\section{Summary and outlook}  The present study is only a first look at this topic for the FCC-ee. It enhances the fantastic potential of a 100-km circular ${\rm e^+e^-}$ collider already envisioned in Ref.~\cite{Bicer_2014} with the full profiling of the top quark from a precise measurement of its electroweak couplings. It becomes now of particular interest to check the added value of these measurements to the sensitivity to new physics, when combined with the unequalled precision of the measurements of the Z, the W, and the Higgs boson properties, as well as of the top-quark mass, at the FCC-ee.   Although the present projections were obtained with somewhat conservative hypotheses on the detector performance, it will also be important to reproduce these results with a Monte Carlo study, as to further investigate that the detector requirements are indeed quite modest. While the inferred precisions are already competitive with other projects on the market, this study will benefit from, for example, the energy and angular distrbutions of the b-quark jets and their correlations with the lepton distributions, to improve the precision on all couplings and in particular on $F_{1A}^Z$. Finally, the CP-violating form factors, ignored in this study for the sake of an easy comparison with Ref.~\cite{Baer_2013}, will have to be included too. Event variables, such as the asymmetry between the negative and the positive lepton distributions~\cite{Grzadkowski_2000}, will be interesting to study in this perspective.
