FAR 23.2215 — Flight Load Conditions

FAR 23.2215 is part of the airworthiness standards for normal category airplanes. It tells the applicant (the manufacturer seeking certification) which flight conditions they must analyze when calculating the structural design loads the airframe has to withstand.

The regulation requires design loads to be determined from three categories of flight conditions:

• Atmospheric gusts — the magnitude and gradient of the gusts used in the analysis must be based on measured gust statistics, not arbitrary values.
• Symmetric and asymmetric maneuvers — pull-ups, pushovers, rolls, yaws, and other maneuvers that load the airframe evenly or unevenly.
• Asymmetric thrust resulting from the failure of a powerplant unit (engine failure on a multiengine airplane).

Why it matters operationally: when you fly within the airplane's published limits (V-speeds, load factors, etc.), you're operating inside an envelope the manufacturer proved against real-world turbulence, maneuvering, and engine-out yaw loads. Exceeding those limits can take the structure beyond its certified strength.
