ACS element text (the applicant demonstrates understanding of)

Range and limitations of stall warning indicators (e.g., aircraft buffet, stall horn, etc.).

Bottom line

Noise within the flight deck may mask the sound of the stall warning horn. Symptoms of an impending stall include a stall warning light or horn, airframe or elevator buffet, or a sudden loss of control effectiveness. During slow flight, any further increase in angle of attack, increase in load factor, or reduction in power will result in a stall warning.
