  • Simulating horizontal stabilizer trimming in an aircraft
    Patent number: 5286203
    Abstract: The present invention features a simulator apparatus and method for realistically simulating actual forces at the horizontal stabilizer trim controls of an aircraft. The invention features a closed-loop, microprocessor-based programmable system with reduced mechanical, electromechanical, and/or hydraulic components. The microprocessor computes the required reaction forces using a softward model of the horizontal stabilizer trim system.
