Vertical force component (net force acting vertically on the aircraft) calculator)

The vertical force component in flight mechanics, also known as the “net vertical force,” refers to the resultant force acting in the vertical direction on an aircraft. It’s the difference between the lift force and the weight force. The vertical force component is a key factor in determining the aircraft’s vertical equilibrium and its behavior in the vertical dimension.

• $\rho$ is the air density at the aircraft’s current altitude.
• $u$ is the airspeed or velocity of the aircraft relative to the surrounding air.
• $S$ represents the reference area, often the wing area, of the aircraft.
• $CL$ is a coefficient associated with the aircraft’s lift or aerodynamic properties.
• $\Delta u$ represents a change in airspeed or velocity.
