Performance Centered Navigation (PBN) - Why the "Deborah" Should Be an "E"
In aviation we be seemingly creating abbreviations at an interest rate that increases the specter of our grandchildren lacking any practical combinations remaining any more. This comment from the effectively respectable colleague of mine who used to work for UPS airlines does actually indicate a couple of problems that exceed the scarcity of available special page mixtures and which, as we will have, affect our everyday perform in all sorts of unexpected ways.
Think about the well-known CNS development which, all of us know, represents Communications, Navigation and Surveillance. Whoever created the abbreviation CNS probably had no strategy simply how much damage their innovation could trigger in air traffic management by perpetuating the sort of silo thinking that maintains several businesses hopelessly separated and some professionals retreating to their respective ivory towers.
If at the very least the inventors had the nice sense of getting those letters in to some kind of logical buy, like record, which will have provided us NCS... We did steer first (as in trying to find our way by examining the titles of prepare stations and traveling along highways), then conveyed, initially with lights and hand signs and later via radio and most recently we do detective also. Not that NCS would have been any benefit at operating the silo attitude from the face area of the earth.
Of course in the old days there is some reasoning in considering moving and communicating as something many different from each other. You experienced for just
one or another, airplane carried split navigators and radio operators and when radar got along, the wizards of that equipment were a new type yet again. It was only reasonable also that separate fiefdoms must develop across the words NCS with hardly any outside contact between them. That they need to fiercely defend their particular domains was completely natural...Let us now jump ahead several decades to reach in our own courageous occasions wherever CNS still rules, the fiefdoms are mostly there still... OK, so where is the issue? The problem is, while the CNS organization kept mostly exactly the same, the entire world about it has fully changed. Looking at air traffic management along a CNS organization is like holding the TGV (High Pace Train) behind a water locomotive and wondering why there's therefore significantly smoke with the train just moving along.
Search at GPS. This clever process does just a few things: it offers you accurate time and signs from which you can assess a situation fix. What letter of the miraculous trio would you spend compared to that? We broadcast augmentation signals to the plane to help make the GPS position repair a lot more accurate, using a VHF digital link... Is that D or Deborah or S??? Ultimately, the airplane may broadcast its GPS produced position for different plane and the bottom to use in several ways. Well, at least that is obvious, we are speaing frankly about S for detective, right? Partially sure but a position may be, and will be, employed for a great many other purposes that fall way outside the original definition of surveillance.
Our world has developed right into a knowledge based enterprise and air traffic administration is not any exception. In the GPS case, generally the same knowledge is being applied and re-used and it's the end-user applications that determine whether it ends up being part of navigation or surveillance... or communications for that matter. The air traffic administration earth isn't about communications, navigation and surveillance. It is about knowledge which can be any of the popular C or D or S without the necessity, or certainly the possibility, to erect silos around it.
