GUIDANCE MATERIAL ON THE PRE-FLIGHT CHECKING OF VOR AIRBORNE E UIPMENT 1. Specification for a VOR airborne equipment test facility (VOT) 1.1 Introduction For the guidance of States wishing to provide a test signal for the pre-flight checking of VOR airborne equipment, suggested characteristics for a VOR airborne equipment test facility (VOT) are given hereafter. 1.2 General 1.2.1 The VOT must be designed to provide signals that will permit satisfactory operation of a typical VOR aircraft installation in those areas of the aerodrome where pre-flight checking is convenient and desirable. 1.2.2 The VOT must be constructed and adjusted so that the VOR bearing indicator in the aircraft will indicate zero degrees “FROM” when the receiver has not departed from calibration. This indication remains constant irrespective of the aircraft s angular position with respect to the VOT within the intended coverage. 1.2.3 In view of the manner in which use is made of a VOT, there is no fundamental need for its duplication at any one site. 1.2.4 The VOT is required to radiate a radio frequency carrier with which are associated two separate 30 Hz modulations. The characteristics of these modulations should be identical with the reference phase and variable phase signals associated with VOR. The phases of these modulations should be independent of azimuth and should be coincident with each other at all times. 1.3 Radio frequency The VOT should operate in the band 108 to 117.975 MHz on an appropriate VOR channel selected so as not to interfere with any VHF navigation or communication services. The highest assignable frequency is 117.95 MHz. The frequency tolerance of the radio frequency carrier should be plus or minus 0.005 per cent, except as specified in Chapter 3, 3.3.2.2 and 3.3.2.3. 1.4 Polarization and accuracy 1.4.1 The emission from the VOT should be horizontally polarized. 1.4.2 The accuracy of the “bearing” information conveyed by the radiation from the VOT should be plus or minus 1 degree. Note.— Since the two modulations on the radio frequency carrier are in phase coincidence at all times, the vestigial vertically polarized energy will have no effect on the accuracy of the facility. ANNEX 10 — VOLUME I ATT E-1 23/11/06 2007/70/II. szám Annex 10 — Aeronautical Communications Volume I 1.5 Coverage 1.5.1 Coverage requirements, and hence the power which must be radiated, will necessarily depend to a considerable extent on local circumstances. For some installations, a small fraction of 1 W will suffice while in other cases, particularly if two or more closely adjacent aerodromes are to be served by a single test facility, several watts of radio frequency energy may need to be emitted. 1.5.2 Where there is a need to protect co-channel VORs, VOTs and ILS localizers from VOT interference, the radio emission must be limited to that required to provide satisfactory operation and to ensure that interference with other co-channel assignments does not occur. 1.6 Modulation 1.6.1 The radio frequency carrier as observed at any point in space should be amplitude modulated by two signals as follows:
