Intro to D10
Intro to D10
D10 is responsible for the airspace surrounding the Dallas/Fort Worth International Airport (DFW). This airspace extends 50-to-60 miles in all directions, up to 17,000 feet. The Class Bravo airspace is a complex, high volume, centrally situated piece of the national airspace system in the heart of North Texas. D10 is responsible not only for the primary airport, which is home to American Airlines, but also to Dallas Love Field (DAL), which is home to Southwest Airlines. These two airports are located just over five nautical miles from each other, creating a very unique and complex arrival and departure arena for the two major airline hubs.
In addition to DFW and DAL airports, D10 is the parent facility to 11 other towered satellite airports as well as numerous private and non-towered municipal airports. D10 controllers are responsible for a wide variety of aircraft types that range from military fighters, Boeing and Airbus air carrier types, to every imaginable aircraft in the general aviation fleet. Sequencing a Cessna 172 Skyhawk with a Gulfstream, Citation, or an F-16 is a daily occurrence.
Positions
Positions
Though the D10 may be considered complex, the manner in which it is staffed is broken down in a few basic categories: Departure, Feeder, Arrival, and Satellite. There are 17 total approved positions per the ZFW D10 SOP that may be manned. However, positions are combined on a normal basis to provide better staffing solutions for the airspace. Position names are shortened for documentation purposes in the sop.

Automated Terminal Proximity Alert
Automated Terminal Proximity Alert
Remember back when you were first learning about CWT and you saw something called ATPA mentioned? No? That's okay, it was only mentioned briefly and it was the second part of the presentation on CWT that is linked in S3 Unit 2, Lesson 3. It will be posted at the bottom of this block as well.
Automated Terminal Proximity Alert, or ATPA, is similar to the TPA cones or J balls that you may already be familiar with from other TRACONs*. If you aren't familiar with these, they can be individually placed on aircraft by typing *J3 or *P5 for the 3 mile "J ball" or 5 mile "bat", respectively. However, individually placing these isn't really efficient and inside of 10nm from the threshold, some runways can compress to 2.5nm separation anyway. That's where the "A" comes into play. Inside of certain regions inside the D10, ATPA cones will automatically be placed on trailing aircraft correctly sized for CWT (see how they're tied together?) and will shrink to 2.5nm on applicable runways. This feature does not only show a cone, it will also change colors to yellow (warning) or red (alert) if the aircraft pair will lose separation within 45 or 24 seconds, respectively. Additionally, mileage to the lead aircraft is shown in the trailing aircrafts datablock. NOTE: In order for this system to work, appropriate scratchpad entries have to be entered.
* As of the time of writing, ATPA is only supported in the D10 TRACON. Hopefully you have learned how to use J balls and bats in other places.
For your review, here is the CWT/ATPA Briefing. ATPA examples are on the last few slides.
