection seat meets modern emergency escape system standards. A key feature is its “zero-zero” capability — the ability to safely eject at zero altitude and zero airspeed. This is a particularly challenging mode since the lack of airflow complicates parachute deployment. The K-93 propels the pilot to a sufficient altitude to ensure safe parachute opening and descent. This capability enables ejection even from a stationary aircraft, such as in the event of a ground fire.

The UTS-800 basic flight trainer is being developed in compliance with current aviation regulations and technical requirements provided by operators. The aircraft will support training in basic and advanced flight maneuvers at altitudes ranging from approximately 3,300 ft to 26,200 ft (1,000 m to 8,000 m).

The aircraft is designed to operate from both paved and unpaved runways. The UTS-800 is currently undergoing flight testing with the H80 engine produced by GE Aviation (General Electric). UWCA is also developing the VK-800SM engine, which will be installed on the LMS-901 Baikal regional aircraft and the UTS-800.
