ENR 1.9  AIR TRAFFIC FLOW MANAGEMENT (ATFM)

1.9.1  Air Traffic Flow Management structure, service area, service provided, location of unit and hours of operation

1.9.1.1 Responsible service

The overall authority for the provision of Air Traffic Flow Management in the BRATISLAVA FIR/UIR is delegated to EUROCONTROL NMOC (Network Manager Operation Centre).

1.9.1.2 Service provided

NMOC is responsible for ensuring that:

  1. traffic flows correspond to the stated capacity of the sectors through which they pass,

  2. ATFM measures when necessary are applied in an equitable manner and in such a way as to reduce as far as possible the penalties to aircraft operators.

In order to do this the NMOC applies procedures which:

  1. are agreed internationally,

  2. are published in the corresponding NMOC documentation,

  3. have within the BRATISLAVA FIR the same status as procedures explicitly published in AIP S. R.

1.9.1.3 Responsibilities of the Air Traffic Services (ATS)

ATS shall provide a Flow Management Position (FMP) in each ACC/UAC to liaise between ATC, local aircraft operators and the NMOC.

In accordance with ICAO Doc 7030 assigned ATFM slot will be included as a part of the ATC clearance.

ATC units at aerodromes shall ensure that flights adhere to departure slots issued by the ATFM Service. In accordance with the provisions of the Regional Supplementary Procedures, Europe (ICAO Doc 7030), flights which do not adhere to their slot shall be denied start-up clearance. However ATS unit shall make all efforts to enable departing flights to comply with the slot and flights shall not be prevented from departing due to small taxiing delays.

1.9.1.4 Responsibilities of Aircraft Operators

Aircraft Operators shall inform themselves of and adhere to:

  1. general ATFM procedures including flight plan filing and message exchange requirements,

  2. strategic ATFM measures (e.g. RAD),

1.9.3  Procedures applicable for departing plan

1.9.3.1 Service responsible for provision of information on applied ATFM measures

Information on the planning and existing ATFM measures (AIM and ANM messages) can be obtained from all domestic AROs as well as from the Bratislava FMP.

1.9.3.2 Flight plan submission requirements
1.9.3.2.1 Operators/pilots of IFR-GAT flights and flights which a part of shall be performed in compliance with the IFR-GAT flights rules are requested to submit flight plans (FPL) for their flights at least 3 hours before the planned EOBT, should these flights be subject to ATFM measures. Before submitting a FPL, operators/pilots are obliged to familiarize themselves with the current ATFM situation in the airspace where the flight shall be performed. If, based on the available information, the operator/pilot is unable to establish whether the flight shall or shall not be the subject to ATFM measures, it is highly recommended to submit a FPL at least 3 hours before EOBT to avoid the likelihood of a considerable delay to such flight due to a SAM message.
1.9.3.2.2 If a FPL is submitted via CARO or ARO at local airports, the pilot is obliged to wait for the FPL processing until receiving either an ACK or REJ message. There is a possibility of arranging an alternative procedure with CARO/ARO staff in case the submitted FPL is rejected by IFPS and thus the necessity to send a new or corrected FPL shall arise.
1.9.3.2.3 The operator shall initiate by DLA or CHG message the notification about delay, when the departure of the aircraft is delayed more than 15 minutes.
1.9.3.3 Slot allocations
1.9.3.3.1 Operators/pilots will obtain departure slot, in case that their flight is subjected of ATFM measures, on the basis of the submitted FPL. NMOC will issue slot by ATFM message SAM (Slot Allocation Message) 2 hours before the last received EOBT.
1.9.3.3.2 A slot is assigned time (CTOT) and a tolerance of -5 to +10 minutes during which the aircraft shall take-off.
1.9.3.3.3 Operator/pilot is responsible to be ready for take-off at CTOT. A slot window of -5 to +10 minutes is primarily intended for use by ATC service to allow for airfield congestion problems.
1.9.3.3.4 Operators/pilots of flights which are unable to meet an allocated slot time, or when they request the change of their slot, are compulsory to comply with procedures published in EUROCONTROL Network Operational Handbook - IFPS Users Manual and ATFCM Users Manual.
1.9.3.3.5 When operators/pilots receive FLS message, they shall not request start-up clearence from ATC unit, until one of the following SAM, SRM, SLC, DES messages is received.
1.9.3.4  ATFM exemptions

STS indicator is used as information, that flight may require "special handling" for the reason explained in the next paragraph. STS indicator is for use by all parties, which may have to handle the flight.

To ensure the correct automatic processing of a FPL by the NMOC systems when ATFM exemptions are required, the following standardised abbreviations shall be used. These abbreviations are recognised by the NMOC systems:

  • - STS/ALTRV for a flight operated in accordance with an altitude reservation;

  • - STS/ATFMX for a flight approved for exemption from ATFM measures by the appropriate ATS authority;

  • - STS/FFR for a flight engaged in fire-fighting;

  • - STS/FLTCK for a flight check for calibration of navaids;

  • - STS/HAZMAT for a flight carrying hazardous material;

  • - STS/HEAD for a flight with ”Head of State” status;

  • - STS/HOSP for a medical flight specifically declared by the medical authorities;

  • - STS/HUM for a flight operating on a humanitarian mission;

  • - STS/MEDEVAC for a life critical medical emergency evacuation;

  • - STS/NONRVSM for a non-RVSM capable flight intending to operate in RVSM airspace;

  • - STS/SAR for a flight engaged in Search and Rescue missions;

  • - STS/STATE for a flight engaged in military, customs or police services.

REF:

  • EUROCONTROL Document - IFPS Users Manual;

  • EUROCONTROL Document - ATFCM Users Manual;

  • ICAO Doc 7030 Regional Supplementary Procedures (Europe).

Wrongful use of STS Indicator to avoid flow restrictions is regarded as a serious branch of ATFM procedures.

The STS indicators with STS/ATFMX, STS/FFR, STS/HEAD, STS/MEDEVAC and STS/SAR indicator shall be given an automatic exemption from ATFM measures, may not ask for it.

1.9.3.5 Route Availability Document (RAD)

The RAD is an ATFCM tool.

The RAD is only applicable to the IFR part of the Flight Plan.

REF:

  • ENR 1.10 Flight planning.

1.9.3.6 Date of Flight (DOF)
1.9.3.6.1 When the FPL is addressed to IFPS the date of flight (DOF) shall be given in field 18 of the FPL, in a six-figure format (YYMMDD, where YY equals the year, MM equals the month and DD equals the day). The DOF shall be introduced as a last item in the field 18 of FPL.

REF:

  • EUROCONTROL Document - IFPS Users Manual;

  • ICAO Doc 4444 Procedures for Air Navigation Services – Air Traffic Management.

1.9.3.7 En-route STAY indicator
1.9.3.7.1 STAY indicator enables to associate the time delays with certain special en-route activities such as training flights, air-to-air refuelling, photographic missions, etc. To indicate the time spent on the route of the flight in the area (STAY area) where special activities are planned a STAY indicator shall be inserted in field 15 of the FPL between the entry and exit point to/from the STAY area.

Example: MCT STAY1/0100 POL ...

The entry and exit points to/from STAY area may be the same or different.

Example: MCT STAY1/0030 MCT ...
MCT STAY1/0100 POL ...

STAY indicator can be duplicated on the route of a flight, then a sequence number shall be attached to each STAY indicator, a maximum value of 9.

Example: TNT STAY1/0030 TNT UP6 MCT STAY2/0030 MCT ...

The time spent in the STAY area by special activities shall be indicated in hours and minutes. It shall be possible to indicate changes to the flight rules (IFR/VFR) or type of flight (GAT/OAT) on the point of entry or exit point to/from STAY area.

Example: ... SHA VFR STAY1/0100 DCS/N0442F280 IFR ...

To indicate the reason for STAY indicator in field 15 of the FPL, a free text STAYINFO shall be inserted in field 18 of the FPL.

Example: Field 15 ... SHA STAY1/0030 SHA ...
Field 18 ... STAYINFO1/CALIBRATION OF SHA VOR ...

The sequence number in field 18 of the FPL shall be identical with the number attached to the corresponding to the field 15 of the FPL.

Requirements for usage of STAY indicator:

  1. shall only be used for en-route special activities;

  2. shall only be used for those flights that are completely the IFPS Zone;

  3. the time given in the STAY indicator shall be less than the total estimated elapsed time of the flight (EET);

  4. shall only be available for use in messages with title FPL, CHG or AFP;

  5. shall not be used in RPL.

It shall be possible to indicate the reason for the STAY in the flight plan.
