Transition
Operation
(Enabling
Approach)
Approach Transition Operation begins when you
enable an approach that has already been selected
from the database and loaded into the active flight
plan. The Approach annunciator will be on (and the
Approach Active annunciator will be off) to indicate
that your Apollo GX is operating in Approach
Transition. The CDI sensitivity is locked at 1.0 nm
for Approach Transition.
Approach Transition Operation will usually be
preceded
by En Route Operations. Approach
Transition will be preceded by Approach Active in the
event of a missed approach or a canceled approach.
Note that there are two methods to enable an
approach.
Enable Approach - Method 1
Press
ENTER when the “Enable Approach?” prompt is
displayed as a message. The message will occur when
an approach is loaded from the database and the
aircraft is 30 nm or less from the destination airport.
This message-prompt is repeated at 3 nm inbound to
