If a lower CDI scale setting is selected (i.e., 1.0 or 0.3 nm) the higher scale settings are not be
selected during ANY phase of flight. For example, if 1.0 nm is selected, the GPS 500 uses this for
en-route and terminal phases and ramps down to 0.3 nm during approach. Note that the Receiver
Autonomous Integrity Monitoring (RAIM) protection limits listed below follow the selected CDI scale
and corresponding flight phases.

An arrival alarm, provided on the CDI / Alarms page, may be set to notify you with a message when
you have reached a user-defined distance to the final destination (the direct-to waypoint or the last
waypoint in a flight plan). Once you have reached the set distance (up to 99.9 units), an “Arrival at
[waypoint]” message is displayed.
The Airspace Alarms fields allow you to turn the controlled / special-use airspace message alerts on
or off. This does not affect the alerts listed on the Nearest Airspace page or the airspace boundaries
depicted on the Map page. It simply turns on/off the warning provided when you are approaching
or near an airspace.
An altitude buffer is also provided which “expands” the vertical range above or below an airspace. For
example, if the buffer is set at 500 feet and you are more than 500 feet above or below an airspace, you
will not be notified with an alert message; if you are less than 500 feet above or below an airspace and
projected to enter it, you will be notified with an alert message. The default setting is 200 feet.
