Why aren’t there any approaches available for my route?

Approaches are only available when the final route waypoint or direct-to destina-

tion is an airport (some VOR/VORTAC identifiers are similar to airport identifiers). If
a destination airport does not have a GPS approach, the GPS 155 will display a ‘no
procedures in database’ message. For more on selecting an approach, see page 66.

What happens when I select an approach? Can I store a route with an
approach, SID or STAR?

Whenever you load an approach or STAR into the active route, the arrival airport

is moved, and a set of approach or arrival waypoints is inserted. If a SID is loaded
into the active route, the SID waypoints will be inserted following the departure air-
port in the active route. Note: these modifications only apply to the active route, and
will not affect the corresponding stored route (if you have activated one). Routes can
be stored with an approach, SID or STAR. Keep in mind that the active route is
erased when the unit is turned off and overwritten when another route is activated.

When storing routes with an approach, SID or STAR, the GPS will use the way-

point information from the current database to define the waypoints. If the database
is changed or updated, the GPS 155 will automatically update the information if the
procedure name has not changed. If an approach, SID or STAR procedure is no
longer available, the route will become locked until the procedure is deleted from the
route or the correct database is installed. For information on loading an approach,
SID or STAR, see pages 79-82. See page 54 for instructions on saving and copying
routes.

Can I file slant Romeo ‘/R’ using my GPS?

Yes, you may file your flight plan as /R if your GPS 155 is a certified A1 or A2

installation. If you are flying enroute, you may fly /R with an expired database

only

after you have verified all route waypoints. Non-precision approaches

may not

be

flown with an expired database. See your approved Airplane Flight Manual
Supplement for more information.
