High AoA flight poses unique aerodynamic challenges, and these issues are studied extensively over the years [1]. An air vehicle at high AoA allows the pilot to rapidly nose-point to ensures a decisive action on the enemy. That is why next-generation aircraft must be able to operate consistently at higher and higher AoA than before and in a controlled fashion, thereby posing newer challenges in control, especially with the possible deployment of SJAs. Freezing conditions can also promote a local high AoA flow condition where ice accumulation on the tail leading edge may have an equivalent effect of a full-span stall strip [2]. The trend in the next-generation air vehicle design is towards increased exploitation of high-AoA aerodynamics and flow-field interactions. The relevance of high AoA studies is widespread, contrary to the general understanding that the pilot of a light single-engine propeller-driven air vehicle may also encounter high AoA aerodynamics as frequently as the pilot of a modern high-performance fighter.
