Demand Management is a bag of tricks intended to reduce the number of operations at an airfield. RAPC listed the following ideas. RAPC also predicted the reduction in the number of operations due to these techniques. As always, RAPC is not particularly credible but let's use their numbers to see what would happen.

The total reduction would be 19.3 per cent if all these techniques were implemented. The impact of doing this on the arrival rate is shown below.

Now there is only one peak above the SOIA minimum acceptance rate. That peak, at 9 AM, is three planes over the minumum SOIA rate. It would be easy to move those planes into a slot before or after the peak hour. Clearly Demand Management is something that will greatly reduce delays at SFIA. And they could implement it before they could build runways. The Bay Area has a fair amount of power in Washington. Why aren't they lobbying our representatives to force the changes that would fix the problem?

RAPC left out at least one technology that is being implemented and expected, by the FAA, to be in-place within three to five years: AVOSS. AVOSS would increase the arrival acceptance rate. Want to see what that does?
