17 deg is typically the stall angle for a wing.

stall-hyst-norm, normally at 0 ('good condition'), switches to 1 ('bad condition') at 17 deg (alpha-deg or corresponding alpha-rad value, different from alpha-wing-rad if wing incidence is not zero).

Later on, it returns back to 0 only when alpha-deg comes down to 5 deg (that is with some 'delay'). Close to the usual hysteresis behavior (usually, iron magnetization vs magnetic field, with magnetic field h corresponding to alpha angle for us), but the delay is not dependent on the max value attained by the variable alpha. A kind of 'rectangular' hysteresis loop, more simple but already good for aerodynamics (linear or turbulent) regimes.
