: For aircraft with pressurized cabins, the skin must resist the internal pressure differential to prevent collapse or fatigue.

: These include maneuver loads (e.g., pull-ups or turns), gust loads from atmospheric turbulence, and loads from control surface deflections. Aircraft Loading and Structural Layout (Aerospa...

Before structural analysis begins, all external and internal loads must be identified. These loads are generally categorized by the aircraft's operating phase: : For aircraft with pressurized cabins, the skin

: Encountered during taxiing, landing, towing, and braking. Landing typically generates significant vertical load factors and shock loads on the gear. : For aircraft with pressurized cabins

The structural layout defines the "load paths"—the routes through which forces travel from their source (like wings or engines) to be balanced elsewhere. 1 Aircraft Structural Components and Loads
