s) Approach azimuth 62 to 62 13 000 6 800 0.020 High rate approach azimuth 42 to 42 9 000 4 800 0.020 Back azimuth 42 to 42 9 000 4 800 0.020 Approach elevation 1.5 to 29.5 3 500 3 350 0.020 Flare elevation 2 to 10 3 200 2 800 0.010 Note etween the end of the T scan and the beginning of the FR scan there is a pause time of no radiation of appropriate duration Additional information is provided in Attachment Note The maximum scan angles shown recogni e that the scan angle must exceed the proportional guidance sector limit by at least one half of the width of the detected scanning beam envelope (in e uivalent angle) to allow successful decoding 3.11.4.5.2 The tolerances on the ground equipment scanning beam velocity and the time separation between TO and FRO pulses corresponding to zero degrees shall be sufficient to satisfy the accuracy requirements specified in 3.11.4.9. 3.11.4.5.3 The TO and FRO scan transmissions shall be symmetrically disposed about the mid-scan point listed in each of Tables A-2 through A-5 of Appendix A. The mid-scan point and the centre of the time interval between the TO and FRO scan transmissions shall coincide with a tolerance of plus or minus 10 microseconds. 3.11.4.6 A imuth guidance functions 3.11.4.6.1 Each transmission of a guidance angle shall consist of a clockwise TO scan followed by a counterclockwise FRO scan as viewed from above the antenna. For approach azimuth functions, increasing angle values shall be in the direction of the TO scan. For the back azimuth functions, increasing angle values shall be in the direction of the FRO scan. Note A diagram illustrating the scanning conventions is provided in Attachment 3.11.4.6.2 Sector signals The transmission format of any azimuth function shall include time slots for airborne antenna selection, out-of-coverage indication, and test pulses as specified in Appendix A, Tables A-2 and A-3. The internal timing accuracy of the sector signals shall conform to the internal timing accuracy of the DPSK transitions specified in 3.11.4.3.4. 2007/70/II. szám Annex 10 — Aeronautical Communications Volume I 23/11/06 3.11.4.6.2.1 round e uipment identification The MLS providing services for a particular runway shall be identified by a four-character alphabetic designator starting with the letter M. This designator less the first letter shall be transmitted as a digital word as listed in Appendix A, Table A-7. Note It is not re uired that M S ground e uipment will transmit identification outside the angle guidance coverage sectors If M S channel identification is operationally re uired outside angle guidance coverage sectors it may be derived from associated omnidirectional DME (See and Attachment ) 3.11.4.6.2.1.1 The signal shall be transmitted on the data channel into the approach and back azimuth coverage regions. 3.11.4.6.2.1.2 The code bit in the time slot previously allocated for the alternate (Morse code) ground equipment identification following the azimuth preamble shall be fixed in the “ ERO” state. 3.11.4.6.2.2 Airborne antenna selection signal A signal for airborne antenna selection shall be transmitted as a “zero” DPSK signal lasting for a six-bit period. The signal shall be available throughout the coverage sector in which approach or back azimuth guidance is provided. Note The signal provides an opportunity for the selection of the most appropriate antenna in a multiple antenna airborne installation 3.11.4.6.2.3 A imuth out of coverage indication pulses Where out-of-coverage indication pulses are used, they shall be:
