SECTION 13 - MESSAGES, ABBREVIATIONS, & NAV TERMS Message Description The flight plan (FPL) was truncated because not enough room existed to insert an approach, departure, or arrival. This message also appears when an approach has been deleted from FPL has been truncated a stored flight plan because an approach could not be found. These conditions may occur upon power up when a database change increases the number of waypoints in, or removes an approach from, an instrument procedure. FPL is full - remove An attempt has been made to add more than 31 waypoints to a flight plan (FPL). The GNC unnecessary waypoints 420 does not allow more than 31 waypoints per flight plan. FPL leg will not be smoothed The upcoming flight plan (FPL) leg is too short for smooth waypoint transitions. Expect a rapid change in the CDI. At least one flight plan (FPL) waypoint is locked because the waypoint has been removed FPL waypoint is locked from the current NavData Card (database change), the data card is missing, or the data card has failed. FPL waypoint moved The position data for one or more flight plan (FPL) waypoints moved at least 0.33 arc minutes in the current NavData Card (database change). FPL waypoint was deleted At least one flight plan (FPL) waypoint is no longer available when a new NavData Card was installed (database change). GPS has failed The GNC 420 has detected a failure in its GPS receiver. The GPS receiver is not available and the unit should be returned to a Garmin dealer for service. Internal system-to-system communication between the main processor and the GPS receiver GPS is not responding has failed. Operational status of the GPS receiver is unknown and the unit should be returned to a Garmin dealer for service. GPS needs service The GNC 420 has detected a failure in its GPS receiver. The GPS receiver may still be usable, but the unit should be returned (at the earliest convenience) to a Garmin dealer for service. GPS stored data was Satellite almanac, ephemeris and time data have been lost due to a memory battery failure, lost system reset, or data expiration (data over six months old). Inside airspace The GPS-calculated position lies within the boundaries of a special use airspace. This message is automatically disabled within 30 nm of an arrival airport, when an approach is loaded. Invalid closest pt of FPL A closest point cannot be created from the waypoint entered on the 'Closest point of flight plan' window. This occurs when the selected waypoint is beyond the limits of all legs in the flight plan, too far away, or when a unique waypoint name for the closest point cannot be created. 13-4 GNC 420(A) Pilot's Guide and Reference 190-00140-20 Rev.
