Approaches for software 2.40 and later

Garmin's GNS 480 database keeps 96 RNAV (GPS) approaches that software earlier than 2.40 could not fly with correct CDI scaling (Garmin Service Bulletin 1519, GNS 480 (CNX80) Software Upgrade to Version 2.4 with GPS Software Upgrade to Version 5.1, 16 April 2015) in a separate part of the database that only software 2.40 and later reads. Our databases do exactly the same with the same list, so a unit with software 2.40 or later sees the same approaches as with Garmin's card, and an older unit sees the same reduced set.

Each cycle

For each published cycle: the RNAV airways left out, and every other procedure, runway or localizer that is left out of the database or stored with a condition, grouped by reason. Open a group to see its items.

The GNS 480 cannot accurately encode an RNAV airway (T-route or Q-route) that has a DME-only or TACAN-only navaid in its airway definition. These airways are left out of the database.
