c) plus or minus 6 kHz or more away and 55 dB stronger. Note The above bearing error is exclusive of aircraft magnetic compass error 3 10 Reser ed 3 11 icro a e landing system S c aracteristics 3.11.1 Definitions Auxiliar data Data, transmitted in addition to basic data, that provide ground equipment siting information for use in refining airborne position calculations and other supplementary information. asic data Data transmitted by the ground equipment that are associated directly with the operation of the landing guidance system. eam centre The midpoint between the two minus 3-dB points on the leading and trailing edges of the scanning beam main lobe. eamwidt The width of the scanning beam main lobe measured at the minus 3-dB points and defined in angular units on the boresight, in the horizontal plane for the azimuth function and in the vertical plane for the elevation function. Clearance uidance sector The volume of airspace, inside the coverage sector, within which the azimuth guidance information provided is not proportional to the angular displacement of the aircraft, but is a constant left or right indication of which side the aircraft is with respect to the proportional guidance sector. Control motion noise (C ) That portion of the guidance signal error which causes control surface, wheel and column motion and could affect aircraft attitude angle during coupled flight, but does not cause aircraft displacement from the desired course and/or glide path. (See 3.5.) Coordinate s stem — conical A function is said to use conical coordinates when the decoded guidance angle varies as the minimum angle between the surface of a cone containing the receiver antenna, and a plane perpendicular to the axis of the cone and passing through its apex. The apex of the cone is at the antenna phase centre. For approach azimuth or back azimuth functions, the plane is the vertical plane containing the runway centre line. For elevation functions, the plane is horizontal. Coordinate s stem — lanar A function is said to use planar coordinates when the decoded guidance angle varies as the angle between the plane containing the receiver antenna and a reference plane. For azimuth functions, the reference plane is the vertical plane containing the runway centre line and the plane containing the receiver antenna is a vertical plane passing through the antenna phase centre. Covera e sector A volume of airspace within which service is provided by a particular function and in which the signal power density is equal to or greater than the specified minimum. 2007/70/II. szám Annex 10 — Aeronautical Communications Volume I 23/11/06 The distance measuring element of the MLS, where the “P” stands for precise distance measurement. The spectrum characteristics are those of DME/N. Function A particular service provided by the MLS, e.g. approach azimuth guidance, back azimuth guidance or basic data, etc. ean course error The mean value of the azimuth error along the runway extended centre line. ean lide at error The mean value of the elevation error along the glide path of an elevation function. inimum lide at The lowest angle of descent along the zero degree azimuth that is consistent with published approach procedures and obstacle clearance criteria. Note This is the lowest elevation angle which has been approved and promulgated for the instrument runway antenna oresi t The plane passing through the antenna phase centre perpendicular to the horizontal axis contained in the plane of the antenna array. Note In the a imuth case the boresight of the antenna and the ero degree a imuth are normally aligned owever the preferred designation in a technical context is boresight whereas the preferred designation in an operational context is ero degree a imuth (see definition below) a imut The locus of points in any horizontal plane where the decoded guidance angle is constant. a roac re erence datum A point at a specified height above the intersection of the runway centre line and the threshold. ac a imut re erence datum A point at a specified height above the runway centre line at the runway midpoint. datum oint The point on the runway centre line closest to the phase centre of the approach elevation antenna. elevation The locus of points in any vertical plane where the decoded guidance angle is constant. ero de ree a imut The MLS azimuth where the decoded guidance angle is zero degrees. ut o covera e indication si nal A signal radiated into areas outside the intended coverage sector where required to specifically prevent invalid removal of an airborne warning indication in the presence of misleading guidance information. at ollowin error ( F ) That portion of the guidance signal error which could cause aircraft displacement from the desired course and/or glide path. at ollowin noise ( F ) That portion of the guidance signal error which could cause aircraft displacement from the mean course line or mean glide path as appropriate. ro ortional uidance sector The volume of airspace within which the angular guidance information provided by a function is directly proportional to the angular displacement of the airborne antenna with respect to the zero angle reference. 3.11.2 General 3.11.2.1 MLS is a precision approach and landing guidance system which provides position information and various ground to air data. The position information is provided in a wide coverage sector and is determined by an azimuth angle measurement, an elevation angle measurement and a range (distance) measurement. 2007/70/II. szám C a ter Annex 10 — Aeronautical Communications 23/11/06 Note Unless specifically indicated as the M S airborne e uipment the text in refers to the M S ground e uipment 3.11.3 MLS configurations 3.11.3.1 asic M S The basic configuration of the MLS shall be composed of the following:
