Approach Operations
NMS Approach Procedure
There are three general types of NMS operation (see diagram on the
next page): En route, Approach Transition (or Approach Enabled) and
Approach Active. When conducting an approach, your Apollo NMS
will progress from En Route to Approach Transition when the pilot
enables the approach, then to Approach Active, and possibly back to
Approach Transition in the event of a missed approach.

En route Operations
En route Operations describe all operations prior to 30 nm from your
destination airport. Your Apollo NMS is providing En route operation
whenever the Approach annunciator light is not on. The default CDI
sensitivity for en route is 5.0 nm; however, you may manually select
other CDI sensitivities. Generally, you will select your destination
airport prior to departure or while en route, and you will usually select
and load an anticipated approach from the database into your active
flight plan while en route.
An approach can only be selected for an airport when it is
the last waypoint in your active flight plan.
