Post-stall characteristics Supermaneuverability

the key difference between pure aerodynamic fighter , supermaneuverable 1 found in post-stall characteristics. stall, aforementioned, happens when flow of air on top of wing becomes separated due high angle of attack (this can caused low speed, direct cause based on direction of airflow contacting wing); airfoil loses main source of lift , not support aircraft until normal airflow restored on top of wing.

the behavior of aircraft in stall main difference can observed between aerodynamic maneuverability , supermaneuverability. in stall, traditional control surfaces, ailerons, have little or no ability change aircraft s attitude. aircraft designed stable , recoverable in such situation; aircraft pitch nose-down angle of attack of wings reduced match aircraft s current direction (known technically velocity vector), restoring normal airflow on wings , control surfaces , enabling controlled flight. however, aircraft deep stall; aircraft s design inhibit or prevent reduction in angle of attack restore airflow. f-16 has flaw, due in part fly-by-wire controls, under circumstances limit ability of pilot point nose of aircraft downward reduce angle of attack , recover. neither extreme pitch-down nor deep stall desirable in supermaneuverable aircraft.

a supermaneuverable aircraft allows pilot maintain @ least control when aircraft stalls, , regain full control quickly. achieved largely designing aircraft highly maneuverable, not deep stall (thus allowing quick recovery pilot) , recover predictably , favorably (ideally level flight; more realistically shallow nose-down attitude possible). design, features added allow pilot actively control aircraft while in stall, , retain or regain forward level flight in extremely shallow band of altitude surpasses capabilities of pure aerodynamic maneuvering.
