What are the three phases that a spin will progress through?

• A. Post-stall gyrations, progressive spin, steady state spin
• B. Post-stall gyrations, incipient spin, steady state spin
• C. Progressive spin, incipient spin, steady state spin
• D. Progressive spin, aggravated spin, steady state spin

Answer: (B)

The three phases that a spin progresses through are accurately represented in the option mentioning post-stall gyrations, incipient spin, and steady state spin. Initially, during post-stall gyrations, the aircraft begins to lose controllability, and uncoordinated inputs can lead to a loss of aerodynamic control. Following this phase is the incipient spin, during which the aircraft enters a defined spin. This phase is characterized by a developing rotation and the transition into a fully developed spin if the conditions remain unchanged. Finally, in the steady state spin phase, the aircraft maintains a consistent rotation rate about its vertical axis, and the aerodynamic forces have reached a stable balance. Understanding these phases is critical for pilots so they can recognize the signs of a spin and take appropriate corrective measures to recover from it.
