What is the significance of the "V" speeds in aviation?

The "V" speeds in aviation represent reference speeds that are essential for safe flight operations. These speeds are critical for pilots to understand and utilize during various phases of flight to ensure the aircraft is operated within its safe operational limits. For instance, V1 is the decision speed during takeoff; V2 is the takeoff safety speed; and VS is the stall speed, among others.

Understanding these speeds helps pilots make informed decisions regarding the aircraft's handling characteristics, takeoff and landing performance, and safety margins during flight maneuvers. Each "V" speed serves a specific purpose based on the aircraft's operating envelope and provides critical information regarding performance thresholds.

In contrast, the other options do not capture the essence of what "V" speeds signify. Fuel consumption rates, baggage weight limits, and minimum altitudes are important aspects of flight operations but are not represented by "V" speeds.
