I don't know about any visual clues, but if there's an ILS, flying a dot high should do it.
No ILS, you'll have to do the mental math and stay above the 3deg slope, or start off flying a 3 deg approach (descent = 5x GroundSpeed) with threshold as the aim point, then adjust to a slightly higher profile, say 4x gs).
That depends on how "big" the big airplane is
A turbo prop is big compared to a light plane, but the turbo prop might also be flying a higher than normal profile if they are following a heavy jet !
