What does "Vso" refer to in the Warrior PA-28A?

"Vso" is a critical aerodynamic parameter for the Warrior PA-28A and refers specifically to the stall speed in landing configuration. This is the minimum airspeed at which the aircraft can be flown with the landing gear extended and the flaps in the landing position, just before it reaches a stall. Understanding Vso is vital for pilots, especially during approach and landing phases, as it helps ensure safe operations at slower speeds. It is essential for determining safe maneuvering speeds and managing the aircraft within its performance limitations. Therefore, knowing the Vso allows pilots to maintain control and avoid stalling during these critical phases of flight.
