1. SYSTEMS ENGINEERING APPROACH TO SYSTEM REALISATION P. Srikumar

2. LITERATURE ON THE SUBJECT LECTURES ON THE SUBJECT IMPLEMENTATION TOOLS EXAMPLES OUR PRACTICAL PROBLEMS IDENTIFY YOUR SYSTEM / SUBSYSTEM SE - THE STARTING POINT

3. CONCEPT OF OPERATION Eg: Long Range / Endurance UAV REQUIREMENT FOR THE MISSION PLAN THE MISSION PREPARE SYSTEM TEST SYSTEM LAUNCH / TAKE OFF CRUISE – NAVIGATE, ALTERNATE MISSION LOITER IN AREA INTEREST FOR RECCY / SURVEILLANCE TRANSMIT INFORMATION RETURN CRUISE LAND BACK & REFURBISH

4. ALLOCATION OF FUNCTIONS TO SYSTEMS 1.GROUND CONTROL STATION a)MISSION PLANNING & CHECKOUT SYSTEM b)MISSION MONITORING & CONTROL SYSTEM 2.LAUNCHER / RUNWAY 3.AIR VEHICLE 4.PAYLOAD 5.COMMAND & DATA LINK FUNCTIONAL REQUIREMENTS

5. PERFORMANCE REQUIREMENTS 1.OPERATIONAL SPEED 2.MIN & MAX SPEED 3.ALTITUDE OF OPERATION 4.RANGE / RADIUS OF ACTION 5.ENDURANCE / MISSION TIME 6.PAYLOAD OPERATIONAL REQUIREMENTS

6. SYSTEM REQUIREMENTS COMPLETE UNDERSTANDING & APPRECIATION OF 1.OPERATIONAL REQUIREMENTS VERIFIABLE a)STORAGE, HANDLING b)PREPARATION, TESTING, DEPLOYMENT c)OPERATIONAL FLEXIBILITY, RELIABILITY 2.PERFORMANCE REQUIREMENTS MEASURABLE a)ACCURACY, RANGE, ENDURANCE b)SPEED, ALTITUDE c)FUEL, PAYLOAD

7. CAPABILITY ANALYSIS TO ESTABLISH MATURITY OF 1.EXPERTISE 2.TECHNOLOGIES 3.ENGINEERING 4.INFRASTRUCTURE 5.FUNDS 6.VIABILITY CAPABILITY TO DEVELOP A VIABLE & USEFUL SYSTEM IN TIME & WITHIN REASONABLE COST “TECHNOLOGY READINESS LEVEL”
