Stall velocity, often denoted as (Vstall), is the minimum speed at which an aircraft can maintain straight and level flight. It is the speed at which the angle of attack becomes so high that the airflow over the wings becomes turbulent, leading to a loss of lift and an aerodynamic stall. Pilots need to be aware of and operate above this speed to maintain control and prevent a stall. The formula to Calculate Stall Velocity as follows:
Where:
- Vstall is the Stall velocity in m/s.
- VT is the Touchdown velocity in m/s.
