Page 1-18 GNS 400W Series Installation ManualRev. G 190-00356-08The navigation equipment required to join and fly an instrument approach procedure is indicated by thetitle of the procedure and notes on the IAP chart. Use of the Garmin GPS/SBAS receivers to providenavigation guidance during the final approach segment of an ILS, LOC, LOC-BC, LDA, SDF, MLS orany other type of approach not approved for ―or GPS‖ navigation is prohibited.Applicable to installations with GNS 430W Units: When using the Garmin VOR/LOC/GS receivers tofly the final approach segment, VOR/LOC/GS navigation data must be selected and presented on the CDIof the pilot flying the aircraft.Navigation information is referenced to the WGS-84 reference system, and should only be used wherethe Aeronautical Information Publication (including electronic data and aeronautical charts) conform toWGS-84 or equivalent.1.7 Database Options and Updates1.7.1 Aviation DatabaseThe aviation database resides on a database card that is inserted in the left card slot on the unit frontpanel.The database is generated on periodic cycles from current Jeppesen data and converted to the format usedby the 400W Series unit products. The data conversion process is performed using software that isdeveloped and maintained under Garmin document control processes according to RTCA/DO-200A,Standards for Processing Aeronautical Data.The database can be updated by purchasing a database subscription from Jeppesen. The database updatesinclude either replacing or re-programming the database card and inserting the updated card in the leftcard slot on the unit front panel. Contact Jeppesen at 800-621-5377 or www.jeppesen.com for moreinformation and instructions.Contact Garmin for more information on databases available for the 400W Series unit.1.7.2 Terrain/Obstacle DatabaseThe terrain/obstacle database resides on a database card that is inserted in the right card slot.The terrain/obstacle database is used for the terrain/obstacle display. For units configured for HTAWS, itprovides the database for the HTAWS function. The terrain and obstacle databases are available forupdating on periodic cycles and are available from Garmin. Terrain and obstacle database updates can bedownloaded via the internet and the card programmed using a USB programmer available from Garmin.Contact Garmin at 866.739.5687 or www.garmin.com for more information or instructions.See Section 3.3 for a listing of the data cards available.1.8 Fault Detection and Exclusion (FDE)The 400W Series unit, when installed as defined in this manual, complies with the requirements for GPSprimary means navigation in oceanic and remote airspace when used in conjunction with the FDEPrediction program included with the GNS 400W/500W Series Trainer CD.The 400W Series unit includes fault detection and exclusion (FDE), which is active for all flight phasesincluding oceanic and remote operations, en route and terminal, and precision and non-precisionapproaches, and does not require any pilot interaction. The FDE consists of two parts:1. The fault detection function detects a satellite failure that can affect navigation; and2. The exclusion function is the capability to exclude one or more failed satellites and prevent themfrom affecting navigation.The FDE Prediction program, included with the GNS 400W/500W Series Trainer CD, is used to predictFDE availability. The FDE Prediction program must be used prior to oceanic or remote area flights for alloperators using the 400W Series unit as primary means navigation under FAR parts 91, 121, 125, and 135.
