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
