Now of the 110 airplanes, 70 of them will be delayed. Low clouds and high winds have moved in and now airport A can only land 40 airplanes per hour. The helpful airlines have scheduled 110 airplanes to land in one particular hour (no slots at this airport!). In good weather, airport A may land 90 aircraft per hour. Runway closures, accidents, construction, plowing/de-icing can all cause these delays also. The reason is most often weather at the destination airport. These are like the Ground Stops but the airport knows it can accommodate you, just not exactly when you planned to be there. They are subject to cancellation at any time, or extension with updated in another 60 minutes.
Sfo atc delay update#
Ground stops are issued with update times, usually (in my experience) 45-60 minutes later. Sometimes only T1 departure airports are affected by a ground stop, and sometimes it is everyone. T2 ARTCCs are those bordering the T1 ARTCCs and so on. In short, the T1 ARTCCs are those that directly border with the ARTCC of the destination. You'll note that many times you'll see ground stops described as "Tier 1", "Tier 2". If planes cannot depart, there may be nowhere to park arrivals. If you can't land, you probably shouldn't take off. Aircraft are already in holding patterns and they are running low on altitudes/fixes to put us, and/or those of us in holds are getting close to diverting for fuel.
In this case, they will disallow all planes destined for that airport to take off from wherever they are. Your destination airport cannot accommodate arrivals - at all. Has good quotes and I'll supply some of the direct knowledge he requested.
