Progress in Air Traffic Control and its Relationship to Airport and Aircraft Development

Extract

The theme of this symposium is “Inter-Relations and Inter-Face Problems.” It is suggested that what are called “inter-face problems” are sometimes no more than symptoms of a failure to get priorities right. There is, presumably, an “inter-face” between a dog and its kennel. But if the dog owner wants a kennel then he gets one of the right size. The dog takes priority and no inter-face problem arises. Similarly, if someone owns a car and wants a garage for it then he has one built to the appropriate dimensions. It is only if he already has a garage that cannot be enlarged and buys a car too big for it that he is confronted by an inter-face problem but there would have been no problem had he, in this case, given first priority to the garage and bought a car to fit it.
