1 GENERAL Dependent Position Determining 34-50: DEPENDENT POSITION DETERMINING 1. General This section covers that portion of the system which provides information to determine position from sources which are mainly dependent on ground installations. This includes the WAAS GPS 1/GPS 2 antennas, COM 1/COM 2 antennas, transponder, VOR/LOC antennas, XM Weather system, Iridium Weather system, Automatic Direction Finder (ADF), Distance Measuring Equipment (DME), and WiFi Datalink receiver and antenna. A. GPS Navigator Transceivers The airplane is equipped with two GIA 6xW integrated avionics units located behind the PFD and MFD, respectively. Integral to the GIA 6xW is an IFR certified, WAAS capable VHF communications transceiver and Navigation Management System (NMS). The NMS includes GPS sensor, VOR/Localizer and Glideslope receivers. The transceivers receive all narrow- and wide-band VHF communication transmissions transmitted within range of the selected frequency. For an overview of the GIA 6xW integrated avionics unit, see Central Computers section of Indicating And Recording. (Refer to 31-40) WAAS GPS1 and 2 antennas are mounted externally to the forward top of the nacelle. The COM 1 antenna is mounted externally to the center top of the nacelle. The COM 2 antenna is mounted externally to the center belly fairing. The VOR/LOC antennas are mounted externally to the LH and RH forward sides of the nacelle. The antennas pick up the signals and route the communication signals to the transceivers, which digitize the audible communication signal. The digitized audio is then routed to the audio control unit for distribution to the speakers or headphones. For GPS 1, 28 VDC is supplied through the 2-amp GPS NAV GIA 1 on EMER FP2, and for GPS 2 28 VDC is supplied through the 2-amp GPS NAV GIA 2 circuit breaker on ESS FP2. For COM 1, 28 VDC is supplied through the 2-amp GPS NAV GIA 1 and 5-amp COM 1 circuit breakers on EMER FP2. For COM 2, 28 VDC is supplied through the 2-amp GPS NAV GIA 2 and 5-amp COM 2 circuit breakers on ESS FP2. For VOR/LOC, 28 VDC is supplied through the 2-amp GPS NAV GIA 1 on EMER FP2 and the 2-amp GPS NAV GIA 2 on ESS FP2. The GPS Navigator Transceivers are integral to the integrated avionics system.

(b) (c) (d) Test antennas and associated cables for compliance with antenna manufacturer's published VSWR. NOTE There are two types of SWR tests that can be performed: 'continuous wave' for testing a single frequency or 'swept range' for testing a band of frequencies. Using IFR 4000 test set, connect UUT to test set through SWR connection. Use appropriate adapters as required. NOTE If using intermediate test set cable adapter to connect to the UUT instead of a direct connection to the SWR port, follow the SWR CAL procedure in the IFR 4000 Operations manual before proceeding. Select SWR Mode from test set menu. Continuous wave mode (CW MODE) is selected by default. Select SWEPT MODE to test a range of frequencies. Refer to the table below for the frequency or range of frequencies to be tested. 9
