to be applicable:
NOTE
This section is not intended to be a comprehensive list of approved software. It is
intended to provide a means to determine if this AFMS revision is applicable to the

installation has a software version less than that shown in the table above.
2.2 Standby Flight Instruments
Standby Instruments are required for aircraft approved for IFR operations.

internal G3X Touch GPS navigation source is selected.

the word “HELI” or “HELICOPTER” in their title, as displayed on the database status page.
