It is up to the EGPWS customer to determine if a specific database update is applicable to their operation. Honeywell estimates that EGPWS customer will update their database approximately once every 2 years.
NOTE: Some database updates may require a hardware or software mod.  Any required modification information will be identified in the associated database Service Bulletin.

4.2.2 LOADING A DATABASE
A database is loaded into the EGPWC via the PCMCIA card slot in the front panel in the MK V and MK VII.  In the MK VI and MK VIII, a “Smart Cable” data-loader is connected to the Test connector on the front panel.  The database may be loaded either while the EGPWC is on the aircraft or on a bench provided the appropriate power is applied.
Each Honeywell database Service Bulletin includes the procedure for loading the database in the EGPWC.  Refer to the Service Bulletin for this information.

In flight, the EGPWC records detected faults, and data prior to and following an alert.  This flight history data can be downloaded from the EGPWC via the PCMCIA interface.  With this data, Honeywell can analyze the flight history when necessary to help in the troubleshooting process, or analyzing special or unique events.
