g) a reduction of DDM to less than 0.175 within the specified coverage below the glide path sector. Note The value of ș from hori ontal is intended to ensure ade uate obstacle clearance This value was derived from other parameters of the glide path and monitor specification Since the measuring accuracy to four significant figures is not intended the value of ș may be used as a monitor limit for this purpose uidance on obstacle clearance criteria is given in the PANS PS (Doc ) 2007/70/II. szám Annex 10 — Aeronautical Communications Volume I 23/11/06 3 20 Note Subparagraphs f) and g) are not intended to establish a re uirement for a separate monitor to protect against deviation of the lower limits of the half sector below ș from hori ontal Note At glide path facilities where the selected nominal angular displacement sensitivity corresponds to an angle below the I S glide path which is close to or at the maximum limits specified in it may be necessary to adjust the monitor operating limits to protect against sector deviations below ș from hori ontal Note uidance material relating to the condition described in g) appears in Attachment C 3.1.5.7.2 Recommendation Monitoring of the I S glide path characteristics to smaller tolerances should be arranged in those cases where operational penalties would otherwise exist 3.1.5.7.3 The total period of radiation, including period(s) of zero radiation, outside the performance limits specified in 3.1.5.7.1 a), b), c), d), e) and f) shall be as short as practicable, consistent with the need for avoiding interruptions of the navigation service provided by the ILS glide path. 3.1.5.7.3.1 The total period referred to under 3.1.5.7.3 shall not exceed under any circumstances: 6 seconds for Category I — ILS glide paths; 2 seconds for Categories II and III — ILS glide paths. Note The total time periods specified are never to be exceeded limits and are intended to protect aircraft in the final stages of approach against prolonged or repeated periods of I S glide path guidance outside the monitor limits For this reason they include not only the initial period of outside tolerance operation but also the total of any or all periods of outside tolerance radiation including periods of ero radiation which might occur during action to restore service for example in the course of consecutive monitor functioning and conse uent changeovers to glide path e uipments or elements thereof Note From an operational point of view the intention is that no guidance outside the monitor limits be radiated after the time periods given and that no further attempts be made to restore service until a period in the order of seconds has elapsed 3.1.5.7.3.2 Recommendation here practicable the total period specified under for Categories II and III I S glide paths should not exceed second 3.1.5.7.4 Design and operation of the monitor system shall be consistent with the requirement that radiation shall cease and a warning shall be provided at the designated remote control points in the event of failure of the monitor system itself. Note uidance material on the design and operation of monitor systems is given in of Attachment C 3.1.5.8 Integrity and continuity of service re uirements 3.1.5.8.1 The probability of not radiating false guidance signals shall not be less than 1 0.5 10 9 in any one landing for Facility Performance Categories II and III glide paths. 3.1.5.8.2 Recommendation The probability of not radiating false guidance signals should not be less than in any one landing for Facility Performance Category I glide paths 3.1.5.8.3 The probability of not losing the radiated guidance signal shall be greater than 1 2 10 6 in any period of 15 seconds for Facility Performance Categories II and III glide paths (equivalent to 2 000 hours mean time between outages). 2007/70/II. szám C a ter Annex 10 — Aeronautical Communications 3 21 23/11/06 3.1.5.8.4 Recommendation The probability of not losing the radiated guidance signal should exceed in any period of seconds for Facility Performance Category I glide paths (e uivalent to hours mean time between outages) Note uidance material on integrity and continuity of service is given in of Attachment C 3.1.6 Localizer and glide path frequency pairing 3.1.6.1 The pairing of the runway localizer and glide path transmitter frequencies of an instrument landing system shall be taken from the following list in accordance with the provisions of Volume V, Chapter 4, 4.2: ocali er lide path (M ) (M ) 108.1 334.7 108.15 334.55 108.3 334.1 108.35 333.95 108.5 329.9 108.55 329.75 108.7 330.5 108.75 330.35 108.9 329.3 108.95 329.15 109.1 331.4 109.15 331.25 109.3 332.0 109.35 331.85 109.5 332.6 109.55 332.45 109.7 333.2 109.75 333.05 109.9 333.8 109.95 333.65 110.1 334.4 110.15 334.25 110.3 335.0 110.35 334.85 110.5 329.6 110.55 329.45 110.7 330.2 110.75 330.05 110.9 330.8 110.95 330.65 111.1 331.7 111.15 331.55 111.3 332.3 111.35 332.15 111.5 332.9 111.55 332.75 111.7 333.5 111.75 333.35 111.9 331.1 111.95 330.95 2007/70/II. szám Annex 10 — Aeronautical Communications Volume I 23/11/06 3 22 3.1.6.1.1 In those regions where the requirements for runway localizer and glide path transmitter frequencies of an instrument landing system do not justify more than 20 pairs, they shall be selected sequentially, as required, from the following list: Se uence number ocali er (M ) lide path (M ) 110.3 335.0 109.9 333.8 109.5 332.6 110.1 334.4 109.7 333.2 109.3 332.0 109.1 331.4 110.9 330.8 110.7 330.2 110.5 329.6 108.1 334.7 108.3 334.1 108.5 329.9 108.7 330.5 108.9 329.3 111.1 331.7 111.3 332.3 111.5 332.9 111.7 333.5 111.9 331.1 3.1.6.2 Where existing ILS localizers meeting national requirements are operating on frequencies ending in even tenths of a megahertz, they shall be reassigned frequencies, conforming with 3.1.6.1 or 3.1.6.1.1 as soon as practicable and may continue operating on their present assignments only until this reassignment can be effected. 3.1.6.3 Existing ILS localizers in the international service operating on frequencies ending in odd tenths of a megahertz shall not be assigned new frequencies ending in odd tenths plus one twentieth of a megahertz except where, by regional agreement, general use may be made of any of the channels listed in 3.1.6.1 (see Volume V, Chapter 4, 4.2). 3.1.7 VHF marker beacons 3.1.7.1 eneral
