AIRWAYS AND DATABASE UPDATES
The G1000 allows saving stored flight plans with airways on them. When the database is updated, the
airways will need to be reloaded in a fashion similar to what is done for departures, arrivals and approaches.
The basic process is that each airway segment is reloaded from the database given the entry waypoint, the
airway identifier and the exit waypoint. This re-loads the sequence of waypoints between the entry and exit
waypoints (the sequence may change when the database is updated).
If “optional” airway waypoints have been inserted within the airway sequence, those waypoints will be
included when the airway is updated whenever possible.
The update of an airway can fail during this process. If that happens, the airway is removed from the flight
plan. The following things could cause the airway update to fail:
• Airway entry waypoint or exit waypoint not found in the new database
• Airway identifier not found in the new database
• Airway entry waypoint is not an acceptable entry waypoint for the airway – either the waypoint is no longer
on the airway, or there is a new directional restriction that prevents it being used as an entry waypoint.
• Airway exit waypoint is not an acceptable exit waypoint for the airway – either the waypoint is no longer
on the airway, or there is a new directional restriction that prevents it being used as an exit waypoint (given
the entry waypoint)
• Loading the new airway sequence would exceed the capacity of the flight plan
