Excellent post Arfor.
For the pilots out there reading this- Dick constantly tells a lie, over and over, about controllers being "distracted" or some such rubbish, if they have to do more than one task or provide different services simultaneously. See his posts above. He claims it is a key reason for having E instead of C. He goes on to assert that ATCs elsewhere think it is a joke that ATCs in oz would do this.
ATCs in oz do this already (and have done for many years) because they have to (resources). It is not dangerous, the controllers don't get "distracted" or any such BS- often, controllers in oz will simultaneously provide FS (DTI), radar control in various classes of airspace, and procedural control- all simultaneously. A tower controller (with the correct workload), can do many things without becoming dangerously "distracted". Dick's lie that this cannot/shouldn't be done is just ignorant/mischievous. It's true, US controllers find it interesting, and they certainly wouldn't do it themselves over there- because they have ****eloads more traffic, and ****eloads more controllers to deal with that traffic (and FS etc etc). They don't do it over there- not because they think it's dangerous- they just don't need to. They have the resources. Much like the policeman on Norfolk Isl is the customs officer, the post master (and a number of other delegations) being told he can't do that because Dick asked the post master in New York if he thought he could run the customs at JFK as well as the DMV etc. and he laughed and said it wasn't possible.
In short, the only person persisting with this untruth is not an air traffic controller.
