SYSTEM DESCRIPTIONS7.1 Pilot’s GuideSee Garmin 4XXW Series unit Pilot’s Guide for a complete description of the4XXW Series unit.7.2 Manual GTN CrossfillManual GTN Crossfill is a feature that will keep the GNS system in sync with aflight plan that is being used on the GTN system. The GTN will notautomatically keep its flight plan in sync with changes made on the GNS system.Manual crossfill feature is “one way” – from the GTN to the GNS.The GTN systems support a variety of procedure leg types that the GNS systemsdo not support. As such, it is normal and expected that the flight plan leg that isdisplayed on the GNS system will not always match the flight plan leg on theGTN system. Departure, arrival and approach procedures contain leg types thatthe GNS does not support. The GNS typically “skips” over these leg types andprovides no guidance. Guidance may be available on the GTN but not on theGNS in these cases. The GNS will sequence the procedure as it normally wouldif Crossfill were not active. Once a leg type is reached that is supported on boththe GTN and GNS systems, the systems will automatically sync to the same leg.If a GNS is interfaced with a GTN then autoswitching from GPS to VLOCguidance on the CDI for ILS/LOC approaches will be disabled on the GNS.If the flight plan on an interfaced GTN is altered while in a hold, the GNS willreinitiate guidance to the holding waypoint and sequence into the hold uponcrossing the waypoint.If the Missed Approach is activated on the GTN prior to reaching the MissedApproach Point, the GTN will automatically resume leg sequencing uponreaching the Missed Approach Point. The GNS will remain suspended uponreaching the Missed Approach Point and leg sequencing must be manuallyresumed.
