As a leader in horizontal stabilizer trim actuation, Safran equips many civil and military programs. Our HSTA systems enable to keep the aircraft’s attitude stable, by minimizing aerodynamic forces and reducing drag.
High performance and reliability for a safer flight
Balance of aerodynamic forces for a stable flight attitude
Reduction of the pilot workload and fuel consumption to fly more efficiently
During the all flight, the HSTA controls the pitch of the aircraft, while minimizing the pilot workload and fuel consumption, to fly more efficiently. According to the weight, pressures and center of gravity of the plane, the flight control computer sends order to the HSTA via its electronic control unit to adjust the angular positioning of the horizontal stab.
Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
