300‑X vs. 400‑X Control Loaders
The 300‑X and 400‑X control loaders share Servos & Simulation’s core servo‑based control loading architecture but are engineered for different levels of simulator fidelity and certification requirements.
Model 400-x
The 400‑X, by contrast, is engineered for higher‑force, higher‑fidelity applications and is intended to support FAA Level D full‑flight simulator architectures.
Together, the 300‑X and 400‑X allow simulator developers to select the appropriate control loading solution based on certification level, force requirements, and system scale, while maintaining a consistent servo‑based design philosophy and long‑term supportability across programs.
Certification Support and System Design
The 300‑X is engineered to support FAA Level 1 through Level 7 training device applications and has been integrated into simulators for aircraft platforms such as CRJ, 737, A320, and Robinson R22/R44. Its modular electronics architecture and streamlined cabling design enable straightforward installation, simplified maintenance, and long‑term operational durability.
All major components are based on commercial off‑the‑shelf (COTS) hardware, with application‑specific adaptations implemented.
Flight Control Software Model
The software model is based on the flight model provided with centering springs if required.
The model is designed so that it can be tuned from the Host, thus it could be used for any light aircraft or transport.
Except for setting the scale factors for position and force, this model will not need to be tuned to each specific application.
Control Parameters from Host
Dynamic pressure, roll rate, pitch rate, yaw rate, dynamic pressure divided by velocity, boost oil pressure, autopilot command, autopilot engage, weight on nose wheel, nose wheel velocity, and nose wheel angle.
If required by contract, other parameters could be added.
Safety
The safety system in the control loader monitors the output to the DAC that drives the electronics. Monitoring the DAC allows the safety software to abort the system if the command to the electronics is excessive.
In addition to the analog variables monitored by the safety software, the enable command to the electronics has a one-shot that must be continuously re-triggered by the software. Should the software halt for any reason, the one-shot will time out and the loader will abort. E-Stop safety switches can be utilized for a mechanical abort.
Configuration Flexibility and System Compatibility
Model 300-X
The Model 300‑X is fully configurable to accommodate a wide range of torque and load requirements, allowing it to support multiple control configurations without extensive system redesign. This flexibility enables efficient adaptation across diverse training and simulation platforms.
When integrated with Servos & Simulation motion base platforms, the 300‑X forms part of a cohesive, unified simulation architecture supporting professional training and evaluation environments.
FAQ
The Model 300‑X is a servo-driven control loading system designed to provide realistic force feedback for simulator controls such as yokes, pedals, and throttles in professional simulation environments.
The Model 300‑X is typically used in FAA Level 1–7 simulation systems, training devices, and research applications requiring accurate control feel and repeatable performance.
The “X” indicates the number of control axes in the system. For example, an aircraft configuration typically uses 3 axes (pitch, roll, yaw), while additional axes can be added for throttle, nose wheel steering, or other controls.
The Model 300‑X provides dynamic, servo-driven force feedback that adjusts in real time based on simulation inputs, replicating the behavior of real-world control systems.
It integrates with host simulation software through control interfaces and communication systems, allowing real-time response to flight dynamics and control inputs.
Yes. The system can be configured for different numbers of axes, control types, and performance requirements depending on the application.
