ATS.TR.300 Application

PROVISION OF FLIGHT INFORMATION SERVICE TO AIRCRAFT OTHERWISE KNOWN TO AIR TRAFFIC SERVICES In the context of flight information service, the expression ‘otherwise known to the relevant air traffic service unit’ transposed from the Standard in Section 4.1 of ICAO Annex 11, covers the cases when the aircraft is operating within uncontrolled airspace, where there are no requirements for the submission of a flight plan or for a continuous air-ground two-way communication with the air traffic services unit in charge of providing services in that portion of airspace. Therefore, the expression may be interpreted as traffic, the current flight details and intentions of which are known to the air traffic controllers/FIS officer/AFIS officer.

It is recognised that in certain circumstances an aircraft on final approach, landing, take-off and climb may require to receive without delay essential information other than that pertaining to the air traffic control service provision.

RECORDING AND TRANSMISSION OF INFORMATION ON THE PROGRESS OF FLIGHTS Information on the actual progress of flights, including those of heavy or medium unmanned free balloons, under neither air traffic control service nor air traffic advisory service should be:

(a)recorded by the air traffic services unit serving the FIR within which the aircraft is flying in such a manner that it is available for reference and in case it is requested for alerting service and search and rescue action; and

(b)transmitted by the air traffic services unit receiving the information to other air traffic services units concerned, when so required for the purposes of the coordination between air traffic services units providing flight information service in adjacent FIRs in respect of IFR and VFR flights (see points (a) and (b) of GM2 ATS.TR.300(c)(2)).

INFORMATION EXCHANGE IN CASE OF TERMINATION OF A CONTROLLED FLIGHT In the case where a flight ceases to be operated as a controlled flight, i.e. by leaving controlled airspace or by cancelling its IFR flight and proceeding on VFR in airspace where VFR flights are not controlled, the air traffic control unit concerned should ensure that appropriate information on the flight is forwarded to air traffic services unit(s) responsible for the provision of flight information and alerting services for the remaining portion of the flight, in order to ensure that such services will be provided to the aircraft.

COORDINATION IN RESPECT OF THE PROVISION OF FLIGHT INFORMATION SERVICE AND ALERTING SERVICE

(a)Coordination between air traffic services units providing flight information service in adjacent FIRs should be effected in respect of IFR and VFR flights, in order to ensure continued flight information service to such aircraft in specified areas or along specified routes. Such coordination should be effected in accordance with an agreement between the air traffic services units concerned.

(b)The coordination of flights effected in accordance with point (a) should include transmission of the following information on the flight concerned:

(1)appropriate items of the current flight plan; and

(2)the time at which last contact was made with the aircraft concerned.

(c)This information should be forwarded to the air traffic services unit in charge of the next FIR in which the aircraft will operate prior to the aircraft entering such FIR.

(d)In order to assist in the identification of strayed or unidentified aircraft and thereby eliminate or reduce the need for interception, flight plan and flight progress information for flights along specified routes or portions of routes in close proximity to FIR boundaries should also be provided to the air traffic services units in charge of the FIRs adjacent to such routes or portions of routes.

(e)In circumstances where an aircraft has declared minimum fuel or is experiencing an emergency or in any other situation wherein the safety of the aircraft is not assured, the type of emergency and/or the circumstances experienced by the aircraft should be reported by the transferring unit to the accepting control unit and any other air traffic services unit that may be concerned with the flight and to the associated rescue coordination centres, if necessary.
