AVIATION & AERONAUTIC CALCULATOR
V Speeds
A precise tool.
What is the V Speeds & How does it work?
V speeds are critical airspeeds that define the operational envelope of an aircraft. These speeds ensure safe and efficient flight operations.
Vs = sqrt{frac{2W}{rho S C_{D0}}}
Vs = Stalling Speed, W = Weight, rho = Air Density, S = Wing Area, C_{D0} = Zero-Lift Drag Coefficient
Vno is the maximum structural cruising speed. It is the speed above which buffet may occur and below which the aircraft can be safely operated in gusty conditions.

Frequently Asked Questions
What is Vs in aviation?
Vs is the stalling speed of an aircraft, calculated using its weight, air density, wing area, and zero-lift drag coefficient.
How do I calculate Vno for my aircraft?
Vno is the maximum structural cruising speed where buffet may occur. It depends on the aircraft’s design and operational limits.
What factors affect an aircraft’s stalling speed (Vs)?
An aircraft’s stalling speed is affected by its weight, air density, wing area, and zero-lift drag coefficient.
Is Vno the same as Vs?
No, Vno is the maximum structural cruising speed where buffet may occur, while Vs is the stalling speed of the aircraft.
What should I consider when operating an aircraft at Vno?
When operating at Vno, be cautious of gusty conditions as the aircraft can still experience buffet below this speed.
