Splits
Departure Radar has a total of 3 possible splits:
DR1 (REG_L_DEP) 118.55
DR2 (REG_Q_DEP) 125.12
DR3 (REG_Z_DEP) 126.47
Normally, all departure airspace is combined on the DR1 frequency, but if a two-way split were to occur, the DR2 and DR3 airspace would be combined on the DR3 frequency, creating a DR1/DR3 split.
During events with low D10 staffing, Departure Radar can also be combined with Satellite.
Departure Gates/Fixes
All departure fixes are located on the "Sides" of the TRACON, and all arrival fixes are located on the "Corners." The Departure Fixes are laid out as follows:
The north and south side gates each have 4 departure fixes which serve both RNAV and Non-RNAV SIDs.
The east and west side gates each have 8 departure fixes (4 RNAV and 4 Non-RNAV per side).
Pilot-Nav SID Structures
DFW and DAL are the only airports in the D10 that have Pilot-Nav "RNAV off the runway" SIDs. These Pilot-Nav SIDs are designed with altitude restrictions so that approved separation can be maintained between DFW and DAL departures without controller instructions.
Hybrid and Radar Vectored SID Structures
Every other SID out of the D10 is either hybrid or radar vectored, and usually involves joining a radial to the applicable departure fix.
Problem Areas
As stated above, the "Climb via" Pilot-Nav SIDs out of DFW and DAL are designed meticulously to ensure separation. There are key areas where these SIDs cross other departures and arrivals with minimum separation. Controllers should be extremely vigilant in these areas to avoid conflicts caused by controller initiated climbs/route changes.
DFW downwind arrivals are descending to 12,000. Do not climb DFW departures above the assigned top altitude of 10,000 unless approved separation is guaranteed or they are clear of the feeder's arrival corridor.
2. (North Flow) DFW east gate departures and the ESNYE or EMMTT departures out of DAL operate in close proximity. Ensure that both DFW and DAL departures are climbing via in order to avoid conflict. Climb ESNYE and EMMTT departures after they are laterally clear of DFW departure routes.
High Side Dual Arrivals (HSDs)
Dual arrival routes are used to enhance arrival flow and capacity through specific corners of the TRACON. High side dual arrivals are ATC assigned STARs which go through the downwind corner posts of the D10. The following procedures shall be used when utilizing HSD arrivals:
High side duals should only be approved when demand exceeds capacity on the primary route. Departure demand at DFW and satellite airports shall be assessed prior to the use of HSD’s.
When high side duals are in use, DR-1/2/3 shall provide separation from high side dual route aircraft worked by FE-1/2 and/or FW-1/2.
Example of HSD arrival (CAINE2) in north flow
Working with Satellite Radar (Meacham & Dallas)
Satellite controllers are required to get departure releases from DR for jets departing satellite airports. Approve/Stipulate/Deny these requests to facilitate efficiency between satellite and DFW/DAL departures.
Departure radar only owns the departure ends of DFW and DAL. All other airports are initially worked by satellite, then handed of to DR for further climb instructions.
DFW Waiver 04-T-16D For Simultaneous Departures
This waiver authorizes DFW to conduct simultaneous departures from the 4 main parallel runways with course divergence of 11 degrees beginning no later than 10 miles from the runway end for RNAV equipped aircraft.
Practically speaking, this waiver allows simultaneous departures to be side by side all the way to LARRN/TREXX in south flow, and HAZKL/CUZEN in north flow.
