  We review in some detail the QCD corrections to the measurement of the
forward-backward charge asymmetry of heavy quarks in the
$\mathrm{e^+e^-\rightarrow Q\overline{Q}(g)}$ process at the Z pole. We show
that the size of these corrections can be reduced by an order of magnitude by
using simple cuts on jet acollinearity. Such a reduction is expected to lead to
systematic uncertainties at the $\Delta \mathrm{A_{FB}^{0,Q}} \approx 10^{-4}$
level, opening up the path to high precision electroweak measurements with
heavy flavors at future high luminosity $\mathrm{e^+e^-}$ colliders like the
FCC-ee.
