Expect Departure Clearance Time (EDCT)

Abnormal Procedures (Procedural)

 


 

The Source of the Delay

Traffic Flow Management

images

Traffic Flow Management (TFM) is a collaborative process:

  • Tower
  • TRACON
  • ARTCC
  • ATCSCC (ATC System Command Center)

The delay can be caused by weather, volume, equipment, runway issues, aircraft accidents, special events, etc. Over 70% are caused by convective activity.

Weather

Knowing the weather at your departure point, en route, and destination can help you predict delays. The FAA is used the Collaborative Convective Forecast Product (CCFP), which you have access to: http://aviationweather.gov/products/ccfp/

images

They also use something called the Localized Aviation MOS Program (LAMP), and you can see that at: http://www.nws.noaa.gov/mdl/lamp/convection.php.

Delays

Delays, whatever the cause, are normally posted on the FAA's Operational Information System: http://www.fly.faa.gov/ois/

Ground Delay Programs (GDPs)

Manages traffic to a specific airport — only traffic TO the airport, departures are not impacted.

Can avoid by:

  • Using another airport
  • Changing departure time earlier or later

Can minimize the impact by filing your flight plan earlier — Up to 24 hours early — "Known Demand" has priority over "Pop ups."

Late filers are penalized by adding the average delay to the first available slot.

Airspace Flow Programs (AFPs)

Manages traffic through a block of airspace and impacts all airports in that area. Takes a line, such as a center boundary, and manages traffic based on their arrival time at that line.

Ground Stops

These are used at specific airports to institute an immediate reduction in demand for sudden weather changes, equipment outages, or other incidents. The FAA says they are normally short-term, one to two hours. All traffic is held at the point of departure.

Finding Out Ahead of Time

EDCTs

images

You can look up your own EDCT: http://www.fly.faa.gov/edct/.

Flight Planning Service

images

Some flight planning services, such as ARINCDirect, will automatically notify you if your flight plan becomes subject to an EDCT.

Current Restrictions

You can find the currently instituted restrictions at: http://www.fly.faa.gov/current_restrictions/jsp/index.jsp.

Getting Around the Delay

Reroutes

images

The FAA can advise you of a possible reroute but quite often you are just left waiting.

National Playbook Routes

images

You can find alternate routes that the FAA will approve in the National Playbook, available here: http://www.fly.faa.gov/PLAYBOOK/pbindex.html.

Example: KBED to KBCT

images

Let's say, for example, you are trying to get from KBED to KBCT and it looks like the convective weather along the east coast might shut down all air traffic from north to south. You hope to get your normal routing so you file that:

KBED DCT PUT CCC GEDIC J174 DIW AR19 AYBID CAYSL3 KBCT

Fuel: 6786

Time: 2+21

From hard experience, you know that if a delay kicks in, you could be stuck in the chocks for three or four hours. Wouldn't it be nice to have a hip pocket flight plan that gets you to your destination sooner?


images

The National Playbook includes possible solutions under "Regional Routes" and a point off the coast called AZEZU. Scrolling down under "ROUTE TO DESTINATION" you see the following:

  • DESTINATION: KBCT
  • ROUTE: HANRI M201 JENKS AR19 AYBID CAYSL3

images

Using the "add to route" function of your flight planning service, you come up with a new route:

KBED HNSCM8 SSOXS SEY BERGH L454 ATUGI M201 JENKS AR19 AYBID CAYSL3 KBCT

Fuel: 7314

Time: 2+34

At the cost of just over 500 pounds of fuel and 13 minutes you could save three hours of APU time and fuel as well as get to your destination hours sooner. If you call your flight planning service and have them cancel the first flight plan and file the second, you could be on your way.
