Vs1g is best described as which speed for gust-load certification calculations?

Vs1g is the stall speed in a normal 1-g flight condition. In gust-load certification, engineers use this speed as the reference because near the stall the airplane has the least margin to maintain lift when a gust pushes the wing, so the gust loads are evaluated at the lowest safe speed in steady, level flight. Using Vs1g provides a conservative baseline, ensuring the structure is designed to withstand gusts even in the most critical, low-speed scenario. The other speeds relate to different flight phases—engine-out climb, final approach, and maximum operating speed—and aren’t used for gust-load calculations.
