  Flag matroids are a rich family of Coxeter matroids that can be characterized
using pairs of matroids that form a quotient. We consider a class of matroids
called positroids, introduced by Postnikov, and utilize their combinatorial
representations to explore characterizations of flag positroids.
  Given a uniform positroid, we give a purely combinatorial characterization of
a family of positroids that form quotients with it. We state this in terms of
their associated decorated permutations. In proving our characterization we
also fully describe the circuits of this family.
