Page 108: Ils Approaches
SECTION 6 PROCEDURES 6.3 ILS APPROACHES Precision approaches can be performed with the GNS 430’ s built-in VLOC (VOR/localizer/glideslope) receivers. The GPS receiver can be used for guidance prior to reaching the final approach fix, but once there, the proper frequency must be selected on the VLOC Window (left side of screen) and the CDI output set to ‘VLOC’.
Page 109 The automatic switch from GPS to VLOC occurs gradually to prevent abrupt CDI changes when coupled to an autopilot. The CDI selection can also be changed manually by pressing the CDI Key. Once the switch from GPS to VLOC has occurred, either automatically or manually, it does not automatically switch again until the approach is reactivated or another approach is selected.

General Database Information Garmin TERRAIN uses terrain and obstacle information supplied by government sources. The data undergoes verification by Garmin to confirm accuracy of the content, per TSO-C151b. However, the displayed information should never be understood as being all- inclusive. Pilots must familiarize themselves with the appropriate sectional charts for safe flight.
Page 198 (compare database cycle numbers to determine if a newer version is available). Updated terrain data cards may be obtained by calling Garmin at one of the numbers listed in the front of this document. Updating terrain/obstacle databases: Acquire a new terrain data card from Garmin.

Page 210 SECTION 12 ADDITIONAL FEATURES Pilots should be aware of TAS/TCAS system limitations. If an intruder transponder does not respond to interrogations due to antenna shading or marginal transponder performance, it will not be displayed, or display may be intermittent. Pilots should remain vigilant for traffic at all times when using TAS/TCAS systems for non-transponder equipped airplanes or unresponsive airplanes.
Page 211 Aural Alerts A TA consists of a displayed traffic symbol (solid yellow circle) and an aural alert. The aural alert announces “traffic”, followed by the intruder aircraft’ s position, altitude relative to own aircraft (“high”, “low”, or “same altitude”), and distance from own aircraft; e.g. “traffic, 12 o’clock, high, 3 miles”.
Page 212 SECTION 12 ADDITIONAL FEATURES Switching Between Standby and Operating Modes The unit must be in operating mode for traffic to be displayed. The ability to switch out of standby into operating mode on the ground is especially useful for scanning the airspace around the airport before takeoff.
