b) 10 per cent of the nominal value for Facility Performance Category III. 3.1.3.7.3 Recommendation For Facility Performance Category II I S displacement sensitivity should be adjusted and maintained within the limits of plus or minus per cent where practicable Note The figures given in and are based upon a nominal sector width of m ( ft) at the appropriate point i e I S Point on runway codes and and the I S reference datum on other runways Note uidance material on the alignment and displacement sensitivity of locali ers using two radio fre uency carriers is given in of Attachment C Note uidance material on measurement of locali er displacement sensitivity is given in of Attachment C 3.1.3.7.4 The increase of DDM shall be substantially linear with respect to angular displacement from the front course line (where DDM is zero) up to an angle on either side of the front course line where the DDM is 0.180. From that angle to plus or minus 10 degrees, the DDM shall not be less than 0.180. From plus or minus 10 degrees to plus or minus 35 degrees, the DDM shall not be less than 0.155. Where coverage is required outside of the plus or minus 35 degrees sector, the DDM in the area of the coverage, except in the back course sector, shall not be less than 0.155. Note The linearity of change of DDM with respect to angular displacement is particularly important in the neighbourhood of the course line Note The above DDM in the degree sector is to be considered a minimum re uirement for the use of I S as a landing aid herever practicable a higher DDM e g is advantageous to assist high speed aircraft to execute large angle intercepts at operationally desirable distances provided that limits on modulation percentage given in are met Note herever practicable the locali er capture level of automatic flight control systems is to be set at or below DDM in order to prevent false locali er captures 3.1.3.8 oice 3.1.3.8.1 Facility Performance Categories I and II localizers may provide a ground-to-air radiotelephone communication channel to be operated simultaneously with the navigation and identification signals, provided that such operation shall not interfere in any way with the basic localizer function. 3.1.3.8.2 Category III localizers shall not provide such a channel, except where extreme care has been taken in the design and operation of the facility to ensure that there is no possibility of interference with the navigational guidance. 3.1.3.8.3 If the channel is provided, it shall conform with the following Standards: 3.1.3.8.3.1 The channel shall be on the same radio frequency carrier or carriers as used for the localizer function, and the radiation shall be horizontally polarized. Where two carriers are modulated with speech, the relative phases of the modulations on the two carriers shall be such as to avoid the occurrence of nulls within the coverage of the localizer. 3.1.3.8.3.2 The peak modulation depth of the carrier or carriers due to the radiotelephone communications shall not exceed 50 per cent but shall be adjusted so that: 2007/70/II. szám C a ter Annex 10 — Aeronautical Communications 3 11 23/11/06
