The human ear would not notice the accumulative noise differential between the MD11 and the B777. I could understand BRU’s position if DHL operated classic B747’s, however this is not the case. The capital acquisition costs of 5 B777’s would be approx US$1 billion. Should DHL be expected to pay this money to satisfy the airports requests, or are the locals willing to have their taxes increased in order to allow the government to buy the aircraft for DHL.
I remember that BRU invested a lot of money into the airport infrastructure to attract DHL as they wanted the jobs. Now if looks as if they will be extremely happy to lose them.
