Intermediate Jet Trainer (IJT) already has missed its Initial Operational Clearance (IOC) set for last year, HAL’s Director Design is hopeful that IJT will get its IOC this year. IJT for last few years has been facing issues with spin and stall of the aircraft which is considered too risky for newbie pilot to execute and recover while, in training.
HAL in past had carried out various realignment to wings and dead weight shifting ,Anti-Spin strips on its nose cone section for better recovery too were added but still issues remained and later BAE Systems, was roped in to provide consultancy to sort out some of the issues with the Intermediate jet trainer (IJT).
BAE Systems, after carrying out assessment in its recommended had suggested that aircraft’s tail will have to be redesigned to address serious stall and spin issues. Questions now remains is whether HAL claims of a modification been carried out will resolve stall and spin issues, which are important aspects in trainings of new pilots.
