  We discuss prospects of studying supersymmetric model at future $pp$ circular
collider (FCC) with its centre-of-mass energy of $\sim 100\ {\rm TeV}$. We pay
particular attention to the model in which Wino is lighter than other
supersymmetric particles and all the gauginos are within the kinematical reach
of the FCC, which is the case in a large class of so-called pure gravity
mediation model based on anomaly mediated supersymmetry breaking. In such a
class of model, charged Wino becomes long-lived with its decay length of $\sim
6\ {\rm cm}$, and the charged Wino tracks may be identified in particular by
the inner pixel detector; the charged Wino tracks can be used not only for the
discrimination of standard model backgrounds but also for the event
reconstructions. We show that precise determinations of the Bino, Wino, and
gluino masses are possible at the FCC. For such measurements, information about
the charged Wino tracks, including the one about the velocity of the charged
Wino using the time of the hit at the pixel detector, is crucial. With the
measurements of the gaugino masses in the pure gravity mediation model, we have
an access to more fundamental parameters like the gravitino mass.
