In my humble opinion RVSM operations in the United States is a complete waste of money, time and materials.
There are traffic delays for operations at DFW on clear weather days, there are delays for ORD during marginal VFR days. On any given day in the United States there ground holds for many major airports.
The problem we in the US is not airspace, we have plenty of that. We don’t have enough runways.
Now can anyone explain to me how, by putting more aircraft in the sky between, say LAX and PHX that because of RVSM that will alleviate the S turns, 90 degree turns off course and just plain holding that existed before RVSM because of airport saturation?
Bottom line is that in the US ATC delays are because of airport saturation, not airspace saturation. You only fit so many airplanes on a runway and by have more airplanes in the sky wanting to use that same runway is not going to help.
Yes my airplanes are RVSM certified, and it wasn’t cheap. But we were RVSM certified for Europe anyway.
