Final answer:
The different V speeds are indicated on the airspeed indicator within an aircraft's cockpit using color-coded markings and notches. These speeds correlate with critical phases such as takeoff and landing, as well as safety limits for aircraft operation.
Step-by-step explanation:
The different V speeds are depicted on the airspeed indicator in an aircraft's cockpit. These speeds are critical indicators of certain performance benchmarks in the aircraft's flight envelope, such as takeoff, landing, and structural integrity speed limits. The airspeed indicator is calibrated with various color-coded markings and notches which correspond to these speeds.
For instance, V1 is the takeoff decision speed beyond which the takeoff must no longer be aborted. VR, or rotation speed, is the speed at which the pilot begins to apply control inputs to raise the nose off the runway during takeoff. VSO represents the stalling speed in a specified configuration (such as with landing flaps and gear extended), and VNE is the never exceed speed, beyond which the aircraft's structural integrity cannot be guaranteed.
