Weather Reroutes, Simplified
During normal operations, the BOS arrivals fly the Gardner3 Arrival route (Pink line). Westbound departures (Blue line)fly over MHT to SYR then somewhere farther west. A typical weather pattern, shown above, such as today, prevents Gardner3 arrivals from getting to Boston safely, so they are rerouted over Kennebunk, ME and then a fix called SCUPP and then direct Boston from the northeast (Red line). This works out well for the arrivals, obviously, but please note how the arrivals and departures from Boston now cross just east of SYR. This situation puts a lot of extra work load on the UCA/ART sector where this occurs.
Now remember that when weather sets in it never affects just one airport. This one new traffic flow situation is multiplied by the number of airports needing reroutes, then subtract all the airspace that is unusable due to the actual weather. I'm not very good at math, but I believe that adds up to a long night.
Till next time...
PS. I'm roadtripping to Denver for my brother's college graduation for the next two weeks so here is a double dip of blogging for today!
