AI/ML Based Flight Test Instrumentation
Wg Cdr RR Senthil Kumar, Indian Air Force, delivered a talk during the SFTE-EC Symposium 2022.He had undertaken a project based on AI/ML application for Flight Test Data Acquisition. The […]
Spin Testing for Trainer Aircraft
Modern aircraft tend to be more reluctant to spin compared to older designs, however it is not impossible for them to spin. Mishandling the controls in turns, stalls, and flight […]
Tutorial: Aircraft Inertial Navigation System Testing
Theory Airborne Inertial Navigation Systems (INS) are dead reckoning systems that measure the accelerations of the aircraft relative to the inertial space. Because of this frame of reference, the accelerations […]

Aircraft Manoeuvrability: Flight Testing for Manoeuvre Performance
Tutorial: Aircraft Manoeuvrability (PART-2: Introduction to the Limits)
Every aircraft’s operational manoeuvrability is limited by several fixed and variable factors. Typical V-n diagram The aircraft limitations shown on the V-n diagram are: 1. The lift boundary limitation. The […]
Tutorial: Aircraft Manoeuvrability (PART-1: Turn Performance)
The capacity to change the velocity vector is called manoeuvrability. Quantifying the manoeuvrability of an airplane involves documenting the acceleration, deceleration, and turning characteristics.
Stall Flight Testing
Flying Qualities Specifications defines good high angle of attack characteristics in terms that are qualitative rather than quantitative. The airplane must exhibit adequate stall warning, and in addition the stall […]
Stall AoA Limiter System Validation on Digital Combat Simulator (DCS)- F-16C Viper
F-16 C aircraft Flight Control System (FLCS) limits the AoA to 25 deg and 18 deg for Store Configuration-1 and 3 respectively. The Virtual Flight Test Centre undertook a test […]
