The Federal Aviation Administration Has Been Struggling for Several Years

The Federal Aviation Administration has been struggling for several years with antiquated systems,and all it takes is a single failure on one piece of the system to shut down the entire air-traffic control system for several hours,resulting in significant snarls at major airports.The most recent failure occurred in the FAA's core telecommunications network,called the Federal Telecommunications Infrastructure (FTI) ,which is managed by Harris Corporation.Marc Raimondi,a spokesperson for Harris Corporation,said,"The FTI system has proven to be one of the most reliable and secure communications networks operating within the civilian government." Snafus like this have been happening with alarming frequency,prompting Congress to demand the FAA and its contractors to do more to prevent these malfunctions.The problem is that the FAA has been using a patchwork approach by updating with modern hardware and software on old systems instead of a complete overhaul of the system.The FAA's next generation of modernization will rely on satellite-based networks instead of phone lines and data cables.The FAA is waiting for White House approval on whether it will have the funds to take this next step.
-Refer to Federal Aviation Administration.When the FAA purchases a satellite-based system,this will be a situation in which it is purchasing an entire system,not just a modified part or new vendor for existing parts.Basically,this is a situation in which the FAA will be purchasing a system for the first time and is referred to as a(n) :

A) straight rebuy
B) modified rebuy
C) new buy
D) original equipment purchase
E) primary purchase
