b) offset collocation 1) for those facilities used in terminal areas for approach purposes or other procedures where the highest position fixing accuracy of system capability is required, the separation of the VOR and DME antennas does not exceed 30 m (100 ft) except that, at Doppler VOR facilities, where DME service is provided by a separate facility, the antennas may be separated by more than 30 m (100 ft), but not in excess of 80 m (260 ft); 2) for purposes other than those indicated in 1), the separation of the VOR and DME antennas does not exceed 600 m (2 000 ft). 3.5.2.6.2 Association of DME with I S Note Attachment C gives guidance on the association of DME with I S 3.5.2.6.3 Association of DME with M S 3.5.2.6.3.1 Recommendation If a DME P is used to provide ranging information it should be sited as close as possible to the M S a imuth facility Note Attachment and Attachment C give guidance on siting of DME with M S This guidance sets forth in particular appropriate steps to be ta en to prevent different ero range indication if DME P associated with M S and DME N associated with I S serve the same runway 3.5.3 System characteristics 3.5.3.1 Performance 3.5.3.1.1 Range The system shall provide a means of measurement of slant range distance from an aircraft to a selected transponder to the limit of coverage prescribed by the operational requirements for the selected transponder. 2007/70/II. szám Annex 10 — Aeronautical Communications Volume I 23/11/06 3.5.3.1.2 Coverage 3.5.3.1.2.1 When associated with a VOR, DME/N coverage shall be at least that of the VOR to the extent practicable. 3.5.3.1.2.2 When associated with either an ILS or an MLS, DME/N coverage shall be at least that of the respective ILS or of the MLS azimuth angle guidance coverage sectors. 3.5.3.1.2.3 DME/P coverage shall be at least that provided by the MLS azimuth angle guidance coverage sectors. Note This is not intended to specify the operational range and coverage to which the system may be used spacing of facilities already installed may limit the range in certain areas 3.5.3.1.3 Accuracy 3.5.3.1.3.1 System accuracy The accuracy standards specified herein shall be met on a 95 per cent probability basis. Note The total system limits include errors from all causes such as those from airborne e uipment ground e uipment propagation and random pulse interference effects 3.5.3.1.3.2 DME N accuracy Recommendation At distances of from ero to m ( NM) from the transponder dependent upon the particular service application the total system error excluding reading error should be not greater than plus or minus m ( NM) plus per cent of distance measured 3.5.3.1.3.3 The total system error shall not exceed plus or minus 370 m (0.2 NM). Note This system accuracy is predicated upon the achievement of an airborne interrogator error contribution of not more than plus or minus m ( NM) Note In mixed DME N and DME P operations it is intended that the achieved accuracy be at least that in 3.5.3.1.3.4 DME P accuracy Note In the following two accuracy standards and are stated for the DME P to accommodate a variety of applications Note uidance on accuracy standards is given in Attachment C 3.5.3.1.3.4.1 Error components The path following error (PFE) shall be comprised of those frequency components of the DME/P error at the output of the interrogator which lie below 1.5 rad/s. The control motion noise (CMN) shall be comprised of those frequency components of the DME/P error at the output of the interrogator which lie between 0.5 rad/s and 10 rad/s. Note Specified error limits at a point are to be applied over a flight path that includes that point Information on the interpretation of DME P errors and the measurement of those errors over an interval appropriate for flight inspection is provided in Attachment C 3.5.3.1.3.4.2 Errors on the extended runway centre line shall not exceed the values given in Table B at the end of this chapter. 3.5.3.1.3.4.3 In the approach sector, away from the extended runway centre line, the allowable PFE for both standard 1 and standard 2 shall be permitted to increase linearly with angle up to plus or minus 40 degrees MLS azimuth angle where the permitted error is 1.5 times that on the extended runway centre line at the same distance. The allowable CMN shall not increase with angle. There shall be no degradation of either PFE or CMN with elevation angle. 2007/70/II. szám C a ter Annex 10 — Aeronautical Communications 23/11/06 3.5.3.2 Radio fre uencies and polari ation The system shall operate with vertical polarization in the frequency band 960 MHz to 1 215 MHz. The interrogation and reply frequencies shall be assigned with 1MHz spacing between channels. 3.5.3.3 Channelling 3.5.3.3.1 DME operating channels shall be formed by pairing interrogation and reply frequencies and by pulse coding on the paired frequencies. 3.5.3.3.2 Pulse coding DME/P channels shall have two different interrogation pulse codes as shown in the table in 3.5.4.4.1. One shall be used in the initial approach (IA) mode; the other shall be used in the final approach (FA) mode. 3.5.3.3.3 DME operating channels shall be chosen from Table A (located at the end of this chapter), of 352 channels in which the channel numbers, frequencies, and pulse codes are assigned. 3.5.3.3.4 Area channel assignment 3.5.3.3.4.1 In a particular area, the number of DME operating channels to be used shall be decided regionally. Note Standards and Recommended Practices on the utili ation of the DME fre uency band M are found in olume Chapter 3.5.3.3.4.2 The specific DME operating channels to be assigned in such a particular area shall also be decided regionally, taking into consideration the requirements for co-channel and adjacent channel protection. 3.5.3.3.4.3 Recommendation Coordination of regional DME channel assignments should be effected through ICA Note The above paragraphs permit the use of DME airborne interrogators having less than the total number of operating channels where so desired 3.5.3.3.5 Channel pairing When a DME transponder is intended to operate in association with a single VHF navigation facility in the 108 MHz to 117.95 MHz frequency band and/or an MLS angle facility in the 5 031.0 MHz to 5 090.7 MHz frequency band, the DME operating channel shall be paired with the VHF channel and/or MLS angle frequency as given in Table A. Note There may be instances when a DME will be paired with both the I S fre uency and an M S channel (see olume Chapter ) 3.5.3.4 Interrogation pulse repetition fre uency Note If the interrogator operates on more than one channel in one second the following specifications apply to the sum of interrogations on all channels 3.5.3.4.1 DME N The interrogator average pulse repetition frequency (PRF) shall not exceed 30 pairs of pulses per second, based on the assumption that at least 95 per cent of the time is occupied for tracking. 3.5.3.4.2 DME N If it is desired to decrease the time of search, the PRF may be increased during search but shall not exceed 150 pairs of pulses per second. 2007/70/II. szám Annex 10 — Aeronautical Communications Volume I 23/11/06 3.5.3.4.3 DME N Recommendation After pairs of pulses have been transmitted without ac uiring indication of distance the PRF should not exceed pairs of pulses per second thereafter until a change in operating channel is made or successful search is completed 3.5.3.4.4 DME N When, after a time period of 30 seconds, tracking has not been established, the pulse pair repetition frequency shall not exceed 30 pulse pairs per second thereafter. 3.5.3.4.5 DME P The interrogator pulse repetition frequency shall not exceed the following number of pulse pairs per second:
