The height of the control tower is irrelevant to LVPs
Not entirely correct. As you quite rightly say, the implementation of LVPs is either at an RVR value OR a cloud ceiling, the key word being "or". Its very possible to have RVR readings in excess of 1500m, but cloud at about 150ft, hence LVPs based on Cloud and not RVR would be initiated.
I think the problems Mad Jock refers to arise if the tower is above 200ft tall, because by the book, you don't have to be in LVPs until the cloud ceiling drops to 200ft. If, however, your tower is, say, 250ft tall, you could be in the cloud, but LVPs wouldn't have to be initiated...by the book. I think that the MATS pt2 would be rewritten to increase the cloud ceiling values for LVP initiation prior to moving into a taller tower though, or it could be quite embarrassing!!!!
