The polar is obtained by repeating this calculation over the entire range of lift coefficients (i.e. airspeed), whereby the effects of Reynolds number variations must also be taken into account.
The airspeed polars corresponding to a given gross weight are determined using:
It is also interesting to compare the relative magnitudes of the individual drag contributions at different airspeeds.
Considerable airspeed variation is observed.
At low airspeed (high CL), the induced drag contributes over 50% of the total drag.
