ENR 1.10 FLIGHT PLANNING

1 FLIGHT PLANS (SERA.4001 AND NETWORK OPERATIONS HANDBOOK - IFPS USERS MANUAL)

Failure to comply with the following provisions may cause serious disruption in the air traffic services and may incur great expense in carrying out unnecessary search and rescue operations.

Information relative to an intended flight or portion of a flight, to be provided to air traffic services units, shall be in the form of a flight plan.

A flight plan shall contain information in accordance with the flight plan form and the instructions for the completions of the flight plan form as stated in paragraph 3.

the term aerodrome, when used in the flight plan, also covers sites other than aerodromes which may be used by certain types of aircraft, e.g. helicopters or balloons.
the term flight plan is used in the following paragraphs to denote the filed flight plan and update messages.
all information inserted into a flight plan may be used by LVNL for internal accident and incident investigation following the LVNL safety management system (Regulation (EU) 2017/373).
1.1 Submission of a flight plan (SERA.4001)
1.1.1 Requirements to submit a flight plan

A flight plan shall be submitted prior to operating:

  1. any flight or portion thereof to be provided with air traffic control service;
  2. any IFR flight;
  3. any flight or portion thereof operating in the North Sea area Amsterdam and North Sea area V (see ENR 2.2 paragraph 3 and chart ENR 6-3.1);
  4. any VFR flight operated in airspace class A, under special conditions (see ENR 1.2 paragraph 3.2).
  5. any flight across the Amsterdam FIR boundary, unless VFR to or from a Schengen country;
  6. any flight planned to operate at night, if leaving the vicinity of an aerodrome.

A flight plan can be transmitted during flight by radio if the flight plan covers only part of the flight. This does not apply to flights of which parts are executed:

  1. within the Schiphol CTR;
  2. in controlled airspace class A;
  3. in controlled airspace class B, except if the flight is carried out with a glider;
  4. in controlled airspace class C, above FL 195.
1.1.2 Procedures for the submission of a flight plan (ICAO Doc 4444, Appendix 2 and Network Operations Handbook - IFPS Users Manual)
1.1.2.1 Operational air traffic (OAT) / general air traffic (GAT)

An OAT route section is used to denote any portion of the route of a flight which is operating in accordance with military air traffic services procedures and which as a result does not require systematic addressing to civilian ATS units. IFPS uses the indicators OAT and GAT to indicate, in the route field of item 15, a change from GAT to OAT or vice versa.

1.1.2.2 Time of submission

(ICAO) flight plans shall be submitted at least 60 minutes prior to departure, except when air traffic flow management (ATFCM) regulations are in force along the route to be flown; in that case flight plans shall be submitted to the IFPS units at least 3 hours before estimated off-block time (EOBT). A flight plan should not be submitted earlier than 5 days (120 HR) before EOBT.

when the flight plan for a controlled flight only covers part of the flight and will be transmitted by radio during flight to the appropriate air traffic services unit, it shall be done in good time, so that this flight plan has been received at least 10 minutes before the expected time of entering the relevant control areas.
1.1.2.3 Place of submission
1.1.2.3.1 IFR or IFR/VFR flight plan

Holders of an air operator certificate (AOC) shall file their GAT IFR or IFR/VFR flight plan with IFPS using their own AFTN or SITA access point. Flight plans can also be filed via the internet using the Amsterdam Integrated Briefing system (AIB) (see GEN 3.1 paragraph 3.10.3).
If those means are not available, a flight plan may be communicated to the ARO serving the aerodrome of departure (see paragraph 1.1.2.4), using a phone. AFTN or SITA shall not be used by other parties for filing flight plans, these flight plans or flight plan related messages will be rejected.

IFPS addresses IFR flight plans. In case of a IFR/VFR flight plan, IFPS addresses only the IFR part of the flight plan automatically to the ATC units concerned in the IFPS zone. In case of a OAT/GAT flight plan, IFPS addresses only the GAT part of the flight plan automatically to the ATC units concerned in the IFPS zone.

The message originator is always responsible for ensuring the addressing of all appropriate messages to those ATS addresses concerned with VFR or OAT route portions and the addressing outside the IFPS zone. For more information see the IFPS users manual, section "Re-addressing".

Extra addresses may be included in extra address line(s) in any flight plan. Each extra address line must begin with the designator "AD". The IFPS will store the extra addresses and will automatically include them in all associated messages concerning the flight. Therefore, having sent the extra addresses in the flight plan, it is not necessary to repeat them in all associated messages (CHG, DLA, etc.).

Second stage flight plans for flights departing within the Amsterdam FIR shall be sent to the IFPS.

1.1.2.3.2 VFR flight plan

A VFR flight plan (including second stage flight plans) shall be submitted to the ARO serving the aerodrome of departure (see paragraph 1.1.2.4). Furthermore, VFR flight plans with DEST/ZZZZ shall also be adressed to EHAAZZXX. Flight plans can be filed via the internet using the Amsterdam Integrated Briefing (AIB) system (see GEN 3.1 paragraph 3.10.3). If AIB is not available, a flight plan may be communicated to the ARO serving the aerodrome of departure using a phone. AFTN or SITA shall not be used for submission of flight plans and or flight plan related messages (except messages from other AROs).
VFR flight plans will be addressed by the ARO.

The United Kingdom does not support the process for second stage flight plans. Regarding second stage flight plans of flights departing from within the United Kingdom filed at ARO Schiphol, ARO Schiphol is unable to address these flight plans to the subsequent ARO in the United Kingdom. The responsibility for ensuring that the second stage flight plans are correctly filed and addressed, and that supplementary information is kept up to date, lies with the pilot. ARO Schiphol is willing to assist pilots by fully addressing these flight plans (workload permitting) if the correct EET for FIR boundaries are inserted in item 18, however, ARO Schiphol cannot be held responsible for any failures that might occur.

1.1.2.3.3 Filing flight plan by telephone

If a flight plan or flight plan related message is filed by telephone, the phone number of the pilot is required. Failure to comply with this procedure may result in a rejection of the flight plan. Rejected flight plans or flight plan related messages are not sent to the ATC units concerned.

The pilot is responsible for checking with ARO Schiphol whether a flight plan or flight plan related message filed by telephone is accepted.

1.1.2.4 ARO service
  1. For all civil aerodromes and civil flights to uncontrolled operating sites in the Amsterdam FIR, the Amsterdam Flight Service Centre (FSC) has been designated as the responsible ARO. Contact information ARO Schiphol:

    Tel: +31 (0)20 406 2315

  2. For the military aerodromes BERGEN OP ZOOM/Woensdrecht, BREDA/Gilze-Rijen, DEN HELDER/De Kooy, EINDHOVEN/Eindhoven, LEEUWARDEN/Leeuwarden, UDEN/Volkel and military flights to uncontrolled operating sites in the Amsterdam FIR, the flight data and NOTAM office (MIL FDNO EHMC) at MILATCC Schiphol is the responsible ARO. Contact information MIL FDNO EHMC:

    Tel: +31 (0)20 406 2840

    Email: [email protected]

1.1.2.5 Acceptance of flight plans filed via an electronic system

Upon filing a flight plan the following operational reply messages (ORMs) are sent to the message originator and/or aircraft operator (AO) to indicate the processing status of a message:

  1. IFPS sends ACK, MAN, and REJ messages.
  2. ARO Schiphol accepts or rejects VFR flight plans.
if the flight plan is filed via the internet, using the Amsterdam Integrated Briefing (AIB) system, the status of the flight plan is shown in AIB.

If no ACK message is returned by IFPS or, in case of a VFR flight plan ARO Schiphol rejects the VFR flight plan, the flight plan is not sent to the concerned ATC units. This may result in significant delays.

1.1.2.6 Alerting service for VFR flight (SERA.10001)

Alerting service will be provided to flights for which a flight plan has been submitted. In order to facilitate provision of alerting service including search and rescue, insertion of the phone number of the pilot in the flight plan (item 19) is strongly advised.

For national VFR flights between uncontrolled aerodromes there is no requirement for submission of a flight plan (except as provided in paragraph 1.1.1). For such flights the pilot may request alerting service by submitting a flight notification (see paragraph 1.3), at the airport office of the departure aerodrome and the aerodrome of destination prior to departure.

The aerodrome of destination keeps watch over the reported flight and will initiate alerting action if the flight has not landed within 30 minutes after the estimated time of arrival.

This watch is only effective if every pilot adheres strictly to paragraph 1.4 "Changes to a flight plan" and paragraph 1.5 "Arrival report".

1.2 Contents and form of a flight plan (SERA.4005 and ICAO Doc 4444)
  1. ICAO flight plan forms (electronic or paper) are available at Please comply with the instructions for completing these forms.
  2. Flight plans concerning IFR flights along ATS routes need not include FIR boundary estimates. Inclusion of FIR boundary estimates is however required for off-route IFR flights.
  3. A flight plan for an international VFR flight shall include estimates for FIR boundaries.
1.3 Contents of a flight notification (see paragraph 1.1.2.6)
  1. Aircraft identification, type of aircraft.
  2. Departure aerodrome, expected time of departure.
  3. Destination aerodrome, expected time of arrival.
  4. Endurance.
  5. Persons on board.
  6. Pilot in command and phone number.
1.4 Changes to a flight plan or flight notification (SERA.4015 and Network Operations Handbook - IFPS Users Manual)

All changes to a flight plan shall be reported as soon as possible to the appropriate ATS unit, subject to the provisions below. All significant changes to a flight notification shall be reported as soon as possible to the aerodrome of destination, subject to the provisions below.

  1. In the event of a delay (see note) in departure of more than 15 minutes for IFR flights (30 minutes for VFR flights) for which a flight plan or a flight notification has been submitted, the flight plan or the flight notification shall be amended, or cancelled and resubmitted.
  2. Whenever a flight for which a flight plan has been submitted, is cancelled, the appropriate ATS unit shall be informed immediately. Whenever a flight for which a flight notification has been submitted, is cancelled, the aerodrome of destination shall be informed immediately.
  3. Changes to a current flight plan for a controlled flight during flight shall be reported or requested subject to the provisions in SERA.8020 (Adherence to flight plan).
  4. Certain key items within a flight plan cannot be modified by a CHG message within IFPS as they are used for message association. These non-changeable items are: ARCID, ADEP, ADES, EOBD. To change one of the above items it will be necessary to cancel the original flight plan and to refile a flight plan containing the corrected data. The replacement flight plan (RFP) procedure shall not be used for such changes; see (paragraph 1.7).
  5. To indicate a delay to a flight, a DLA or a CHG message may be used depending on the circumstances.
    • To amend the EOBT to a later time, a DLA shall be sent to IFPS. Please note that the IFPS does not accept:
      • A negative delay i.e. a new EOBT which is earlier than the existing EOBT in the flight plan. Should the EOBT of a flight need to be changed to an earlier time, that flight must be cancelled and re-filed with the earlier EOBT.
      • A new EOBT which is more than 20 hours in the future compared to existing EOBT in the flight plan.
      • A new EOBT which is in the past compared to the current IFPS system time at the moment the DLA or CHG message is processed plus 5 minutes.

      The existing EOBT of the flight is the original EOBT given in the flight plan including all the subsequent updates.

    • It is recommended to wait until the ACK for the CNL message has been received before sending the new flight plan.
  6. DLA or CHG messages should not be sent to IFPS to indicate a delay caused by the reception of a slot allocation message (SAM). ATS units concerned with the flight are also sent the SAM and therefore do not require the information.
if a delay in departure (or cancellation) is not properly reported, alerting or search and rescue action may be unnecessarily initiated, when the flight fails to arrive at the destination aerodrome within 30 minutes after its current ETA (NB: the current ETA is the ETA updated after departure).
1.5 Arrival report (Closing a flight plan, SERA.4020)

A report of arrival shall be made at the earliest possible moment after landing to the airport office of the arrival aerodrome by any flight for which a flight plan or flight notification has been submitted, except when the arrival has been acknowledged by the local ATC unit.

After landing at an aerodrome which is not the destination aerodrome (diversionary landing) the local ATC unit or the airport office at the arrival aerodrome shall be specifically informed accordingly. When a flight notification has been submitted, the pilot is, in addition to the paragraph above, also responsible for passing the arrival report to the destination aerodrome. In the absence of a local ATC unit or an airport office at the arrival aerodrome or operating site, the pilot shall inform the responsible ARO as soon as possible.

Arrival reports shall contain the following elements of information:

  • aircraft identification
  • departure aerodrome
  • destination aerodrome or operating site
  • time of arrival

In the case of diversion insert between "destination aerodrome" and "time of arrival":

  • arrival aerodrome.
1.6 Repetitive flight plans

LVNL and the EUROCONTROL network manager (NM) do not process repetitive flight plans (RPLs).

1.7 Replacement flight plans (RFP) (Network Operations Handbook - IFPS Users Manual)

When a flight plan (FPL) has been filed, and, in the pre-flight stage (i.e. within 4 hours of EOBT), an alternative routing is selected between the same aerodromes of departure and destination, the operator or pilot shall follow the present procedures ensuring that:

  1. the original flight plan is cancelled by submitting a CNL message using the DD priority indicator.
  2. the replacement flight plan1) shall contain amongst others the original identification (ACFT identification), the complete new route in item 15 of the flight plan and the indication RFP/Qn in item 18, where:
    • "RFP" signifies a replacement flight plan and;
    • "n" corresponds to the sequence number of flight plan replacement for that particular flight.
  1. It is recommended to wait until the ACK for the CNL message has been received before sending the replacement flight plan.

2 FLIGHT PLANNING

2.1 Adherence to airspace utilization rules and route availability
  • No flight plans shall be filed for routes deviating from the published ATS route structure, unless prior permission has been obtained from the Netherlands ATC authorities.
  • No flight plans shall be filed via the Amsterdam FIR/UIR deviating from the State restrictions defined within the Route Availability Document (RAD). This common European reference document contains all airspace utilisation rules and availability for the Amsterdam FIR/UIR and any reference to them shall be made via https://www.nm.eurocontrol.int/RAD/index.html.
2.1.1 Authorisation for incidental flights

Incidental flights of a specific character such as survey flights, scientific research flights etc. May be exempted from the restriction specified in paragraph 2.1. Requests for exemptions are available at the Operational Helpdesk:

2.2 Airspeed restriction (SERA.6001)

IFR flights below FL 100 in airspace classes D, E, F, G and VFR flights below FL 100 in airspace classes C, D, E, F, G shall not be operated in level cruising flight at an airspeed exceeding 250 KIAS, except where approved by the competent authority for aircraft types, which for technical or safety reasons, cannot maintain this speed.

2.3 Level assignment
2.3.1 Minimum flight levels

The minimum IFR flight level for:

  • pressurised ACFT overflying Amsterdam FIR is MNM FL 150/160.
  • flights crossing Schiphol TMA is MNM FL 100.
  • flights inbound AMSTERDAM/Schiphol airport is MNM FL 070 at the Schiphol TMA boundary.
2.3.2 Maximum cruising levels for short-range flights

IFPS checks the compliance of the filed route as provided in the Route Availability Document (RAD). In the RAD maximum cruising levels are listed in annex 2A. The RAD is available via the website https://www.nm.eurocontrol.int/RAD/index.html.

Due to the upper-lower structure in the Amsterdam FIR, FL 250 is not available as cruising level to overfly the Amsterdam FIR.

2.4 RVSM airspace

Except for operations within the EUR RVSM transition airspace, operators of non-RVSM approved aircraft shall flight plan to operate outside the EUR RVSM airspace.

2.5 Flight planning buffer zone (FBZ)

For some reserved/restricted areas, a FBZ is created (see ENR 5.1). The FBZ is the associated airspace which may be applied to a reserved/restricted area defining the lateral and vertical limits for the purpose of submitting a valid IFR FPL when such areas are active or planned to be active.

For the submission of a valid flight plan (for an aircraft not engaged in an activity contained in the reserved/restricted airspace) the FBZ together with the reserved/restricted area represent the totality of airspace to be avoided for flight planning purposes. The FBZ ensures that a planned flight path does not run through, or too close to, a restricted area. Based on that information IFPS will accept or decline a proposed flight plan.

  • Flight plans can be filed up to the boundary of the FBZ when active.
  • The route described in Item 15, shall consider the nominal track between two points according to the great circle shortest route.
  • Reserved/restricted airspace and the FBZ are notified when active as indicated in ENR 5.1.

3 INSTRUCTIONS FOR THE COMPLETION OF THE FLIGHT PLAN FORM

+Requirements of the appropriate ATS authority in the Amsterdam FIR.
++Difference from or addition to PANS-RAC-provisions.
xWhen so prescribed by the appropriate ATS authority.

The expression "appropriate ATS authority" relates to the relevant authority designated by the State responsible for providing air traffic services in the airspace concerned. The requirements of the appropriate ATS authority may differ from FIR to FIR along the route of the flight.

IFPS uses the indicators "OAT" and "GAT" to indicate a change from GAT to OAT or vice versa. The indicator shall be inserted after the appropriate significant point in the route.

the significant point must be published in AIP Netherlands.
Examples:N0400F280..........NTM
OAT TB6..........
This example shows a change from GAT to OAT at the point NTM.
N0400F280 ..........
NTM/N0300F250 OAT
TB6 ........
This example shows the same change as the previous example but together with a change of speed and flight level. IFPS always assumes that all flight plans begin GAT, unless it finds a change to GAT indicated later in the route. In this case it is assumed that everything prior to the change was OAT.
N0460F370 MC1
........... TB6 NTM GAT
UR110 DIK UA242.......
In this example IFPS, having found a change to GAT indicated at NTM, will assume that everything prior to NTM was OAT and therefore will only begin route extraction and therefore addressing from NTM onwards.
