I can only speak from personal experience of the Oz system; it fundamentally changes the way you do the job. You stop looking at strips and look almost excusively at the data blocks on the a/c. It has some plusses, but a lot of negs. Redirecting your attention to the scope sounds good, however you become almost totally reactionary as little planning can be done on e strips. At first, you write everything down, then input data to catch up. This could lead to huge workload issues. 'Feeding the elephant'. After about a month live you get comfortable not writing anything down, inputting straight to data. It actually is faster and better- AS LONG AS EVERYTHING IS ON THE RAILS. As soon as anything unusual happens, you are in big trouble. The system, like all computers, is very inflexible. If you have to create a plan on-the-fly, the number of mandatory data fields channels your att- not good in atc. You basically have to call for immediate assistance, no grabbing a blank and scribbling details. Similar with rerouting, depending on what tools they give you. Either way, formerly a simple matter, rerouting takes concentration.
I could go on for ages, but I'll let others more eloquent.
The majority of our assistants were sacked.
