No, it is the flight manual supplement that is controlling. There may be
different supplements out there with different requirments too.

I have three 430/530 installations, two in the MU-2 and one in the Helio.
None of the Flight Manual Supplements require a current database for
approaches.


Does the language in the GNS530 pilots guide, page 4:

"The database confirmation page appears next and shows the current
database information on the NavData card (with the valid operating
dates, cycle number and database type included). The database is
updated every 28 days and must be current for approved instrument
approach operations."

not create a requirement that the database be current to use the unit
for GPS or overlay approaches?
