I think what's sometimes forgotten in all of this is that MACC in effect combines the function of two units, it performs a TMA function working a/c from departure (about 2500ft) all the way up to an AC function at FL285 and for descending a/c up to FL300+. It means all controllers combine both a TC and an AC function at the same time. That's where our complexity comes from. It's not just cruising trfc or climbing and descending TMA trfc...it's both at the same time sometimes on a 100 mile range. We don't want to belittle any other unit's...we just don't want them to do it to us.
