FAA Reduces MSP Operations per hour

As you know, SMAAC has been advocating for a maximum MSP operations hour of 120 to 130, for three reasons: lower costs, less safety risk, and some noise and pollution reduction.

The major airlines are or will be asking for adjustments.The FAA is looking for ways to increase the MSP arrival rate (such as the A/D Window development or creative runway use). This might be unneeded if some hub (connecting) flights were moved to airports with unused runway and terminal capacity.

CM Quincy sent the attached FAA announcement. The preliminary arrival reduction is said to be ~24, or a operations per hour rate maximum now between 124 and 136. The variance is because some departures can be fit in, depending on how arrivals are spaced and if aircraft are ready to depart. Still, it is possible that some semblance of noise-abating departure profiles can be restored,

We do not want to sat "We told you so," because we want the other shoe to drop and hope for the MAC's support. Chair Boivin's suggestion that the Commission might impose financial incentives could be more effective if the incentives were for larger aircraft or more seats on most flights for O&D passengers. In the noise reduction context, fewer operations at peaks are more effective than source-noise reduction (the Stage 4 fleet notion).

MAC staff has championed the use of less-noisy engines and aircraft. Unfortunately, newer aircraft are designed for shorter-than-MSP's runways, heavier loads, and more thrust. The time and distance to a neighborhood is the principal cause of increased overflight noise -- time to climb.
