The Different Types of V-Speeds for Small Aircraft
When flying an aircraft, it is important that you take into account the speeds at which you are traveling for safety and efficiency. In many instances, aircraft will need to be within a certain range of speeds to optimally carry out specific maneuvers, and to make things easier, airspeeds are often broken up into what are known as “v-speeds.” These v-speeds account for varying ranges of speed, and having a general understanding of the types and what maneuvers are carried out within them can help you better fly.
The first v-speed is the Vso speed, and it is known as the stall speed in the landing configuration. On an
airspeed indicator, Vso is denoted by the bottom of the white arc, and it is the stalling speed when an aircraft is in its landing configuration.
The next v-speed is Vs, and it is the stall speed in the clean configuration. This speed range is marked by the bottom of the airspeed indicator green arc. The final v-speed that covers stalling speeds is Vs1, and it is the stalling speed obtained in a specific configuration, such as while operating with a maximum takeoff weight while in a clean configuration.
With Vr v-speeds, one achieves the rotation speed at which the pilot makes a control input. Often, this range is traveled while trying to lift the airplane up from a runway surface or water. At the Vx v-speed, the aircraft enters the best angle-of-climb speed which ensures that the highest gain of altitude is obtained for a given horizontal distance.
This v-speed is regularly used during short-field takeoffs. The Vy v-speed is the best rate-of-climb speed and should not be confused with the Vx speed. Vy v-speeds are generally utilized during the post-takeoff climb or departure phase.
To reach the best glide speed, one will enter the Vbg or Vg v-speed. This range allows for an aircraft to have the most lift while facing the least amount of drag. For the maximum flap extended speed, one will want to remain within the Vfe v-speed range which is the top of the airspeed indicator white arc. To avoid damage to the flaps, one should ensure that they do not exceed this range.
The final three common v-speeds are Va, Vno, and Vne, those of which account for the design maneuvering speed, maximum structural cruising speed, and never exceed speed respectively. The design maneuvering speed is not usually marked on an airspeed indicator, though it is the maximum speed
aircraft manufacturers account for to avoid structural damage.
With the Vno v-speed, one can be aware of the speed they should not exceed unless in smooth, non-turbulent air while exercising caution. The Vne speed can be considered the most important, as it is the red line on an indicator that represents the speeds the aircraft should never exceed as it will cause structural failure.
As
v-speeds ensure safe flight, it is important that your aircraft gauges or glass cockpit components are all functioning properly before any flight.
