Flow Management Position
For controllers subject to FMP, please see at the end of this page for abbreviated procedures you can expect.
1. Standard separation scenario
This scenario used from the beginning of event until yellow operational rate is hitting
Lower
- EKDK_B: 10nm separation. Aim for 10-15
- EKDK_D: 10nm separation. Aim for 10-15
- EKDK_E: 10nm separation. Aim for 10-15
Upper
- EKDK_A: 15nm separation. Aim for 15nm, coordinate with EDYY to get as even a spread as possible.
- EKDK_V: 15nm separation. Aim for 15, try to get as evenly a spread as possible.
- EDYY_J/H: Min. 10nm separation. Try to as evenly spread as possible.
- EDWW_M: Min. 10nm separation. Try to as evenly spread as possible.
EKDK_A should coordinate with EDYY to the greatest extent possible.
2. Yellow operational rate scenario
When your operational rate turn away 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:
- Prefered rate at ERNOV is 1 every 10min. Is that possible?
- Is Approach not very busy and final less than 12nm?
- Will it stay yellow for at least another 30-45 minutes?
If 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 1
This variation keeps a higher than capacity arrival rate (36/hr) to keep flow coming from TUDLO/TESPI while de-prioritizing ERNOV
Sector | Separation (nm) | Separation (Min.) | Or | Separation (nm) | Separation (Min.) |
EKDK_E_CTR | 20nm | 4 | Or | 25* | 5* |
EKDK_D_CTR | 20nm | 4 | Or | 25* | 5* |
ESMM_K | -- | 10 | Or | 30* | 6* |
*Only in case of load being heavily on ERNOV relative to TESPI and TUDLO. Not usual.
Variation 2
Sector | Separation (nm) | Separation (Min.) |
EKDK_E_CTR | 30nm | 6 |
EKDK_D_CTR | 30nm | 6 |
ESMM_K | -- | 10 |
EAST FLOW
Sector | Separation (nm) | Separation (Min.) |
EKDK_B_CTR | 15nm | 3 |
EDWW_M | 25* | |
ESMM_L | -- | 10 |
Ask Muritz to start stacking to FL270 if 25nm cannot be maintained.
Considerations
Start asking EKDK_V, EKDK_A, EDYY for minimum speeds, 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 holding will be needed "imminently"
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.
The revert to flow rate as below
Sector | Separation (nm) | Separation (Min.) | Or | Separation (nm) | Separation (Min.) |
EKDK_E_CTR | 30nm | 6 | Or | 40* | 8* |
EKDK_D_CTR | 30nm | 6 | Or | 40* | 8* |
ESMM_K | -- | 10 | Or | 30* | 6* |
Above table depend on ERNOV. Use MDI=10 for ERNOV unless conditions renders impossible
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
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.
Sector | Separation (nm) | Separation (Min.) |
EKDK_B_CTR | 15nm | 3 |
EDWW_M | 25*/** | |
ESMM_L | -- | 10 |
*Ask Muritz to start stacking to FL270 if 25nm cannot be maintained.
*ensure Muritz employ minimum speed
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.
Sector | Separation (nm) | Pre-coordinated to minimum | |
Peak STAR | 10nm | 7.5 | |
Other STAR on the side | Complete STOP | 6 | |
STARs on other side | -- | 6min EAT, given as needed from holdings |
*15 min with that separation you can relieve almost 8 aircraft from a holding
Controller abbreviated procedures
As controllers expect following to be issued by EKDK_FMP
Low traffic load
All Sectors: Standard separation 10nm, min. 5nm only with verbal coordination
Medium traffic load
Depending on amount of aircrafts in the TMA.
If less than 10 aircraft in TMA expect following
Sector | Separation (nm) | Separation (Min.) | Or | Separation (nm) | Separation (Min.) |
EKDK_E_CTR | 20nm | 4 | Or | 25* | 5* |
EKDK_D_CTR | 20nm | 4 | Or | 25* | 5* |
EKDK_B_CTR | 15nm | 3 | Or | 30* | 6* |
*In case of high load on ESMM sectors.
If 10 aircraft or more in TMA
Sector | Separation (nm) | Separation (Min.) | Or | Separation (nm) | Separation (Min.) |
EKDK_E_CTR | 30nm | 6 | Or | 40* | 8* |
EKDK_D_CTR | 30nm | 6 | Or | 40* | 8* |
EKDK_B_CTR | 15nm | 3 | Or | 30* | 6* |
*In case of high load on ESMM sector
At all times shall you establish holdings in order to accommodate the required separation
Peak traffic load
Sector | Separation (nm) | Separation (Min.) | Or | Separation (nm) | Separation (Min.) |
EKDK_E_CTR | 30nm | 6 | Or | 40* | 8* |
EKDK_D_CTR | 30nm | 6 | Or | 40* | 8* |
ESMM_K | -- | 10 | Or | 30* | 6* |
*In case of high load on ESMM sector
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?
- 7.5-10nm separation. less than 7.5nm muts be coordinated. 7.5 and above is PRE-COORDINATED by FMP.
- another STAR on your side (East/West) is the subject?
- Stop all approaches. hold indefinately
- another STAR on opposite side (East/West) is the subject?
- EAT as assigned by EKDK_FMP. Keep a look out.
