2. Customer Needs Instrument the existing throttle lever with position transducers Maintain control mechanisms such as pilot interface handles, range of motion and feel Instrument the existing rudder pedals with displacement and force transducers Maintain control mechanisms such as pilot interface pedals, range of motion and feel Instrument the existing yoke with displacement (axial and rotational) and force transducers Maintain control mechanisms such as pilot interface grips, range of motion and feel Enable feedback from all transducers (force, spring rate and drag)

3. Customer Needs (cont.) Install LCD monitor in front of each pilot station (2) Implement an emergency stop function in multiple locations that will allow a given simulation to reset if one operation fails Two wire (signal and return) cable Two emergency stop switches located at each pilot station Two switches made available for ground personnel Clear labeling of switch function Pull to operate, push to stop Install cabling from all transducers and monitors to the ground Interface connector for easy disconnect/replacement Rout cabling to ventilation tube and wire way conduit Provide a minimum of 10ft cabling beyond conduit exit Install mounting system for side stick inceptor. Design elbow and wrist assembly for pilot comfort

4. Engineering Specifications Rudder sensor must output a position signal from 0 to 5 V Throttle sensor must output a position signal from 0 to 5 V Yoke sensors must output a position and rotation signal from 0 to 5 V All controls provide X lbf feedback Monitors are mounted in cockpit (yes/no measurement) Emergency stop resets simulation (yes/no measurement) All cabling is able to reach computer system (yes/no measurement) Items in italics need to be determined

6. Pugh Matrix Weighting Ease of Maintenance How easy is it to get to the sensor if there is problems? Importance - Medium Accuracy How close does the sensor measure position? Importance - High Ease of Installation How easy is it to mount the sensor? Importance - High Durability How often will the sensor need to be replaced? Importance - Medium Cost How much does the sensor and associated signal conditioning cost? Importance - Low

7. Yoke Drawback – Sensor Type LVDT Type dependent on mounting location Most reliable, most expensive Encoder Similar in cost, still reliable Quadrature Output String Potentiometer Type dependent on mounting location Cheap, will wear out

8. Yoke Drawback – Mounting Location Connected to yoke shaft itself Most direct -> could be most accurate Complex geometry causes problems Attached to cable Simplest Least direct -> chance for cables to slip etc -> chance for lower accuracy

9. Yoke Drawback – Signal Conditioning LVDT Requires an expensive signal conditioning board to output 0 to 5V Board produced by Moog Analog board can be made Encoder Requires a less expensive signal conditioning board to output 0 to 5V String Potentiometer No conditioning necessary

10. Yoke Drawback – Pugh Matrix

11. Yoke Rotation – Sensor Type RVDT/LVDT Type dependent on mounting location Most reliable, most expensive Encoder Less expensive, still reliable Quadrature Output Rotational/String Potentiometer Type dependent on mounting location Cheap, will wear out

12. Yoke Rotation – Mounting Location On yoke itself Most direct -> could be most accurate Complex geometry causes problems On Pulley for cables Less direct -> slightly less accurate then on the yoke Easier to mount then on yoke Attached to cable Simplest Least direct -> chance for cables to slip etc -> chance for lower accuracy
