ENR 1.10 FLIGHT PLANNING

(Restriction, limitation or advisory information)

1. REQUIREMENT FOR THE SUBMISSION OF A FLIGHT PLAN

1.1 i Operators of all flights within the Muscat FIR are required to submit a flight plan;

ii Operators of local flights, i.e., those which will remain within the Muscat TMA or Salalah CTR may satisfy the above requirements by notifying the appropriate ATSU of:

a) the aircraft call sign (and registration, if different);

b) the ETD and brief details of the intended flight;

c) the destination.

1.2 All Aircraft operators shall submit their Flight Plans in accordance with the ICAO format not more than 120 hours and at least 60 minutes prior to estimated offblocks time (EOBT) and / or entering the Muscat FIR.

Note: Oman does not use the Intermediate Stop procedure as detailed in ICAO Doc. 4444 – Section 11, paragraph 11.4.2.2.2.3

1.3 Flights inbound to or overflying Muscat FIR airspace with no flight plan (FPL) are subject to be held at the boundary or denied access to the airspace until FPL is received.

1.4 Time of submission

A flight plan shall be submitted at least 60 minutes prior to departure, taking into account the requirements for timely information to ATS units within the airspace along the proposed route to be flown, including requirements for early flight plan submission for Air Traffic Flow Management (ATFM) purposes.

Note: Due to automation within the Muscat ACC it is imperative that all operators operating within or overflying the MUSCAT FIR file delay messages of 30 min or more from the dep time given in the FPL. Failure to do so will result in the termination of flight plan data and a subsequent delay to the operation of that particular flight.

1.5 Place of submission

a) Flight plans shall be submitted via the Air Traffic Services Reporting Office (ARO) at the departure aerodrome.

b) All flight plans shall be submitted by AFTN or email

Note 1: All FPLs shall be submitted to the following addresses:

AFS: Refer to ENR 1.11 - Addressing of Flight Plan messages

Email:

Muscat: briefing@caa.gov.om

Salalah: SLL-AIS@caa.gov.om

Note 2: ARO will distribute the FPLs to all related FIRs, Destination and Alternate Aerodromes.

c) For VFR flights between uncontrolled aerodromes, operating along designated VFR routes in a TMA, a flight plan shall be submitted by email to the nearest ARO.

d) For domestic flights from an uncontrolled to a controlled aerodrome a flight plan shall be submitted by email to the ARO at the destination.

1.6 VFR flight plan for alerting service only

Alerting service is, in principle, provided to flights for which a flight plan has been submitted.

1.7 Contents and form of a flight plan

a) ICAO flight plan forms are available at AROs and airport offices at uncontrolled aerodromes. The instructions for completing those forms shall be complied with.

b) 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 and international VFR flights.

c) When a flight plan is submitted by telephone, teletype or telefax, the sequence of items of the flight plan-form shall be strictly followed.

1.8 Adherence to ATS route structure

No flight plans shall be filed for routes deviating from the published ATS route structure, unless prior permission has been obtained from the appropriate ATC authorities.

1.9 Authorization for special flights

Flights of a specific character such as survey flights, scientific research flights, etc., may be exempted from the restriction specified above.

Request for exemption shall be mailed so as to be received at least one week before the intended day of operation to:

Postal Address:
Civil Aviation Authority
P. O. Box 1
POSTAL CODE 111
MUSCAT
Sultanate of Oman

AFS Address: OOMSYAYX

Telefax: (968) 24 510122

1.10 Maximum cruising levels for short-range flights

It is generally recommended not to select levels above FL240 for flights up to a distance of 300 NM.

2. OPERATION OF REPETITIVE FLIGHT PLAN (RPL)

RPLs are not accepted and all operators are required to file a full flight plan in accordance with ENR 1.10.

3. CHANGES TO THE SUBMITTED FLIGHT PLAN

3.1 All changes to a flight plan submitted for an IFR flight or a controlled VFR flight and significant changes to a flight plan submitted for an uncontrolled VFR flight shall be reported as soon as possible to the appropriate ATS unit. In the event of a delay in departure of 30 minutes or more 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 plan has been canceled. It is imperative that standard ICAO CHG, DLA, CNL protocols are used.

Note 1: If a delay in departure of a controlled flight is not properly reported, the relevant flight plan data may no longer be readily available to the appropriate ATS unit when a clearance is ultimately requested, which will consequently result in extra delay for the flight.

Note 2: If a delay in departure (or cancellation) of an uncontrolled VFR flight 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.

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

3.3 Changes to a current flight plan for a controlled flight during flight shall be reported or requested, subject to the provisions in ICAO Annex 2, 3.6.2. (Adherence to flight plan). Significant changes to a flight plan for an uncontrolled VFR flight include changes in endurance or in the total number of persons on board and changes in time estimates of 3 minutes or more.

3.4 Arrival report (closing a flight plan)

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 has been submitted except when the arrival has been acknowledged by the local ATS unit. After landing at an aerodrome which is not the destination aerodrome (diversionary landing), the local ATS unit shall be specifically informed accordingly. In the absence of a local ATS unit at the aerodrome of diversionary landing, the pilot is responsible for passing the arrival report to the destination aerodrome.

Arrival reports shall contain the following elements of information:

a) aircraft identification

b) departure aerodrome

c) destination aerodrome

d) time of arrival

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

4. FLIGHT PLAN

4.1 Flight Plan Form

Make up the correct number of figures, where necessary, by insertion of zeros, e.g. 4620N 07805W (11 characters).

or, Bearing and distance from the nearest significant point, as follows:

The identification of the significant point followed by the bearing from the point in the form of 3 figures giving degrees magnetic, followed by the distance from the point in the form of 3 figures expressing nautical miles. In areas of high latitude where it is determined by the appropriate authority that reference to degrees magnetic is impractical, degrees true may be used. Make up the correct number of figures, where necessary, by insertion of zeros, e.g. a point of 180° magnetic at a distance of 40 nautical miles from VOR “DUB” should be expressed as DUB180040.

or, The first point of the route (name or LAT/ LONG) or the marker radio beacon, if the aircraft has not taken off from an aerodrome.

DEST/ Name and location of destination aerodrome, if ZZZZ is inserted in Item 16. For aerodromes not listed in the relevant Aeronautical Information Publication, indicate location in LAT/ LONG or bearing and distance from the nearest significant point, as described under DEP/ above.

DOF/ The date of flight departure in a six-figure format (YYMMDD, where YY equals the year, MM equals the month and DD equals the day).

REG/ The nationality or common mark and registration mark of the aircraft, if different from the aircraft identification in Item 7.

EET/ Significant points or FIR boundary designators and accumulated estimated elapsed times from take-off to such points or FIR boundaries, when so prescribed on the basis of regional air navigation agreements, or by the appropriate ATS authority.

Examples:
EET/CAP0745 XYZ0830
EET/EINN0204

SEL/ SELCAL Code, for aircraft so equipped.

TYP/ Type(s) of aircraft, preceded if necessary without a space by number(s) of aircraft and separated by one space, if ZZZZ is inserted in Item 9.

Example: TYP/2F15 5F5 3B2

CODE/ Aircraft address (expressed in the form of an alphanumerical code of six hexadecimal characters) when required by the appropriate ATS authority.

Example: “F00001” is the lowest aircraft address contained in the specific block administered by ICAO.

DLE/ En-route delay or holding, insert the significant point(s) on the route where a delay is planned to occur, followed by the length of delay using four figure time in hours and minutes (hhmm).

Example: DLE/MDG0030

OPR/ ICAO designator or name of the aircraft operating agency, if different from the aircraft identification in Item 7.

ORGN/ The originator’s 8 letter AFTN address or other appropriate contact details, in cases where the originator of the flight plan may not be readily identified, as required by the appropriate ATS authority.

Note) In some areas, flight plan reception centres may insert the ORGN/ identifier and originator’s AFTN address automatically.

PER/ Aircraft performance data, indicated by a single letter as specified in the Procedures for Air Navigation Services — Aircraft Operations (PANS-OPS, Doc 8168), Volume I — Flight Procedures, if so prescribed by the appropriate ATS authority.

ALTN/ Name of destination alternate aerodrome(s), if ZZZZ is inserted in Item 16. For aerodromes not listed in the relevant Aeronautical Information Publication, indicate location in LAT/ LONG or bearing and distance from the nearest significant point, as described in DEP/ above.

RALT/ ICAO four letter indicator(s) for En-route alternate(s), as specified in Doc 7910, Location Indicators, or name(s) of en-route alternate aerodrome(s), if no indicator is allocated. For aerodromes not listed in the relevant Aeronautical Information Publication, indicate location in LAT/LONG or bearing and distance from the nearest significant point, as described in DEP/ above.

TALT/ ICAO four letter indicator(s) for take-off alternate, as specified in Doc 7910, Location Indicators, or name of take-off alternate aerodrome, if no indicator is allocated. For aerodromes not listed in the relevant Aeronautical Information Publication, indicate location in LAT/LONG or bearing and distance from the nearest significant point, as described in DEP/ above.

RIF/ The route details to the revised destination aerodrome, followed by the ICAO four-letter location indicator of the aerodrome. The revised route is subject to reclearance in flight.

Examples:
RIF/DTA HEC KLAX
RIF/ESP G94 CLA YPPH

RMK/ Any other plain-language remarks when required by the appropriate ATS authority or deemed necessary.
