Longitudinal Trim Actuator

The Longitudinal Trim Actuator is a linear electro-mechanical actuator, providing linear motion during both extension and retraction, against a tensile or compressive load and consisting basically of an electric motor, including its control logic, and a reduction gearing that transforms the rotation movement into linear motion of the actuator rod.
The LoTA moves the A/C stabilizer surface to obtain aircraft trimming according to command provided by the Longitudinal Trim Switches on the Pilot stick grips.
Main features are:
– power supply 28 Vdc
– nominal speed 2.6 mm/s
– external load 3000 N
