(Cranford is at the
EASTERN end of 09L/27R)
The runway alternation is not really noise limitation, rather more like noise management. Westerly operations alternate to give the folks of Cranford and other local environs a degree of respite during at least some of the time by ensuring that arrivals use the southern runway for half the day when on westerly ops.
I would be interested though to see comparative studies of sound levels produced by the air traffic of today compared to that in the past.
While the instantial sound level of each movement must surely have reduced, the frequency has certainly increased vastly. At what point would a reduced noise level be balanced by the increased frequency of events?
Maybe this kind of research might support a relaxation of the Cranford Agreement (which dates back to 1952 remember
) for some kinds of operational techniques; short-hauls allowable departing from 09L for example.
