Altitude effect on Velocity Calculator

The altitude effect on velocity refers to the influence of altitude on the true airspeed (TAS) of an aircraft. As an aircraft ascends to higher altitudes, the density of the air decreases, leading to changes in aerodynamic performance and velocity. This effect is primarily attributed to the reduction in air density, which affects the aerodynamic forces acting on the aircraft. The formula to calculate velocity at an altitude (V=V_TAS) as follows:

Where:

• $V$ is the velocity at the given altitude (True airspeed V_TAS ) in m/s,
• V₀​ is the velocity at sea level (Indicated airspeed V _IAS) in m/s,
• $\rho$ is the air density at the given altitude (kg/m₃)
• ρ_0​ is the air density at sea level (kg/m₃)
