Schedule 1
Assignment of Single Sideband Channels

(regs 33 and 34)

1.1.1. For the operational use of the channels concerned, an administration shall take into account the provisions of 27/19 of Appendix 27 of the International Telecommunications Union (ITU) Radio Regulations.

1.1.2. The use of an aeronautical mobile (R) frequency below 30 MHz for an international operation should be co-ordinated as specified in Appendix 27 of the ITU Radio Regulations as follows—

(a) 27/19 The International Civil Aviation Organisation (ICAO) co-ordinates radio communications of the aeronautical mobile (R) service with international aeronautical operations and this Organisation shall be consulted in all appropriate cases in the operational use of the frequencies in the Plan.

1.1.3. Where international operating requirements for HF communications cannot be satisfied by the Frequency Allotment Plan at Part 2 of Appendix 27 to the ITU Radio Regulations, an appropriate frequency may be assigned as specified in Appendix 27 by the application of the following provisions—

(a) 27/20 It is recognised that not all the sharing possibilities have been exhausted in the Allotment Plan contained in this Appendix. Therefore, in order to satisfy particular operational requirements which are not otherwise met by this Allotment Plan, administrations may assign frequencies from the aeronautical mobile (R) bands in areas other than those to which they are allotted in this Plan. However, the use of the frequencies so assigned must not reduce the protection to the same frequencies in the areas where they are allotted by the Plan below that determined by the application of the procedure defined in Part I, Section IIB of this Appendix;

(b) 27/21 When necessary to satisfy the needs of international air operations, administrations may adapt the allotment procedure for the assignment of aeronautical mobile (R) frequencies, which assignments shall then be the subject of prior agreement between administrations affected; and

(c) 27/22 The co-ordination described in No. 27/19 shall be effected where appropriate and desirable for the efficient utilisation of the frequencies in question, and especially when the procedures of No. 27/21 are unsatisfactory.

1.1.4. The use of classes of emission J7B and J9B shall be subject to the following provisions of Appendix 27—

(a) 27/12 For radiotelephone emissions the audio frequencies will be limited to between 300 and 2700 Hz and the occupied bandwidth of other authorised emissions will not exceed the upper limit of J3E emissions. In specifying these limits, however, no restriction in their extension is implied in so far as emissions other than J3E are concerned, provided that the limits of unwanted emissions are met (see Nos. 27/73 and 27/74);

(b) 27/14 On account of the possibility of interference, a given channel shall not be used in the same allotment area for radiotelephony and data transmissions; and

(c) 27/15 The use of channels derived from the frequencies indicated in 27/18 for the various classes of emissions other than J3E and H2B will be subject to special arrangements by the administrations concerned and affected in order to avoid harmful interference which may result from the simultaneous use of the same channel for several classes of emission.

1.2. Assignment of frequencies for aeronautical operational control communications

1.2.1. Worldwide frequencies for aeronautical operational control communications are required to enable aircraft operating agencies to meet the obligations contained in Civil Aviation (Operations of Aircraft) Regulations. Assignment of these frequencies shall be in accordance with the following provisions of Appendix 27—

(a) 27/9 A worldwide allotment area is one in which frequencies are allotted to provide long distance communications between an aeronautical station within that allotment area and aircraft operating anywhere in the world; and

(b) 27/217 The worldwide frequency allotments appearing in the tables at No. 27/213 and Nos. 27/218 to 27/231, except for carrier (reference) frequencies 3 023 kHz and 5 680 kHz, are reserved for assignment by administrations to stations operating under authority granted by the administration concerned for the purpose of serving one or more aircraft operating agencies. Such assignments are to provide communications between an appropriate aeronautical station and an aircraft station anywhere in the world for exercising control over regularity of flight and for safety of aircraft. Worldwide frequencies are not to be assigned by administrations for MWARA, RDARA and VOLMET purposes. Where the operational area of an aircraft lies wholly within a RDARA or sub-RDARA boundary, frequencies allotted to those RDARAs and sub-RDARAs shall be used.

Schedule 3
Deployment of VHF Frequencies and the Avoidance of Harmful Interference

(reg 41)

1.1 Provisions concerning the deployment of VHF frequencies and the avoidance of harmful interference.

1.1.1 The geographical separation between facilities operating on the same frequency shall, except where there is an operational requirement for the use of common frequencies for groups of facilities, be such that the protected service volume of one facility is separated from the protected service volume of another facility by a distance not less than that required to provide a desired to undesired signal ratio of 20 dB or by a separation distance not less than the sum of the distances to the associated radio horizon of each service volume, whichever is smaller.

1.1.2 For areas where frequency assignment congestion is severe or is anticipated to become severe, the geographical separation between facilities operating on the same frequency shall, except where there is an operational requirement for the use of common frequencies for groups of facilities, be such that the protected service volume of one facility is separated from the protected service volume of another facility by a distance not less than that required to provide a desired to undesired signal ratio of 14 dB or by a separation distance not less than the sum of the distances to the associated radio horizon of each service volume, whichever is smaller. This provision shall be implemented on the basis of a regional air navigation agreement.

1.1.3 The application of the minimum separation distance based on the sum of the radio horizon distance of each facility assumes that it is highly unlikely that two aircraft will be at the closest points between and at the maximum altitude of the protected service volume of each facility.

1.1.4 The distance to the radio horizon from a station in an aircraft is normally given by the formula—

D = Kh

where D = distance in nautical miles;

h = height of the aircraft station above earth;

K = (corresponding to an effective earth’s radius of 4/3 of the actual radius);

= 2.22 when h is expressed in metres; and

= 1.23 when h is expressed in feet.

1.1.5 In calculating the radio line-of-sight distance between a ground station and an aircraft station, the distance from the radio horizon of the aircraft station computed from Note 3 must be added to the distance from the radio horizon of the ground station. In calculating the latter, the same formula is employed, taking for h the height of the ground station transmitting antenna.

1.1.6 The geographical separation between facilities operating on adjacent channels shall be such that points at the edge of the protected service volume of each facility are separated by a distance sufficient to ensure operations free from harmful interference.

1.1.7 The protection height shall be a height above a specified datum associated with a particular facility, such that below it, harmful interference is improbable.

1.1.8 The protection height to be applied to functions or to specific facilities shall be determined regionally, taking into consideration the following factors—

(a) the nature of the service to be provided;

(b) the air traffic pattern involved;

(d) the availability of frequency channels in airborne equipment; and

(e) probable future developments.

1.1.9 Where the protected service volume is less than operationally desirable, separation between facilities operating on the same frequency shall not be less than that necessary to ensure that an aircraft at the upper edge of the operational service volume of one facility does not come above the radio horizon with respect to emissions belonging to the service of adjacent facilities.

1.1.10 The effect of 1.1.9 is to establish a geographical separation distance below which harmful interference is probable.

1.1.11 The geographical separation between VHF VOLMET stations shall be determined regionally and shall be such that operations free from harmful interference are secured throughout the protected service volume of each VOLMET station.

1.1.12 In the frequency band 117.975 – 137.000 MHz, the frequencies used for National Aeronautical Mobile Services, unless worldwide or regionally allotted to this specific purpose, shall be so deployed that no harmful interference is caused to facilities in the International Aeronautical Mobile Services.

1.1.13 The problem of inter-State interference shall be resolved by consultation between the States concerned.

1.1.14 The communication coverage provided by a VHF ground transmitter shall, in order to avoid harmful interference to other stations, be kept to the minimum consistent with the operational requirement for the function.
