The stall speed of an airplane is influenced by several factors, including weight, configuration, and aerodynamics. For a general understanding, the stall speed can be estimated using the formula that takes into account the aircraft's weight and its wing loading.

The stall speed increases as the weight of the aircraft increases because a heavier aircraft requires a higher angle of attack to maintain level flight, which in turn increases the speed at which the wings can no longer generate lift. For typical light aircraft, stall speeds commonly range between 50 to 70 knots for a low-weight configuration, but this can increase significantly with added weight.

Given the information that the airplane weighs 2,750 pounds, a stall speed of 91 knots aligns well with the principles of aerodynamic performance in relation to weight. This figure corresponds to normal performance ranges for various aircraft in this weight class, suggesting that configurations, such as wing shape and design, are optimized for lift and handling at this speed.

Thus, while stall speeds may vary based on specific design and load configurations, the selection of 91 knots reflects an accurate estimate for an aircraft of this weight under normal flying conditions.
