How does increased weight affect stall speeds?

In aviation, stall speed is defined as the minimum airspeed at which an aircraft can maintain level flight. When the weight of an aircraft increases, several aerodynamic principles come into play that directly impact stall speed.

As the weight of an aircraft increases, it requires a higher angle of attack to generate enough lift to counteract the increased weight. This higher angle of attack leads to an increase in stall speed. Essentially, as weight increases, the lift required to maintain level flight also increases, which necessitates flying at a higher speed to achieve that lift without reaching the critical angle of attack.

Thus, it is accurate to say that increased weight raises stall speed, making it crucial for pilots to be aware of their aircraft's weight and how it affects performance during various phases of flight, particularly during takeoff and landing. Understanding these dynamics helps ensure safe and effective flight operations.
