ACS element text (the applicant demonstrates understanding of)

Enter a stall in a specified configuration and exceed the critical angle of attach a second time during the recovery.

Bottom line

Abrupt pull ups at high diving speeds may produce recurrent or secondary stalls by increasing the AOA to that of stalling. Load factors induced during the pull up following stall recovery may be further increased inadvertently during excessive diving and abrupt pull ups to level flight. The most important stall recovery step is to reduce the angle of attack (AOA).
