Planned Runway Closures

DFW Airport has planned weekend and/or more extended closures in 2018 in order to fulfill necessary maintenance and inspections related to airfield lighting, equipment, markings, signage, and pavement work.  Weekend runway closures are typically scheduled from Friday at 10:00 pm through Sunday at 4:00 pm, subject to favorable weather conditions.  A Go/No-Go decision is made prior to each affected closure as to determine if the conditions are favorable for the planned closure.  If runways cannot close on a weekend as scheduled due to weather or other factors, additional weekend closures may be required.  The schedule for any upcoming runway closures or changes in typical operation is noted below.  We will update this site as more information becomes available

DFW would like to inform you of the upcoming runway rehabilitation work of Runway 17C/35C in March 26 – December 8 that could affect air traffic in your vicinity.  This project is part of DFW Airport’s 10-year Infrastructure Rehabilitation program to address runways and taxiways that will need significant rehabilitation work. DFW Airport will begin major rehabilitation work on the m Runway 17C/35C on May 24. This work will include partial closures for a few months, followed by full closure of the runway beginning in August. DFW Airport’s engineers have discovered a way to complete the necessary work, while only having the runway closed for four months. This is normally a two year process. The work consists of replacement of the center third of the runway, about 6000 feet long and 50 feet wide, reaching a depth of more than three feet of sub-base, cement treated base and concrete. Afterward, the runway will be resurfaced with polymer-modified high performance black asphalt, designed for strength, flexibility and weather resistance.

 

The Runway 17C/35C will be phased as follows with periods of nighttime, partial and full closures to reduce overall time of the full runway closure and minimize operational effects onto surrounding communities.  Some of the preparatory work, which includes some night closures, began on March 26th.  The extended partial and full runway closures begin on May 24th and extend through November 16th.  The following is the schedule for all phases of the runway project.  We have color coded each phase and provided details of what to expect during each phase.

Runway 17C/35C Closure:

 

DFW is planning the closure of Runway 17C/35C from March 26th at 10PM through Sunday, December 8th at 4PM. This is to accommodate the rehabilitation of this runway, which entails the following:

·         Replacement of the center third of the runway, about 6,000 feet;

·         Asphalt resurfacing of the entire runway length;

·         Rehabilitation of the parallel taxiway, Taxiway M (This work will be done after the runway reopens).

Additionally, in order to avoid future runway closure and related impacts, DFW also plans to concurrently:

·         Install Runway Status Light System;

·         Build a portion of Northeast End-Around Taxiway that is within the runway environment.

 

A Fact Sheet about the Runway 17C/35C Project is available, detailing the project, including its schedule and what to expect during the project.  We also outlined the anticipated effects on runway use below.

 

What to Expect: 

The weather forecast is not known for the majority of the closure period.  In general, because aircraft take off and land into the wind, when winds are southerly aircraft take off to the south and land from north to south.  When winds are northerly, aircraft take off to the north (or northwest in the case of the use of Runway 31L) and land from south to north.  Keep in mind that surface winds don’t always dictate flow as winds above the surface and/or operational needs can affect the direction for which aircraft take off and land.

 

During each phase of the project, the following runway utilization is anticipated:

 

Potential Nighttime Closures (Mar. 26 – May 24 & Nov. 16 – Dec. 8)

·         Runway 17C/35C may be closed to all traffic at night

·         The use of all arrival runways during 10 PM through 7 AM may potentially increase

·         Some night closures of Runway 17R/35L (Departure Runway) may be needed to pull electrical under runway.  One weekend closure already occurred April 14/15th (previously messaged). 

·         North Flow:  When the runway is closed at night and the winds are out of the north:

o   Arrivals will shift from Runway 35C (arrival runway) to other runways resulting in increased operations on those runways:

§  Runway 35R and 31R (arrival runways) on the east side;

§  Runway 36L on the west side.

o   East side departures will remain on Runway 35L.

·         South Flow:  When the runway is closed at night and the winds are out of the south:

o   Arrivals will shift from Runway 17C (arrival runway) to other runways resulting in increased operations on those runways:

§  Runway 17L (arrival runway) on the east side;

§  Runways 13R and 18R on the west side.

·         East side departures will remain on Runway 17R.

·         Keep in mind that surface winds don’t always dictate flow as winds above the surface and/or operational needs can affect the direction for which aircraft take off and land.

Partial Closure (May 24 – Early Aug.)

·         Runway 17C/35C will be open between Sunrise and Sunset;

·         Runway 17C/35C will be closed to all traffic from Sunset to Sunrise;

·         Runway 17C/35C may be closed during periods of inclement weather and/or poor visibility;

·         17C/35C will be available for some aircraft arrival operations during the day (Sunrise to Sunset); however, the arrivals will be less than typical.  Thus, the use of all other arrival runways may increase, including during nighttime hours;

·         North Flow:  When the winds are out of the north:

o   Arrivals shift from Runway 35C (arrival runway) to other runways resulting in increased operations on those runways:

§  Runway 35R and 31R (arrival runways) on the east side;

§  Runway 36L on the west side.

o   East side departures will remain on Runway 17R/35L.

·         South Flow:  When the winds are out of the south:

o   Arrivals shift from Runway 17C (arrival runway) to other runways resulting in increased operations on those runways:

§  Runway 17L (arrival runway) on the east side;

§  Runways 13R and 18R on the west side.

o   East side departures will remain on Runway 17R.

·         The shifts in aircraft operations to other runways during the partial closure may primarily affect the cities of Irving, Coppell, and Lewisville. Southlake, Grapevine, Trophy Club, Westlake, and Flower Mound could also experience some additional aircraft traffic.

·         Keep in mind that surface winds don’t always dictate flow as winds above the surface and/or operational needs can affect the direction for which aircraft take off and land.

Full Closure (Early Aug. – Nov. 15)

·         Runway 17C/35C will be closed to all traffic

·         Operations will shift to other runways increasing operations on those runways, especially RWY 17L/35R, primarily affecting Coppell and Irving

·         Potential for increased use of all arrival runways during 10 PM – 7 AM

·         North Flow:  When the winds are out of the north:

o   Arrivals will shift from Runway 35C (arrival runway) to other runways resulting in increased operations on those runways:

§  Runway 35R and 31R (arrival runways) on the east side;

§  Runway 36L on the west side.

o   East side departures will remain on Runway 17R.

·         South Flow:  When the winds are out of the south:

o   Arrivals will shift from Runway 17C (arrival runway) to other runways resulting in increased operations on those runways:

§  Runway 17L (arrival runway) on the east side;

§  Runways 13R and 18R on the west side.

·           The shifts in aircraft operations to other runways during the closure may primarily affect the cities of Irving, Coppell, and Lewisville. Southlake, Grapevine, Trophy Club, Westlake, and Flower Mound could also experience some additional aircraft traffic.

·         Keep in mind that surface winds don’t always dictate flow as winds above the surface and/or operational needs can affect the direction for which aircraft take off and land.

 

We have included graphics that provide a visual as to how air traffic will be redistributed during the partial and full closure.

High Velocity Winds

.
Aircraft normally will take off and land into the wind. In the Metroplex, the winds are from the south about 70% of the time (South Flow) and are from the north about 30% of the time (North Flow). DFW typically uses its north/south runways for most arrivals and departures. Aircraft also arrive on the diagonal runways, that is, from the northwest on Runway 13R/31L in South Flow, and from the southeast on Runway 13L/31R in North Flow. On occasion, DFW will experience high velocity cross winds from the west or northwest. This condition is referred to as West or Northwest Flow. Strong west cross winds limit the use of DFW's north/south oriented runways. During West Flow,the FAA necessarily uses the diagonal runways for arrivals and departures in order to align the aircraft to the extent possible with the prevailing, high velocity winds. This situation occurs rarely but when it does, you may notice jet aircraft departing to the northwest from both diagonal runways. DFW and the FAA collaborate proactively on the possible use of the diagonals during the strong cross wind and use the diagonals when winds and safety warrant.
