Things do get a bit breezy on the "Rock", however if one keeps a firm hand on the throttle's {Thrust levers to the collage grads!} and get rid of auto throttles all will be well, the only aircraft I have had any problem holding the glide path when IMC was the Viscount when fully loaded, but it never got to the point of having to overshoot, its a great place for spending a layover and the population are the friendliest and most welcoming in the world!
