11. Who issues the “descend via” clearance?2. What altitudes are the arrivals crossing at?3. Who does the metering and where are the new arcs located?

Introduction:This presentation has been developed to brief all NAS users and affected FAA facilities on the Traffic Management Initiatives (TMIs) planned during the initial “Break-in Period” associated with the implementation of the new MSP RNAV STARs on 3/24/15.In addition, ZAU will be supporting this project by using TBFM to Adjacent Center Meter (ACM) MSP arrivals using new Outer Meter Arcs (OMAs) . Six operational areas (3 in ZMP and 3 in ZAU) will be metering to these new OMAs for the first time.

NextGen Goal: Performance-Based Navigation (PBN)

PBN is a framework for defining performance requirements in “navigation specifications”. The two main components of PBN framework are Area Navigation (RNAV) and Required Navigation Performance (RNP). NextGen solutions are dependent on RNAV and RNP implementation as enabling technology in the NAS, including:

•Trajectory-Based Operations (CTOP)•Arrivals/Departures at High-Density Airports•Flexible Terminals and Airports•Optimized Profile Descent (OPDs)

- These RNAV STAR/OPD procedures are being introduced at 90 airports in the NAS. At the larger terminal facilities these projects are called Optimization of Airspace & Procedures in the Metroplex (OAPM).

Both the MSP RNAV STARs and the ZAU ACM projects are important

components of NextGen:

11. Who issues the “descend via” clearance?2. What altitudes are the arrivals crossing at?3. Who does the metering and where are the new arcs located?

“The FAA has created the OAPM initiative to optimize the airspace, and estimates that the pilot project in Houston will translate to an estimated annual savings of 2.5 to 6.9 million gallons of fuel and reduces carbon emissions by 26K to 71K tons.”

“Other Metroplex studies show annual savings across the NAS of up to 67.7 million gallons of fuel and 679 metric tons of carbon dioxide”

- From 3/24/15 - 4/21/15, the arrival rates at MSP will be reduced due to implementation of the new MSP RNAV STARs. This reduction is necessary to allow pilot and controller familiarization with new Optimized Profile Descents (OPDs), airspace changes, and new Time Based Flow Management (TBFM) metering procedures. The rate reduction is projected not to exceed four weeks, and after each week the Implementation Teams from M98, ZMP, and ZAU will collaborate to review the impact and look at reducing these Traffic Management Initiatives (TMIs) accordingly.

- Controllers in ZMP Areas 2 & 3, that abut M98’s airspace, will be responsible for issuing the OPD. When the ZMP controller issues the “descend via” clearance, the aircraft is cleared from top of descent all the way to 7000ft at the end of the downwind leg inside of M98’s airspace. The receiving M98 controller will assign the specific RWY and transition the aircraft from the downwind portion of the OPD to the base and final phases of the approach.

- In addition to the OPD procedures, six areas of specialization (three in ZMP, three in ZAU) will be using TBFM to meter MSP arrivals to new Outer Meter Arcs (OMA) located outside the OPD’s top-of-descent. The controllers in these six areas have not previously metered these MSP flows.

- The TMU’s at M98, ZMP, and ZAU understand the complexity and impact these new OPD and TBFM procedures have on the workforce. It is TMU’s goal to implement the TMIs necessary to provide all controllers connected to this project the opportunity to be successful, while at the same time providing the best possible service to all NAS users.

Background/Purpose For These “Break-In” Traffic Management Initiatives (TMIs) :

11/1/13 6

At MSP, the RNAV STARs will be published on 3/5/15 but will be NOTAMed OTS (“ATC ASSIGNED ONLY”) until 3/24/15. Operators are reminded to continue

file the legacy STARs through 3/23/15.

When the ZMP controller issues the OPD, the aircraft is cleared from top of descent….

11/1/13 7

…all the way to 70 at the end of the downwind leg inside of MSP APCH…

70

…where the RNP approach segment

begins

11/1/13 8

However, the RNP segments won’t be published/implemented until 4/30/15

9

A couple of important items

to note….

11/1/13 10

The HELLO transition to the BLUEM STAR will be NOTAMed “ATC ASSIGNED ONLY”

11/1/13 11

Operators can now file the KKILR RNAV STAR . This replaces the WILDD arrival which was

previously ATC assigned only

11/1/13 12

The KAMMA.. JERMN transition to the MUSCL STAR will also be NOTAMed “ATC ASSIGNED ONLY”. MSP arrivals entering ZMP from ZAU via the KAMMA intersection should all be filed on the KKILLR RNAV STAR.

New ZMP and ZAU TBFM Freeze Horizons are now set to 230 (south) to 265 (east) to 300 (northwest)

New Outer Meter Arcs (OMA) New Outer

Outer Arcs (OOA)

Six areas of specialization (3 in ZMP, 3 in ZAU) will be using TBFM to meter MSP arrivals to these new Outer Meter Arcs (OMAs) located outside the OPD’s top-of-descent.

Internal departures can expect ESP delays as they are scheduled into the TBFM timelines.

15

Another important thing to note is that the MSP arrival demand has a number of high volume spikes followed by steep valleys, i.e. room for recovery. Operators are being encouraged to de-peak their departures times to avoid departure delays during these spikes.

Traffic Management Initiatives (TMIs) To Support The MSP RNAV STARs Break-In Period

The ZMP MSP TMC will initiate the “ZMP/ZAU ACM Metering Plan” as follows:

1. Each evening after 04Z the Command Center will send out the MSP mandatory city-pair preferred routes advisory for the following day from 0900Z-0400Z.

2. The ZMP MSP TMC will enter the MSP AAR, allocate runways, re-sequence and broadcast the TBFM meter list, then notify ZAU TMU at least 60 minutes prior to the beginning of each ACM session . Any additional “ripples” in the meter list must be pre-coordinated with ZAU TMU and all affected areas in both centers.

3. An open phone bridge will be used for all TMU–to-TMU coordination.

4. The TMUs will use shared FEAs and TBFM timelines with associated trigger values to monitor arrival volume

5. Once MSP arrival FEA trigger values are exceeded, the TMCs will coordinate expanded MIT, or coordinate fix balancing/off-load routes to mitigate excessive MIT pass-backs.

6. ZMP and ZAU TMUs will manage internal departure demand and coordinate possible off-load routes.

7. ZMP and ZAU TMUs will coordinate ground stops when needed and possible short term EDCT programs.

8. If the TMIs in use cannot keep TBFM Timeline delay values at a manageable level and the delay values trend towards imminent holding, the ZMP MSP TMC will coordinate “ Knock It Off (KIO) – Metering”. When “KIO – Metering” is invoked the ZMP MSP TMC will coordinate the time or aircraft where metering at the OMAs is suspended, leaving ZMP Areas 2 & 3 to set up their holding stacks and meter out of the hold, still issuing OPDs. The ZMP MSP TMC will coordinate when OMA metering will resume.

Shared FEAs are monitored for trigger values exceeding “8”on all flights outside of the Freeze Horizons (FHs), where the fix-balancing reroutes need to take place. ATC should avoid reroutes inside of the FHs. TWRs will be on Call For Release (CFR) and TMCs should release internal departures judicially, watching both the FEAs and TBFM timelines.

20

In this example 2 AC offloads from the KKILR in the 1245 bucket (“9”) to the MUSCL would help, however the same offloads in the next time block would push the MUSCL from a 7 to an 8. In that case ZMP could offload a few AC to the north via HOCKY.BAINY1, to make room for the extra volume offloaded north from the KKILR. Likewise on the BLUEM – AC could be fix-balanced to the NITZR, and if needed, NITZR TFC down in ZKC could be moved to the TORGY. We will look for these off-load opportunities for both airborne flights and departures to take advantage of unused capacity. Also, in this example we might be looking at a ground stop (450 mile scope) from 1245-1315Z. ***Operators should be fueled for fix-balancing reroutes to the adjacent RNAV STARs ***

In addition to the FEAs ,TMCs will also be monitoring TBFM timeline values.

You may have to dig a little to find the actual APCH plates. On the first page, scroll to the bottom where it lists the STARs (example “STAR BLUEM (RNAV) ONE”), then click on the bottom file listed under each for the “Prototype” plates.

Remember, the new MSP RNAV STARs are published on 3/5/15, but NOTAMED OTS (ATC ASSIGNED ONLY) until 3/24/15. Please continue to file the MSP legacy STARs thru 3/23/15.

Thank you!
