Ground Delay Affecting COU
Affected Flights FlightStats attempts to match up the airport delay with the flights that may be or have been affected by the delay. To see what flights may be or have been affected by the delay click on the graphic in the flights column. Results are more reliable once the delay has ended. Active delays or ones that have no expected end time may display flights that, in the end, were not affected by the delay.
Status Delays that are currently in effect have a status of 'Active'. Delays that have ended have a status of 'Cancelled'. Delays that are re-issued with new information have a status of 'Invalidated' and are grouped together with the re-issued delay. These groupings are represented by the graphic and can be seen by clicking that graphic.
Airports experience general arrival and departure delays for a number of reasons, weather and congestion being the most common. These delays are usually temporary in nature. If arrival delays becomes worse, air traffic control may issue a ground stop or ground delay program.
Ground Stops are implemented by air traffic control when the amount of arrival traffic is projected or has exceeded the capabilities of the airport for a short period of time.
The delays are issued for a period of time and affect flights destined for the airport but that have not yet departed. Flights are held at the departing airport until the end
of the ground stop. Ground stops may or may not affect different regions of the country. For example, ground stops issued in SFO may affect other airports on the west coast but are
less likely to affect airports on the east coast. This is because flights departing from longer distances will arrive at times later in the day when the airport is projected to be able
to handle more arrivals. If the projected time period of capacity problems is expected to be longer, air traffic control may issue a more sophisticated ground delay program for the airport.
Ground Delay Program
Ground Delay Programs are implemented by air traffic control when the amount of arrival traffic is projected or has exceeded the capabilities of the airport for a long period of time.
These are usually a result of adverse weather conditions. The delays are issued for a period of time and affect flights destined for the airport but that have not yet departed.
Flights are issued an Expected Departure Clearance Time (EDCT) at their point of departure and they are not permitted to depart until that time. The ECDTs are calculated in such a way as to control the rate that traffic arriving at the affected airport so that demand does not exceed the arrival capacity of the airport.
Much like ground stops, ground Delay Programs may or may not affect different regions of the country.
While rare, airports are closed for a variety of reasons including seriously bad weather, aircraft accidents, etc... The airport issues a closure time and an estimate on when it will re-open.
Deicing involves spraying various chemicals on the airplane to keep the plane safe for travel in cold weather. FAA regulations require the deicing process to be completed no more than five minutes before takeoff. Deicing also takes place with all passengers on board and usually, but no always, means the flight will be late departing the runway.
It also usually means that planes are at their gates for a longer than expected time, and thus may result in some congestion at busy airports with arriving flights waiting for departing flights to leave. How much a flight may or may not be delayed by deicing depends on the efficiency of the airline crews, the frequency of cold weather at the airport, etc..
