DEPENDENT POSITION DETERMINING
1. DESCRIPTION
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 GPS Navigator transceiv-ers, GPS / WAAS GPS antennas, transponder, course deviation indicator (CDI), VOR/LOC antenna, HSI components, XM Weather system, Iridium Weather system, Automatic Direction Finder (ADF), and Dis-tance Measuring Equipment (DME) receiver and antenna.
A. GPS Navigator Transceivers
One or two VHF communications (COM) transceivers are installed to provide VHF communication. The transceivers and integrated controls are mounted in a single GNC 420(W) unit, single GNS 430(W) unit, GNS 430(W)/GNC 250XL units, GNS 430(W)/GNC 420(W) units, or dual GNS 430(W) units.
The transceivers receive all narrow- and wide-band VHF communication transmissions transmitted within range of the selected frequency. 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.
The Garmin GNC 250XL is an VFR certified VHF communications transceiver and GPS sensor. The GNC 250XL includes a removable data card.
The Garmin GNC 420 is an IFR certified VHF communications transceiver and GPS sensor. The trans-ceiver incorporates a GPS sensor and includes two removable data cards, one with a Jeppesen data base, and the second being a custom data card.
The Garmin GNC 420W is an IFR certified, WAAS capable VHF communications transceiver and GPS sensor. The transceiver incorporates a GPS sensor and includes two removable data cards, one with a Jeppesen data base, and the second being a custom data card. WAAS guidance functionality is avail-able to provide additional instrument approach options.
The Garmin GNS 430 is an IFR certified VHF communications transceiver and Navigation Manage-ment System (NMS). The NMS includes GPS sensor, VOR/Localizer and Glideslope receivers. The GNS 430 includes two removable data cards, one with a Jeppesen data base, and the second being a custom data card.
The Garmin GNS 430W is an IFR certified, WAAS capable VHF communications transceiver and Nav-igation Management System (NMS). The NMS includes GPS sensor, VOR/Localizer and Glideslope receivers. The GNS 430W includes two removable data cards, one with a Jeppesen data base, and the second being a custom data card. WAAS guidance functionality is available to provide additional instrument approach options.

(a) Pull STARTER RELAY and FUEL PUMP RELAY circuit breakers.(b) Set BAT 1, BAT 2, and AVIONICS switches to ON positions.
The NSD-360A HSI will begin to spin-up and stabilize when battery power is initially turned on. When the gyro reaches operational speed, the HSI "HDG" flag will retract from view and the compass card will stabilize.
(c) Set HSI switch to SLAVE position.(d) Rotate compass card to approximate magnetic heading.
Slaving meter will be at 45° when compass card matches heading. Verify slaving meter oscillates back and forth as compass card is rotated back and forth.
(e) Wait 5 minutes and verify the compass card remains on correct heading.(f) To test HSI navigation, perform Functional Test - Garmin 400 Series GPS Navigator
Setup. (Refer to 34-50)
CAUTION: Prior to verifying NSD-360A HSI system, verify that doors are closed, flaps are in retracted position, engine is running, and airplane is in level flight atti-tude.
Engine starting, taxiing, and shut-down may only be performed by autho-rized personnel.
Note: If compass rose is not available, a calibrated boresight compass may be used.

(1) Removal - NSD-1000 HSI(a) Set BAT 1, BAT 2, and AVIONICS switches to OFF positions.(b) Pull HSI#1 and HSI#2 circuit breakers.(c) Remove MFD. (Refer to 31-60)(d) Disconnect cable.(e) While supporting HSI, remove screws securing unit to instrument panel.(f) Cap off fittings on back of HSI to prevent possible contamination and remove HSI from air-
plane.(2) Installation - NSD-1000 HSI
(a) Position HSI in instrument panel and secure with screws.(b) Connect data cable.(c) Install MFD. (Refer to 31-60)(d) Reset HSI#1 and HSI#2 circuit breakers.(e) If NSD-1000 HSI is a different unit from the originally installed NSD-1000 HSI:
1 Perform Functional Test - Flux Detector Calibration with NSD-1000 HSI Installed. (Refer to 34-50)
2 Perform Operational Test - NSD-1000 HSI Setup. (Refer to 34-50)(f) If NSD-1000 HSI is the same unit as the originally installed NSD-1000 HSI:

(a) Pull STARTER RELAY and FUEL PUMP RELAY circuit breakers.(b) Set BAT 1, BAT 2, and AVIONICS switches to ON positions.
The NSD-1000 HSI will begin to spin-up and stabilize when battery power is initially turned on. When the gyro reaches operational speed, the HSI "HDG" flag will retract from view and the compass card will stabilize.
(c) Set HSI switch to SLAVE position.(d) Rotate compass card to approximate magnetic heading.
Slaving meter will be at 45° when compass card matches heading. Verify slaving meter oscillates back and forth as compass card is rotated back and forth.
(e) Wait 5 minutes and verify the compass card remains on correct heading.(f) To test HSI navigation, perform Functional Test - Garmin 400 Series GPS Navigator
Setup. (Refer to 34-50)
CAUTION: Prior to verifying NSD-1000 HSI system, verify that doors are closed, flaps are in retracted position, engine is running, and airplane is in level flight atti-tude.
Engine starting, taxiing, and shut-down may only be performed by autho-rized personnel.
Note: If compass rose is not available, a calibrated boresight compass may be used.
