honest to gosh, it seems like some "BACK TO BASICS" airmanship work is needed.
first, read: "STick and Rudder" and look at the stuff on spot landings, stall down landings and so forth.
tells you how to aim...now I'm not saying you should really full stall a jet transport on landing, but you can reduce speed, blending the flare so you touchdown on or near your spot at the target airspeed (maybe ref minus five?).
