ALTITUDE CALLOUT
When an IFD is configured with the F500 or HTAWS options
enabled, an aural alert can be played anytime the aircraft descends
through one of several defined AGL altitudes. The AGL altitude is
calculated by comparing GPS MSL altitude with elevation of either
the destination runway threshold, if applicable, or the terrain directly
beneath the aircraft. Alerts exist at 1000', 500', 400', 300', 200', and
100' AGL. The callout for each altitude can be enabled or disabled
using Maintenance Mode.
These callouts are intended for use during approach to landing.
Therefore, they are not suppressed in FLTA exclusion area, but will
not play while there is an active FLTA caution or warning. The
enabled callouts, as a set, can be turned on or off using the Setup
Page.
