ENR 1.10  FLIGHT PLANNING

1. PROCEDURES FOR THE SUBMISSION OF A FLIGHT PLAN

The EUR RVSM flight planning requirements for the completion of the ICAO Flight Plan Form and the Repetitive Flight Plan are contained in the ICAO EUR Regional Supplementary Procedures (Doc 7030).

Furthermore, the following requirement is in addition to the flight planning requirements contained in the ICAO EUR Regional Supplementary Procedures (Doc 7030):

In addition to military operations, operators of customs or police aircraft shall insert the letter M in Item 8 of the ICAO Flight Plan Form.

1.1 Submission of a flight plan

1.1.1 Submission of a flight plan shall normally be the duty of the pilot-in-command or of his deputy, except that for flights within the operation of an air transport enterprise, a flight plan may also be submitted by a representative of the operating agency.

1.1.2 A flight plan shall be submitted in accordance with ICAO Annex 2, paragraph 3.3.,1 prior to operating:

    1. any flight or portion thereof to be provided with ATC service for;
    2. any IFR flight outside controlled airspace or any VFR flight planned to operate at night, if leaving the vicinity of an aerodrome;
    3. any flight within or into designated areas, or along designated routes, when so required by the appropriate ATS authority to facilitate the provision of flight information, alerting and search and rescue services;
    4. any flight within or into designated areas, or along designated routes, when so required by the appropriate ATS authority to facilitate co-ordination with appropriate military units or with ATS units in adjacent States in order to avoid the possible need for interception for the purpose of identification;
    5. any flight across national borders;
    6. any flight outside controlled airspace operating within a 15 KM (8 NM) area from the borders with Belarus and Russia from ground level to FL095;
    7. any flight intending to be conducted in an aerodrome Traffic Information Zone (TIZ) and Traffic Information Area (TIA) during its operating hours.

1.1.3 Direct submission with IFPS (Integrated Initial Flight Plan Processing System)

    1. Flight plan originators concerned will generally be permitted to submit flight plans for IFR/GAT flights directly to the IFPS without the need to pass them through an ATS Reporting Office (ARO).
    2. Direct-filers take the full responsibility for compliance with all the relevant IFPS procedures, including complete addressing (e.g. within and outside the IFPS area, VFR part, Operational Air Traffic (OAT) part) of the message.

Detailed procedures are published in the IFPS Users Manual of the Network Operations Handbook.

b. Any Operational Reply Message (Acknowledgment (ACK), Manual (MAN), Rejection (REJ)) received at ARO Riga is kept available for the flight plan originators (aircraft operators, agencies concerned, pilots-in-command), who are responsible for collecting and responding to such messages at their discretion.

1.1.6 Submission of a flight plan during the flight (Air-filed flight plan (AFIL))

Flight plans may be filed during the flight, if warranted by certain circumstances (e.g. due to unforeseen weather changes, emergency situations). In this case the FIS will accept the flight plan data and will forward the flight plan to ARO Riga for further transmission to the competent units.

1.2 Procedures for the submission of a flight plan

1.2.1 Time of submission

The flight plan to or via flow- restricted areas shall be submitted at least 3 hours before EOBT.

Unless a repetitive flight plan has been submitted a flight plan shall be submitted at least 60 minutes prior to departure time or, if submitted during the flight, at a time which will ensure its receipt by the appropriate ATS unit at least 10 minutes before the aircraft is estimated to reach:

    1. the intended point of entry into a control area;
    2. the point of crossing an airway.

1.2.2 Place of submission

a. flight plans shall be submitted before departure to the ATS reporting office (ARO) Riga or during flight to a corresponding ATS unit ;

b. flight plans shall be submitted to ARO Riga in the following way:

2. REPETITIVE FLIGHT PLAN SYSTEM

2.1 General

The procedures concerning the use of Repetitive Flight Plans (RPL) conform to ICAO Doc 7030 , ICAO Doc 4444 and the EUROCONTROL Network Operations Handbook.

Aircraft Operators which make use of Repetitive Flight Plans (RPLs) are requested to ensure that RPL data for flights into, departing from or overflying the Riga FIR are submitted to the NM RPL Team.

RPLs shall be submitted in the IFPS RPL format as an attachment to an e-mail, addressed to

Email:rpl@eurocontrol.int


The IFPS Users Manual can be obtained from the EUROCONTROL Internet site:

URL:https://www.eurocontrol.int/publication/ifps-users-manual Further information can be obtained by contacting the RPL Supervisor at:

Email:rpl@eurocontrol.int

Tel: +32 27451957


2.2 Change of RPL

2.2.1 Permanent changes

Permanent changes to an approved RPL shall be submitted at least 7 working days prior to the operation of flights.

2.2.2 Single changes

A single change to an approved RPL for each individual flight shall be submitted no later than 60 minutes before the beginning of the flight, in the form of an ATC flight plan or change message.


2.3 Delay

When a specific flight is likely to encounter a delay of 15 minutes or more to the departure time stated in the RPL, the ATS unit serving the departure aerodrome within the Riga FIR shall be notified immediately.


2.4 ATS messages

For a flight operated on a RPL, no flight plan (FPL) message will be transmitted.

Departure (DEP), arrival (ARR), delay (DLA), change (CHG) and cancel (CNL) messages are transmitted to:

  • for IFR flights departing from the Riga FIR into IFPS zone, to IFPS only;
  • for IFR flights departing from the Riga FIR and exiting the IFPS zone, to IFPS and to ATS units outside the IFPS zone;
  • for VFR flights to corresponding ATS units in the Riga FIR and corresponding ATS units outside the Riga FIR.

3. CHANGES TO THE SUBMITTED FLIGHT PLAN

In the event of any change (+ or -) in an EOBT of more than 15 minutes for a flight for which a flight plan has been submitted, the flight plan shall be amended or a new flight plan shall be submitted after the old flight plan has been cancelled.

Note: Information submitted prior to departure regarding fuel endurance or total number of persons carried on board, if incorrect at the time of departure, constitutes a significant change to the flight plan and as such must be reported.

Whenever a flight, for which a flight plan has been submitted, is cancelled, the appropriate ATS unit shall be informed immediately.

3.1 Flight plan activation

If any flight departs from an uncontrolled Latvian aerodrome, airfield or heliport, after departure, the pilot shall activate the FPL (if submitted) and report the actual time of departure to the nearest ATS unit.

3.2 Closing a flight plan

3.2.1 A flight plan will be considered as closed after receipt of the arrival report.

3.2.2 An arrival report shall be made in person, by radiotelephony or via data link at the earliest possible moment after landing, to the appropriate ATS unit at the arrival aerodrome, by any flight for which a flight plan has been submitted covering the entire flight or the remaining portion of a flight to the destination aerodrome.

3.2.3 Submission of an arrival report is not required after landing at an aerodrome where ATS are provided on condition that radio communication or visual signals indicate that the landing has been observed.

3.2.4 When no ATS unit exists at the arrival aerodrome or operating site, the arrival report shall be made as soon as practicable after landing and by the quickest means available to the ARO Riga:

AFS: EVRAZPZX

Tel: +371 67300642, +371 67300645, +371 67783761

Fax:+371 67300644, +371 67220294

3.2.5 When a flight plan has been submitted which only covers a portion of a flight, other than the remaining portion of a flight to its destination, it shall be closed by submission of an appropriate report to the relevant ATS unit. This report cannot be considered as an arrival report.

3.2.6 When communication facilities at the arrival aerodrome or operating site are known to be inadequate and alternative arrangements for the handling of arrival reports on the ground are not available, the following action shall be taken. Immediately prior to landing the aircraft shall, if practicable, transmit to the appropriate ATS unit, a message comparable to an arrival report, where such a report is required. Normally, this transmission shall be made to the aeronautical station serving the ATS unit in charge of the FIR in which the aircraft is operated.

3.2.7 If it is expected that the arrival report will not reach the appropriate ATS unit within 30 minutes after the ETA, a notification shall be made in item 18 of the flight plan, providing information about the time when the arrival report may be expected (e.g RMK/EXPECT ARR REPORT 1520).

Arrival reports made by aircraft shall contain the following elements of information:

  1. aircraft identification;
  2. departure aerodrome or operating site;
  3. destination aerodrome or operating site (only in the case of a diversionary landing);
  4. arrival aerodrome or operating site;
  5. time of arrival.

4. FLIGHT PLAN MESSAGES ADDRESSING

4.1 Flights departing an aerodrome within the Riga FIR and remaining wholly within the IFPS Zone

4.1.1 Flight plan and associated messages need ONLY be addressed to the two IFPS units, as follows:

For AFTN - EUCHZMFP and EUCBZMFP

For SITA - BRUEP7X and PAREP7X

Note 1: All flight plans and associated messages must be addressed to both IFPUs

Note 2: Specific addresses for any VFR flights shall be added by the originator, preferably by using the Re-addressing function described in paragraph 4.4 below.

4.2 Flights entering or overflying the Riga FIR

4.2.1 For that portion of the flight within the Riga FIR, only the two IFPUs need to be addressed, as indicated in paragraph 4.1.1 above.

4.3 Flights departing an aerodrome within the Riga FIR and then exiting the IFPS Zone

4.3.1 For that portion of the flight within the Riga FIR, only the two IFPUs need to be addressed, as indicated in paragraph 4.1.1 above.

4.3.2 For any portion of the flight outside the IFPS zone, the flight plan message originator is responsible for addressing the flight plan and associated messages to all appropriate ATS units in accordance with ICAO Doc 4444 procedures. The procedure in paragraph 4.4 below, describes the preferred way of addressing as it ensures consistency between messages distributed within and outside the IFPS zone. This procedure will enable the IFPS to distribute a validated flight plan or associated message to any additional AFTN address which is included in the address line as described below.

4.4 Re-addressing function

4.4.1 Any additional addresses to be included should be placed after the originator information line and immediately before the open bracket which indicates the beginning of the message. An example of an AFTN message with such additional addresses is given below:

ZCZC BOC548 250925

FF EUCBZMFP EUCHZMFP

250920 EVRAZPZX

AD ADDRESS1 ADDRESS2 ADDRESS3 ADDRESS4 ADDRESS5 ADDRESS6 ADDRESS7

AD ADDRESS8

(FPL-BTI683-IS

-B735/M-SRYW/S

-EVRA1430

-……….

-………

The following rules apply:

  1. The extra address lines must begin with the keyword AD to distinguish them from other comment lines which may be present.
  2. The extra address lines must be consecutive (no other comment lines between them), and they must be immediately before the line containing the open bracket.
  3. There must be no more than 7 additional addresses per line, and each must be of 8 characters.

5. IFPS VALIDATION SYSTEM (IFPUV)

5.1 Flight plan originators wishing to test FPLs with the IFPUV, prior to their submission to the operational IFPS, may submit them via either AFTN or SITA to one of the following addresses:

AFTN: EUCHZMFV

SITA: BRUEY7X

5.2 Test flight plans may be submitted with a DATE OF FLIGHT (DOF) up to 120 hours (5 days) in advance by means of DOF/ in Item 18, in the format DOF/yymmdd where “yy” is the year indicator, “mm” is the month and “dd” is the day. The system will respond to the flight plan submission by means of a Reply Message in the form of either an Acknowledgement (ACK) which indicates that if the FPL is submitted to IFPS, the FPL would pass automatic processing or a Rejection (REJ) which indicates a failure. In the case of REJ the Reply Message will contain a system generated indication of the reason for failure. The IFPUV does not generate Manual (MAN) messages.

5.3 Every Reply Message from the IFPUV contains the phrase “This message has been sent by a test system and must not be used operationally”. This message is added to ensure that there is no confusion between submissions to the test system and those to the operational IFPS.

5.4 The IFPUV is not connected to the operational IFPS and test messages are neither distributed nor stored in the system. Since FPLs are not stored in the IFPUV, flight plan associated messages (i.e. CHG, DLA, CNL, RQP, etc.) are rejected by the IFPUV with the message: “ERROR: no existing filed flight plan matches this message”.
