I've got one. Get rid of the useless non-radar E airspace band between 185 and 245. It prevents IFR aircraft from using block levels, thereby wasting fuel, discomforting passengers and preventing crews from easily finding smooth air to operate at the most economical speeds, all because of the VERY FEW Australian-registered VFR aircraft that are legally permitted to fly above FL200 and whose pilots are selfish enough to want to put themselves ahead of thousands of other airspace users.
probably designed for 747s, but hardly necessary for the Piper Cubs and Cherokees
There you go, living in your own vacuum again. Have you ever thought of the poor 737 crew trying to spot a bugsmasher joining a 1nm oblique final under their nose? I didn't think so. If you want to remove the rule for your paddock, then that's fine. Just make sure that's all that's changed. Aviation is getting dangerous enough without a free-for-all in the CCT.
