Problem
Our sponsor, CAVS, primarily researches problems with vehicles and human factors relating to vehicular systems
CAVS does not currently have a device to perform aviation research
CAVS wants to convert a cockpit familiarization trainer into a working, realistic simulator
![Page 5: Final Presentation Senior Design November 30, 2010.](https://reader034.fdocuments.us/reader034/viewer/2022051316/5697bfdf1a28abf838cb2aee/html5/thumbnails/5.jpg)
Solution
Design gauges and throttle to integrate with the current hardware of the cockpit.
Use data fromMicrosoft FlightSimulator to drive the instruments

Technical ConstraintsName Description
Gauges The device must implement five flight gauges for display (airspeed, fuel quantity, climb, compass, and altimeter).
System Response The device must appear to be real-time and have a delay of < 20 ms.
Voltage The device must be wall-powered.
Interface The device must interface with Microsoft Flight Simulator.
Input The device must implement a dual-engine throttle control with flaps.
