Flatspin,
Air4ce is essentially correct, however it has kinda negative connotations. The Tower/Terminal B-stand is NOT an administrative asistant. Everyone in a tower and a terminal environment has their own job to do, with the common goal of moving metal in a safe, orderly and efficient manner.
Tower- various towers have from one to three Officer controllers on duty at a time, and may have a supervisor there as well if things are extremely busy. There will also be an NCM ground traffic ontroller, as well as an NCM supervisor for particularly busy times. The Data controller/data assistant/B-stand (same position, three names) will feed information to all positions, and imho is easily the busiest position in tower. A typical busy day in Cold Lake Tower will see a Tower controller on each runway (inner and outer) as well as a third controller streaming the flow into the control zone. There will be a ground controller as well as a data assist. Finally, there will be a senior controller watching over all, as well as a senior NCM helping the ground and data. On a good day, there will be app 100+ movements per hour, and each and every single one of them will go through the data dude twice. Miss one, and you may have left a guy for dead. As well, you'll have a zillion phone calls to work, info passed up from radar, co-ordinating calls from outside the unit, and emergencies (there always are) to announce on the base PA, as well as initial response to get going- you do all of that too. Again, I've done every position, lots, and imho the data assist is the busiest.
Terminal- no change, except now you'll be taking and issuing flight plans, and to do this you'll get to talk on a radio to pilots. Same number of movements, more controllers to babysit, and more responsibility- screw up a flight plan and I guarantee someone will be hurting. As well, on big recoveries you may well end up writing strips for the terminal controller. Again, I've done all the postions in Terminal and imho the data assist is the busiest person in the room.
Best of all, after you've proven yourself in data there's a PAR or ground course on the way. May only take one year, may take more....but it is usually very quick, we prefer people to be qualified in all positions.
Generally speaking, the ATC NCM's have more responsibility on their shoulders than anyone else I know of. For instance, a PAR controller will be 100% responsible for landing 50 Mil $ fighters all day long, on their own. As well, you'll do the same for 200 Mil $ 747's with 300 people on board....screw that one up, you'll have to serve 300 years to pay supply back
It's a good trade, though not for everyone. If you cannot handle stress or think fast on your feet, find another way to make a living. If you can, it's a great way to live.
Cheers-Garry
