Design and research of real-time monitoring software for IFTD flight test of civil aircraft

The IFTD (In-Flight Thrust Determination) flight test is an important step to measure the level of aircraft-engine integrated design. Due to the large number of IFTD flight test items and high test accuracy requirements, higher requirements are put forward for ground monitoring personnel in three aspects: judging the effectiveness of the test point, improving the completion efficiency of the single flight test point and ensuring the safety of the test flight. Based on the concept of intelligence, automation, customization and quantification, this paper studies the IFTD flight test process, and designs the IFTD flight test real-time monitoring software based on the .Net framework and the WPF (Windows Presentation Foundation) user interface framework, which has the functions of real-time monitoring of key parameters of the flight test, threshold reminder, real-time data recording and data playback. Realize the monitoring of aircraft flight status stability, realize the rapid judgment of the effectiveness of test items, and improve the efficiency of flight tests.
