b) 1 2 10 6 in any period of 30 seconds for an MLS azimuth intended to be used for the full range of Category III operations (equivalent to 4 000 hours mean time between outages). 3.11.5.2.4.4 Recommendation The probability of not losing the radiated guidance signal should exceed in any period of seconds for an M S a imuth intended to be used for Category I operations (e uivalent to hours mean time between outages) Note uidance material on integrity and continuity of service is given in Attachment 3.11.5.2.5 round e uipment accuracy 3.11.5.2.5.1 The ground equipment contribution to the mean course error shall not exceed an error equivalent to plus or minus 3 m (10 ft) at the MLS approach reference datum. 3.11.5.2.5.2 Recommendation The ground e uipment contribution to the CMN at the reference datum should not exceed m ( ft) or degree whichever is less on a per cent probability basis Note This is the e uipment error and does not include any propagation effects Note uidance on the measurement of this parameter can be found in Attachment 3.11.5.2.6 Siting Note It is not intended to restrict the installation of M S when it is not possible to site the a imuth ground e uipment on the extension of the runway centre line Note uidance material on critical and sensitive areas for a imuth antennas is provided in Attachment 3.11.5.2.6.1 Normally, the approach azimuth ground equipment antenna shall be located on the extension of the runway centre line beyond the stop end and shall be adjusted so that the vertical plane containing the zero degree course line will contain the MLS approach reference datum. Siting of the antenna shall be consistent with safe obstacle clearance SARPs in Annex 14. 3.11.5.2.6.2 The back azimuth ground equipment antenna shall normally be located on the extension of the runway centre line at the threshold end, and the antenna shall be adjusted so that the vertical plane containing the zero degree course line will contain the back azimuth reference datum. 3.11.5.3 Elevation guidance e uipment 3.11.5.3.1 Scanning beam characteristics The elevation ground equipment antenna shall produce a fan-shaped beam that is narrow in the vertical plane, broad in the horizontal plane and which is scanned vertically between the limits of the proportional guidance sector. 3.11.5.3.1.1 Coordinate system Approach elevation guidance information shall be radiated in conical coordinates. 2007/70/II. szám Annex 10 — Aeronautical Communications Volume I 23/11/06 3.11.5.3.1.2 Antenna beamwidth The antenna beamwidth shall not exceed 2.5 degrees. 3.11.5.3.1.3 Scanning beam shape The minus 10-dB points on the beam envelope shall be displayed from the centre line by at least 0.76 beamwidth but not more than 0.96 beamwidth. Note The beam shape described applies on boresight in a multipath free environment using a suitable filter Information on beam shape and side lobes is provided in Attachment and 3.11.5.3.2 Coverage Note Diagrams illustrating the coverage re uirements specified herein are contained in Attachment Figure A 3.11.5.3.2.1 Approach elevation The approach elevation ground equipment shall provide proportional guidance information in at least the following volume of space. 3.11.5.3.2.1.1 Approach region
