Let k be an algebraically closed field of characteristic p≠ 0. Let G be a connected reductive group over k, P ⊆ G be a parabolic subgroup and λ: P \longrightarrow G be a strictly anti-dominant character. Let C be a projective smooth curve over k with function field K=k(C) and F be a principal G-bundle on C. Then F/P \longrightarrow C is a flag bundle and Lλ=F ×P kλ on F/P is a relatively ample line bundle. We compute the height filtration and successive minima of the height function hLλ: X(K) \longrightarrow ℝ over the flag variety X=(F/P)K.
