1. Flight Test Engineering An introduction Into to Flight Test Engineering

2. Why Flight Test ? • Adequate replication on the ground of flight conditions is often impractical • Particular flight conditions may be insufficiently well defined to be simulated • Almost all aircraft incorporate many system whose interactions are complex • Discrepancies between actual flight behavior and predicted. Flight test data is essential to improve accuracy of the models and simulation. Flight Test is required to prove that the man/machine combination can achieve the desired “performance”. Into to Flight Test Engineering

3. Nature of Flight Test Expensive • Requires instrumentations, infrastructure, special maintenance of test vehicle, test area, specific weather conditions and qualified people. • Involving many parties. Inherently Hazardous • New configuration; unproven system; at the edge and beyond of flight envelope. • Explore the most critical configuration and failure cases of system. • Extensive preparation and careful planning. • Minimize flight hour • Crew readiness • Hazard assessment • Safety review Into to Flight Test Engineering

4. General Approach of Flight Testing Testing in operationally representative condition in a controlled, incremental manner with critical parameters monitored via appropriate instrumentation. • Starting from less hazardous and gradually towards more hazardous case • Comparison between test results and prediction • Explore aircraft envelope to ensure that aircraft meets requirements at the most critical conditions. • Testing in a known and controlled condition (suitable weather, low air traffic density, flight test instrumentation, safety equipments and dedicated test support) Into to Flight Test Engineering

5. Type of Flight Test • Experimental Flight Test • Research and Development purposes • Development and Certification Flight Test • Demonstration for the purpose of showing compliance with design objective and/or airworthiness requirement. • Must be performed using representative aircraft, proven instrumentation and test maneuver as per requirements. • Production Flight Test and Flight Test After Maintenance • Testing of series aircraft to ensure correct installation/maintenance within the established limitation Into to Flight Test Engineering
