c) clearance (fly right fly left) convention changes Note The proportional coverage limits are transmitted in basic data as specified in 3.11.4.7 Elevation guidance functions 3.11.4.7.1 Scanning conventions For the approach elevation function, increasing elevation guidance angles shall be in the upward direction. ero elevation angle shall coincide with a horizontal plane through the respective antenna phase centre. Each guidance angle transmission shall consist of a TO scan followed by a FRO scan. The TO scan shall be in the direction of increasing angle values. 3.11.4.7.2 Sector signal Provision for transmission of one out-of-coverage indication pulse shall be made in the format for the approach elevation function. Where an out-of-coverage indication pulse is used, it shall be: (1) greater than any guidance signal in the out-of-coverage indication sector and (2) at least 5 dB less than the guidance signals within the guidance sector. The elevation out-of-coverage indication timing shall be as shown in Appendix A, Table A-4. The duration of each pulse measured at the half amplitude points shall be at least 100 microseconds, and the rise and fall times shall be less than 10 microseconds. 3.11.4.7.2.1 If desired, it shall be permissible to sequentially transmit two pulses in each obstacle clearance indication time slot. Where pulse pairs are used, the duration of each pulse shall be at least 50 microseconds, and the rise and fall times shall be less than 10 microseconds. 3.11.4.8 Data functions Provision shall be made in the MLS signal format for the transmission of basic data and auxiliary data. Note round e uipment data coverage and monitoring re uirements are specified in 2007/70/II. szám Annex 10 — Aeronautical Communications Volume I 23/11/06 3.11.4.8.1 Data transmission Data shall be transmitted as specified in 3.11.4.4.3.1. 3.11.4.8.2 asic data structure and timing Basic data shall be encoded as 32-bit words consisting of a function preamble (12 bits) specified in 3.11.4.4, and data content as specified in Appendix A, Table A-7. The timing of the basic data words shall be as specified in Appendix A, Table A-6. The content, maximum interval between transmission of the same word and organization of the words shall be as specified in Appendix A, Table A-7. Data containing digital information shall be transmitted with the least significant bit first. The smallest binary number shall represent the lower absolute range limit with increments in binary steps to the upper absolute range limit specified in Appendix A, Table A-7. 3.11.4.8.2.1 asic data contents The data items specified in Appendix A, Table A-7 shall be defined as follows:
