Change in force along the longitudinal axis calculator

Various factors including velocity changes and drag coefficients. This force is typically related to the aircraft’s acceleration or deceleration

• Xu​ is the change in force along the longitudinal axis.
• $Q$ is the dynamic pressure (in pascals).
• $s$ is the reference area of the aircraft.
• $m$ is the mass of the aircraft.
• 0u0​ is the equilibrium velocity.
• CDu​ is the coefficient of drag with respect to changes in velocity $u$.
• Cd​ is the coefficient of drag at the equilibrium velocity 0u=u0​.
