The Horsforth end of the runway is more or less flat, but there is then the downslope that is visible in Aviadors photo. The main problem with that is that landing aircraft sometimes tend to drift down the runway when landing on 32, because as they drop down towards the runway, the runway drops down too, resulting in aircraft sometimes taking a little longer to touch down, and so using up valuable runway length. This is even more of an issue if its wet, still more of a problem if its wet with a cross wind, and worse still if the aircraft is large or not particularly brilliant at braking (eg the A321).
Otherwise, I am not sure it makes much difference. One day hopefully, the touch down point can be moved back to where it used to be, nearer the Horsforth end, where there is no downslope. Sadly, as others have already posted on here, its not that straightforward and again very expensive. Perhaps if the airport increased the drop off zone fee to £5 they might afford to do it one day!! 😉
