Flow Management Position


For controllers subject to FMP, please see at the end of this page for abbreviated procedures you can expect.

ALB = Arrival Load Balancer

1. Objective and Responsibilities

As Flow Manager (EKDK_FMP) Your objectives and responsibilities in the time period FMP active traffic flow is in sequence of succession:

  • Establish Flow rates via ALB consistent with traffic demands.
    • Chapter 2
  • Manage flow inbound to copenhagen by use of the "BIDE" Acronym
    • Balance
    • Interrogate
    • Distribute
    • Equalize

Details of how to achieve all is specified below and is continuously updated.

Please refer to this documentation every time before you log onto EKDK_FMP

2. Flow Rates into TMA

Adjusting the flow rate of aircraft handed over from the 5 ACC sectors (DK_E, DK_D, DK_B, MML, MMK) into TMA. They are managed and communicated via the ALB, and has several pre-defined scenarios.

2.1 Standard Separation (Green Flow)

This scenario used from the beginning of event until hourly rate becomes more than 30/hr.

Arrival rate 150 flights / hr

2.1.1 Required Rates

All ACCs have standard handovers as pr. LAI/LOA of 10nm with leading aircraft faster, or 5nm with leading aircraft fast if prior coordination has been obtained.

This is valid for all sectors.

2.1.2 Thoughts and considerations

This rate is being used when so little load will be on the TMA (smaller than 30/hr) that the distribution of flights are negligeble.

Either via manual calculations, ALB or MAESTRO, fine tuning of timings, and speed restrictions can be utilized with this rate. Neither are mandatory, but may make APPs use of vectors more efficient.


2.2 Reduced flow (Yellow Flow)

This scenario used from when ALB advise of an hourly rate of MORE than ~30/hr, but with TMA consitent load factor of 12 airplanes or less

Arrival rate 56 flights / hr

2.1.1 Required Rates

ALB has several scenarios for rates distribution based on the load factor for STARs.

Load factors are displayed in percent for the next 30 minutes.

2.1.2 Thoughts and considerations

Invoke LOA point on EDYY and EDWW to increase separation to minimum 25nm.

2.3 Peak Flow (RedFlow)

This scenario used from when ALB advise of a TMA load of 12 or more AND 30flight/hr. or more inbound.

Arrival rate 45 flights / hr

2.1.1 Required Rates

ALB has similar scenarios for Peak flow as well. 12 or more planes in TMA signifies that TMA has reached capacity and immediately action is required to reduce flow rate to a level that is sustainable and comparative to what the TMA can land

2. Management

Use the Acronym BIDE to remember your tasks

2.1 "BIDE"

In addition to managing the flow rate, you need to manage different aspects of the night in regards to traffic. For an attempt to make it easier to remember the acronym BIDE can be used, to remember the four different areas you must manage.

  • Balance
    • Prioritise a specific STAR via the ALB when load is disproportionally heavy
  • Interrogate
    • Coordinate with Uppervarious upper ACCs (DK_A, DK_N,DWM,YY) to achieve
  • Distribute
    • Re-Route from East to West and West to East.
  • Equalize
    • Ensure that releases from holdings are consistent with who has been there the longest from each side

All is explained in providingDetail delaybelow

vectors

2.2 Balance

2.2.1. Balanced or prioritized flow

From the very beginning of the event you need to identify, via ALB or your screen a potential situation where you need to switch the vast majority of the flow to one STAR in order to helpavoid achievinga thetotal required separation as early as possible

Invoke LOA pointcollapse on EDYYthat and EDWW to increase separation to minimum 25nm.sector.

2.

Please Yellownote operational rate scenario

When your operational rate changes from white to yellow or red, you need to move to this scenario

WEST FLOW

To choose appropriate scenario. This is tricky but important. Consider following things:that:

  • PreferedThe ratestate atof ERNOVimbalanced flow is 1so every 10min. Isextreme that possible?
  • Isit Approachshould not verybe busyused andfor final lessmore than 12nm?15minutes.
    • with 2 min / 10nm separation from the prioritized STAR you get 8 aircraft in in that time, meaning a hugely efficient thing.
  • WillMAKE itSURE staythe yellowcontroller foris atusing leasttight anotherspacing
    • Consider 30-45telling minutes?10nm spacing, down to 7.5 pre-coordinated by you, in order to ensure lots of traffic gets is.
  • If controller is NOT adhering to the tight spacing consider giving additional individual releases to balance things out.

If

2.2.2. Yes to all? Take Variation 1

  • ERNOV is very busy?
  • Approach looks very loaded and final is quite long
  • Relatively inexperienced controllers
  • Red area is approaching fast
  • Yellow area is very close to 42 movements aka. borderline turning red.

If Yes to just some? Take variation 2

Is the Red area approaching fast, or is it a long stretch


Variation 1ALB

This variation keeps a higher than capacity arrival rate (36/hr) to keep flow coming from TUDLO/TESPI while de-prioritizing ERNOV

*OnlyThis means that for PRIORITY STAR that:

  • Prioritized STAR has 10nm /2min separation
    • Tell ACC sector that 7.5nm is pre-coordinated by you with APP
  • All other STARs on that side are STOP, however on WEST STREAM you have freedom to do individual release
    • Priority TUDLO/TESPI has an hourly rate of ~36 an hour, meaning you can release ERNOV or TUDLO flights meaning you can release ~2-3 airplanes during a 15 minute period to your liking depending on where its needed the most.
  • For TUDLO/TESPI priority MONAK still release with 6min due to the perceived threat of a stop at MONAK
    • This can be altered if required by you if required

This means that for PRIORITY O/W that:

  • Priority W considers that TUDLO stream gets re-routed via Vectors to the east side for sequencing and general balancing.

  • Priority-O will only be in case of light load being heavily on ERNOVWEST relative to TESPIstream and TUDLO.high Notload usual.

AskIt Muritzis vital that you talk to startthe stackingUpper ACCs both domestic and foreign to pre-sequence and help out your ACCs. These are in particular following things in order of importance based off experience and feedback.

  1. MONAK: Talk to DWM (Muritz sector) and get them to stack airplanes from FL200 up to FL270 ifwhen 25nmyou cannotsee a potential overload situation.
    • DO NOT rely on EKDK_B to do this as he will be maintained.busy
    • DO NOT rely on DWM to do this as he will not have an overview of what is needed
  2. Establish Secondary holdings to stop flow into EKCH
    • For TUDLO establish enroute hold at TALSA when no more entries towards EKCH is accepted by you
    • For TESPI establish enroute hold at AAL when no more entries towards EKCH is accepted by you
    • For MONAK, tell DWM (Muritz) that no more inbound are accepted at this time (15min-30min. notice required) and advise to establish an enroute hold as desired, or start diverting.

2.4 Distribute

2.4.1 General

This is about distributing flights to which arrivals, or more precise when to REdistribute arrivals to other STARs.

We want to have an ~55/45 split on EAST/WEST. You should consider distributing flights to other STARs when you:

  • See an imbalance or empty STARs with other STARs full but no extreme enough to warrant a "Prioritized flow".
  • A potential overload situation can happen on a STAR if immediate action is not taken
  • Tactical distribution for reasons of your discretion

2.4.2 Techniques

Changing a STAR must ALWAYS adhere to the following.

  • Ask the Sector which will get the aircraft to request a tactical direct to their sector
  • Ask the sector to change the flightplan route to be only the point of the new STAR.

Following flights are highly effective an recommended

1. EDDH via MONAK - Distribute to TUDLO/TESPI

  • EDDH flies at FL230 and hence creates all sorts of issues for DK_B. Consider distributing to TUDLO or TESPI depending on which STAR has the most space (Can be issues as an ECFMP as well)
  • Consider whether to keep af FL230 or climb to FL290 to be distributed to EDK_A

image.png

2. EDWW via MONAK from T208

  • In a potential MONAK overload situation flights via T208 can be effectively rerouted to TIDVU for holding there. A good direct to propose is "BAKLI" as this is a valid point for the direction

 image.png


Considerations

  1. MONAK:

    StartTalk askingto EKDK_V,DWM EKDK_A,(Muritz EDYYsector) forand minimumget speeds,them to stack airplanes from FL200 up to FL270 when you see a potential overload situation.

    • DO NOT rely on EKDK_B to do this as holdings will come.

      Prepare EKDK_A and EKDK_V that when holdings are coming they should clear airplanes into holdings.

      Consider diversions from EDYY to TUDLO to avoid MONAK chaos

      Consider diversions from EDWW_M to TIDVU to avoid MONAK chaos


      Continue to run this scenario until no longer possible, and holdinghe will be busy

    • DO NOT rely on DWM to do this as he will not have an overview of what is needed
  2. Establish "imminently"

    Secondary


    holdings to stop flow into EKCH
    • For TUDLO establish enroute hold at TALSA when no more entries towards EKCH is accepted by you
    • For TESPI establish enroute hold at AAL when no more entries towards EKCH is accepted by you
    • For MONAK, tell DWM (Muritz) that no more inbound are accepted at this time (15min-30min. notice required) and advise to establish an enroute hold as desired, or start diverting.

3. Holdings (Red) scenario

When it becomes APPARENT to you that with the rate given EKDK_D/E/B cannot maintain separation, and holdings are needed!

You will know holdings are needed before BIDE. Advise them to be ready for it.

WEST FLOW

Start when it becomes apparent by taking a talk with EKDK_A_CTR and EKDK_V_CTR

Advise them to:

  • Clear aircraft onto the arrival
  • Clear aircraft into the hold
  • Update the tag so aircraft enters holding list

Consider if holdings get very busy for EKDK_A/V to:

  • Descend aircraft to the lowest available holding level
  • Enter holds above Fl285, and handover as needed

Release and EATs.

Keep previous flow rate until APP appears very full.

Ask all sectors to enter EATs as follows:

ERNOV

count 5-10 min from beginning of hold and then assign EATs with 10min interval independently of what goes on with EKDK_E/D

TUDLO/TESPI

Identify via the holding list the distribution of traffic on each arrival.

  • ETOs are within approx 10min of eachother = Give the rate as pr. table above
  • ETOs are heavily skewed to one of the other = Hold one completely and half the separation time for the other.

Example of skewity.

Lets pretend time is 1930z for first release:

Ask each BIDE sector over text to enter following information to their EATs

image.png

This scenario was the 6,6,10 scenario with only one holding at the time, meaning 3min release.



EAST FLOW

east flow we must take following considerations

  • TIDVU will never be more busy than MONAK
  • MONAK gets very difficult very fast
  • Keeping MONAK holdings manageable is a top priority

When holdings are imminent, keep very vigilant of following:

  • Get an overview if traffic from Muritz will be managable
  • Prepare to give stacked levels to Muritz in accordance with the holding
  • Get an overview of IF diversions to other STARs are needed
    • Divert to other STARs ONLY for the purpose of keeping holding managable. Dont worry about traffic balancing.

Imbalance mitigation

It can happen that one particular STAR is so overloaded compared to others that immediate priority is needed to avoid overflow of holdings. this is mainly apparent when:

  • MONAK early in the event
  • TESPI when ENGM/ENBR traffic is heavy.

If condition allows then go a heavily prioritize the STAR needing direct priority. Do this for no more than 15 minutes to avoid overload at other STARs. In this case utilize following.

Holding notes

Please in your holding list go to "VIEW" and click on "EAT" to show EAT column. Please put in the EAT as directed by EKDK_FMP (EAT=Expected Approach time, and is the time you may clear an aircraft to pass the inbound fix (KOR, TNO, NEKSO).

Imbalance Mitigation

For a duration of no more than 15min. imbalance mitigation can be used to correct for extreme load on one particular STAR.

  • You STAR is the subject?
    • Apply 7.5 - 10nm separation:
      - less than 7.5nm must be coordinated
      - 7.5nm and above is PRE-COORDINATED by FMP
  • another STAR on your side (East/West) is the subject?
    • Stop all approaches. Hold indefinitely
  • another STAR on opposite side (East/West) is the subject?
    • EAT as assigned by EKDK_FMP. Keep a look out.
