Message Description
FPL has been truncated
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
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
unnecessary waypoints An attempt has been made to add more than 31 waypoints to a flight plan (FPL). The GNC
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.
FPL waypoint is locked
At least one flight plan (FPL) waypoint is locked because the waypoint has been removed
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.
GPS is not responding
Internal system-to-system communication between the main processor and the GPS receiver
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
lost Satellite almanac, ephemeris and time data have been lost due to a memory battery failure,
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.
