Definition
A section of Title 14 of the Code of Federal Regulations, Part 23 (Airworthiness Standards: Normal Category Airplanes), that establishes the stall, stall warning, and spin requirements an airplane must meet to be certificated. It defines what spin behavior the airplane must demonstrate based on its certification category, including recovery characteristics and, for certain categories, resistance to spinning.
Plain English
This is the federal rule that sets the spin and stall standards an airplane has to pass to be approved by the FAA. It tells the manufacturer what the airplane must do (or must not do) when it stalls or spins.
Context Anchor
Seen in discussions of intentional spins, airplane certification, and whether a specific airplane is approved for spin training.
Derivation
CFR stands for Code of Federal Regulations, the published collection of U.S. government rules. '14 CFR' is the aviation volume. 'Part 23' covers small airplane airworthiness. The section number 23.2150 points to the specific rule on stalls and spins. Knowing the structure helps you find related rules quickly.
Why Pilots Care
Tells the pilot whether the airplane is certified to perform intentional spins and what recovery performance is legally required, directly affecting training and safety decisions.
Intuition Check
Do not read this as an instruction for how to perform a spin. It is a rule citation that identifies the certification standard the airplane was evaluated under.
Example Sentence 1
Before performing intentional spins, the instructor confirmed the training airplane met the spin recovery requirements of 14 CFR part 23, section 23.2150.
Example Sentence 2
Because the airplane was certified under 14 CFR part 23, section 23.2150, the pilot knows recovery must occur within one turn after applying opposite rudder and forward stick.
