Equivalent Airspeed Calculator by Mohit Kudal

 

Where;  W = Weight of aircraft (N)

S = Wing Area (m^2)

ρ0 = Density at Sea level (kg/m^3)

CL = Lift coefficient

Equivalent Air Speed [EAS] defined as the velocity at sea level. Under the ISA conditions that would produce the same incompressible dynamic pressure as compare the dynamic pressure due to true airspeed .
